1960, the state organized the annual oil battle and put it into experimental development. At the end of 1963, Daqing Oilfield ended its experimental development and entered a comprehensive development and construction. Three main oilfields, Sarthou, Xingshugang and Lamadian, have been developed successively, and a number of new oilfields have been explored and prepared. The development and construction of Daqing Oilfield got rid of the label of "poor oil" in China.
As of June, 20021year, Daqing Oilfield has greatly improved its oil recovery technology through independent innovation of compound flooding, reaching the international leading level. Composite flooding has become a strategic alternative technology in the annual oilfield, making China the only country in the world that has applied composite flooding technology on a large scale.
Daqing oilfield resources:
The petroleum exploration scope of Daqing includes 720,000 square kilometers in Heilongjiang Province and Hulunbeier League in Inner Mongolia Autonomous Region, accounting for113 of the land area of China. Among them, Songliao Basin covers an area of 260,000 square kilometers, spanning Heilongjiang, Jilin and Liaoning provinces, accounting for about 6.5438+0.2 million square kilometers of Heilongjiang.
In geological history, it used to be a large inland lake basin, which was rich in oil-generating materials in Mesozoic Jurassic and Cretaceous. The thickness of sedimentary rocks in the center of the basin exceeds 7000 to 9000 meters. According to records, according to scientific prediction, there are at least100-1500 million tons of oil reserves in this area, and the recoverable oil reserves are 80-100 billion tons.
