On June 15, 2007 (May 1, 2007 in the lunar calendar), the guide Jiao Liren passed away. Photo: Jiao Liren In the history of the development of the petroleum industry in New China, Jiao Liren was one of the main organizers of several early large-scale oil battles, leaving his footprints in almost every oil field in the country. In the history of Yanchang Petroleum's development, he conducted in-depth research on Yanchang Petroleum's oil ore many times and organized the "82 Symposium", which unlocked the shackles of Yanchang Petroleum's lagging development and played an important role in the multi-level development of northern Shaanxi petroleum. It is the guide and founder of Yanchang Petroleum's new journey. Jiao Liren was born in Hancheng County, Shaanxi Province in August 1920. He studied at Lu Xun Normal School in the Shaanxi-Gansu-Ningxia Border Region in 1938 and joined the Communist Party of China in November of the same year. It was also that year that I first came into contact with oil because I visited the Yanchang Oil Mine while in Yan 'an. In 1949, he took over the Yumen Oil Mine, began to learn petroleum knowledge, and entered the petroleum industry. He served as deputy secretary, deputy minister and consultant of the Party Leadership Group of the Ministry of Petroleum Industry. In June 2007, he died of illness in Beijing at the age of 87. The "82 Symposium" lifted the shackles of Yanchang's oil development and extended the development of oil production from less than 80,000 tons in 1982 to 10 million tons in 2007. One person contributed greatly, and this person was Jiao Liren. The "82 Symposium" he organized lifted the shackles of Yanchang Petroleum's lagging development and allowed Yanchang Petroleum to stand confidently in front of the Chinese people and the world. From July 21 to August 5, 1982, Jiao Liren, a 62-year-old consultant to the Ministry of Petroleum Industry, led a 17-member expert working group to conduct in-depth investigation and research on the oil ore. Braving the raging fire of July, they climbed mountains and waded through water, went deep into the drilling well site, the oil production team, the fracturing site, next to the well repair truck, and the mechanical repair workshop to conduct a detailed inspection. While affirming that Yanchang Oil Mine has developed oilfield production and construction by using drilling, fracturing trucks, wellhead tanks, and small refineries according to local conditions, it also deeply understands the shortage of funds, non-implementation of economic policies, and insufficient profit retention in the development of Yanchang Oil Mine. Reasonableness and other constraints that restrict the development of the oilfield. The working group believes that only by making a decision to solve these problems can we promote the expansion of Yanchang Oil production. Therefore, a symposium on Yanchang Oil Mine Development Planning was organized. From August 6 to 8, 1982, the Ministry of Petroleum Industry, Shaanxi Province and Yan 'an Prefecture held a symposium on the development planning of Yanchang Oil Mine in Yan' an, and formulated preferential policies for Yanchang Oil Mine of "using oil to support oil, combining mining and refining, and rolling development." It mainly includes: First, the Ministry of Petroleum Industry and the Ministry of Finance subsidize the investment in the capital construction of Yanchang Oil Mine by 2.5 million yuan every year; the Ministry of Petroleum Industry allocates 500,000 yuan in geological service expenses every year; Shaanxi Province invests 1.5 million yuan in the capital construction of Yanchang Oil Mine every year; 80 yuan is extracted from production costs per ton of crude oil to support the development of northern Shaanxi Oil. Second, Yanchang Oil Mine has an annual production capacity of 70,000 tons, which is supplied to oil companies with affordable petroleum products. The excess production is priced at exported crude oil, and the balance of income belongs to the oil mine as an exploration and development fund. In March, before 1985, Yanchang Oil Mine handed over a profit of 1.2 million yuan every year to Yan 'an, and the part exceeding the limit was returned to the oil Mine as exploration and development funds. This policy is called the preferential policy of "using oil to support oil, combining mining and refining, and rolling development". It is a turning point in the rapid development of Yanchang Oil Mine, a gas station for Yanchang Oil Mine to move forward rapidly, and an important milestone in the century-old development history of Yanchang Oil Mine. Multi-level development and development of petroleum to revitalize the local economy Jiao Liren was the organizer and promoter of the China Petroleum War. The multi-level development of petroleum in northern Shaanxi was the masterstroke of his life on the oil battlefield. Jiao Liren, who is in love with Yanchang Petroleum, has led a group of old petroleum and experts to conduct in-depth research on Yanchang Oil Mines almost every year since 1982, helping Yanchang Oil Mines solve problems and formulate scientific development and sustainable development plans. In May 1986, when he heard the news that the Yanchang County Drilling and Production Company established the year before had produced 1005 tons of crude oil that year, he went straight to the drilling and production company. He was extremely excited: he finally found a way to get rid of poverty in Yan 'an. Because the most abundant resource underground in Yan 'an is oil, and the production cost of drilling and production companies is much lower than that of Changqing Exploration Bureau and Yanchang Oil Mine, allowing local governments to exploit marginal blocks is a major breakthrough in