Shengli Oilfield: Independent Innovation to Build a Century Oilfield
Guided by theoretical breakthroughs and technological innovations, Shengli Oilfield discovered that in the past 50 years, the production of crude oil has exceeded 1 billion tons, and the old oil district has been rejuvenated. On the artificial island of the Yellow River in the Bohai Bay, which has only three football fields, Shengli Oilfield has 57 wells, each with a spacing of only 5 meters. Horizontal well technology, using the drill bit to drill vertically to a certain depth, can make a diagonal "turn", traverse the formation, and maximize the oil layer. This technology has set a number of more than 40 national first. In the late 1970s, oil and gas exploration in Shengli Oilfield entered the lowest valley. From 1976 to 1980, the newly-added proved reserves in the five years were only over 100 million tons. In the face of such a severe situation, the victors emancipated their minds and summarized the "double type." "The theory of oil and gas accumulation belt. Guided by this theory, from 12 years from 1983 to 1994, 23 oil and gas fields such as Gudong and Zhuangxi were discovered. The proven reserves exceeded 2 billion tons, and the highest proven reserves reached Amazing 410 million tons, oil and gas production has exceeded 30 million tons for 9 consecutive years. The birth of the hidden oil and gas reservoir exploration theory system has made the exploration situation of Shengli Oilfield suddenly clear. By 2010, the oilfield has achieved balance of reserves and production for 14 consecutive years, and the tertiary reserves have been continuously 8 Over 100 million tons, the proven oil geological reserves have exceeded 100 million tons for 28 consecutive years.
