The history of Ren Sijing

On July 3rd, 1975, Rensi Well, located in Xinzhongyi structural zone in Renqiu, Hebei Province, liked to spray high-yield industrial oil flow, with a daily output of1kloc-0/4 tons (there are not many oil wells with a daily output of more than 100 tons in China), thus uncovering the eternal mystery of buried hill reservoir and announcing the birth of North China Oilfield.

Well Ren-4 is a meritorious and efficient well. Since it was put into production, the waterless oil production period has reached more than 4,400 days, the waterless oil production has reached 65.438+0.55 million tons (calculated by the current crude oil price, the output value of a single well has reached as much as 5.6 billion yuan), and the flowing high production has reached 65.438+06 years, creating a miracle in the history of oil exploration and development in China. It was not until 199 1 year 1 year 1 month 65438+5 that the first operation was started, and the production was changed to electric pump pumping unit. Today, this well still maintains a certain oil production potential.

The birth of Well Ren-4 not only created the miracle of Buried Hill Oilfield, but also greatly enriched and developed China's petroleum geology theory. Therefore, many buried hill reservoirs have been discovered in Dagang, Shengli, Liaohe and other oilfields, which has opened up new ideas for oil exploration. Then from the second half of 1975 to the beginning of the second year, six wells including Ren 6, Ren 7, Ren 9, Ren 1 1 were drilled successively, among which Ren 9 produced 5,435 tons of crude oil per day, which was the highest in China. "Six wells decide the overall situation" was once a popular story in the whole country, and the big scene of oil exploration in North China emerged from it.

1976, the State Council approved large-scale oil exploration and development in central Hebei. Subsequently, more than 30,000 employees from Dagang, anniversary, Shengli, Changqing, Yumen and other oilfields went to Huabei Oilfield, producing 5.97 million tons of crude oil in that year, realizing exploration, development and construction in that year, and fully recovering state investment in that year, creating an unprecedented speed in the history of contemporary petroleum industry. Since 1977, Huabei Oilfield has maintained an annual output of crude oil of more than 100000 tons for10.

At present, a jujube monument stands at the well site of Rensijing, which is engraved with several characters inscribed by Zhang Wenbin, former vice minister of petroleum: Rensijing, a discovery well in North China's buried hill oilfield. Well Ren 4, the "Meritorious Well", was named as the spiritual education base of China petroleum enterprises because of its unique position and contribution. At present, more than 50 thousand tourists have come here.