the oil industry. Jiao Liren, who was over 60 years old, couldn't help but be passionate. He splashed ink and wrote an inscription celebrating the first anniversary of the country's first county-run petroleum enterprise: Developing petroleum to revitalize the economy and benefiting many parties from joint operations. Jiao Liren, a war general in the China oil battle, keenly grasped the successful path of multi-level development of northern Shaanxi oil. In November 1986, the first snow fell in northern Shaanxi. He was not afraid of the cold weather and led leaders and experts from relevant departments such as the Planning Department, Development Department, Finance Department of the Ministry of Petroleum to the Yanchang Oil Administration Bureau again, braving the biting cold wind, went deep into the drilling team, oil production team, and fracturing site for on-site investigation. Subsequently, from the 29th to December 1st, a Yan 'an Petroleum Work Symposium was organized and held at Yan' an Hotel. In addition to the leaders of the Ministry of Petroleum Industry, Yun Hanchang, consultant of Changqing Petroleum Exploration Bureau and Shaanxi Province Petrochemical Department, Xue Zhiyong, deputy commissioner of Yan 'an Administrative Office, and leaders of relevant departments and counties and cities in Yan' an region were also invited to discuss the plan. The "Minutes" of the meeting pointed out that petroleum resources are owned by the state, and the development and utilization of petroleum resources in Yan 'an area are entrusted by the Ministry of Petroleum to the Yanchang Oil and Mineral Administration Bureau to manage, produce and operate uniformly, and can be contracted by local governments to benefit local governments. The meeting also studied and decided on system, equipment technology and leadership management issues. The four oil mines affiliated to the Yanchang Oil Administration Bureau focus on developing high-yield blocks. The marginal wells and some low-yield wells of the oil field are contracted by counties (cities), mobilizing counties (cities) to develop oil at multiple levels. "One flower brings hundreds of flowers to bloom." After the establishment of Wangjiachuan Petroleum Drilling and Production Company in Yanchang County in 1985, drilling and production companies have mushroomed across northern Shaanxi. From 1987 to 1993, Nanniwan, Qingpingchuan, Zhiluo, Xiasiwan, Wayaobao, Xingzichuan, Yongning, Yingwang, Wuqi and other drilling and production companies were established in Yan 'an. From 1990 to 1993, four drilling and production companies were established in Yulin: Jingbian, Zizhou, Hengshan and Dingbian. The development of drilling and production companies can be said to have the right time, location, and harmony with people. They have sprung up like a sudden force. By 2005, the total output of petroleum restructuring in northern Shaanxi reached 5.0783 million tons, accounting for more than 60% of Yanchang's total oil output (8.3824 million tons). After reorganization, Yanchang Petroleum has become even more powerful and developed rapidly. In 2007, on the 100th anniversary of oil production, it produced 10.3169 million tons of crude oil, breaking through the 10 million tons mark, realizing the long-cherished wish of generations of Yanchang Petroleum people to enter the ranks of the country's largest oil fields. After the "82 Symposium" on the Development of Old Mines, Yanchang Oil Mine has taken big steps and moved faster, opening a new journey in an all-round way. Jiao Liren has returned to Shaanxi and northern Shaanxi dozens of times to provide suggestions and suggestions for the development of Shaanxi's petroleum industry in terms of market opening, multi-level development, technology introduction, cleanup and rectification, reorganization and integration, so that the blood of Yanchang Petroleum can maintain sufficient vitality and motivation. In August 2004, when he participated in the "Centenary Development Symposium of Yanchang Oil Mine Ultra-Low Permeability Oilfield" and saw Yanchang Oil's plan to exceed 10 million tons of crude oil output in 2007, he happily said: I will definitely come and congratulate you then. In October 2005, on the 100th anniversary of the founding of Yanchang Oil Mine, Jiao Liren sent a congratulatory message congratulating Yanchang Oil Mine on "making greater contributions to the development of my country's petroleum industry and promoting and promoting the economic and social development of old revolutionary areas." God failed to meet his wishes. In December 2006, Jiao Liren was admitted to Peking Union Medical College Hospital, and Yanchang Petroleum sent representatives to visit him. When they arrived on the afternoon of the 8th, Jiao Liren had just fallen asleep after the injection, but when his wife whispered in his ear that someone from Yanchang Oil Mine had come to see you, he suddenly woke up and insisted on sitting up. When he heard that Yanchang Oil Mine produced 9.3 million tons of crude oil that year and would definitely exceed 10 million tons in 2007, a smile quickly appeared on Lao Jiao, who had been bedridden in the hospital for a long time and had almost no expression for a long time., nodded gently from time to time, opened his dry mouth that had not been opened for many days, and said intermittently: 'I... Growing up drinking Yanhe River, I am... Son of the people of Yan 'an... I will definitely participate... Celebration meeting... At 21:40 on June 15, 2007, Comrade Jiao Liren passed away in Beijing due to ineffective medical treatment at the age of 87. However, his life of struggle, his life of dedication, and the wisdom and effort he devoted to running for Yanchang Oil will never be forgotten by Yanchang Oil people.
