Daqing oil exploration scope, including all of Heilongjiang Province and Inner Mongolia Autonomous Region Hulunbeier a total of 72 million square kilometers of the vast region, occupying a land area of China's 1/13. Wherein the Songliao Basin area of 260,000 square kilometers, spanning Heilongjiang, Jilin and Liaoning provinces, Heilongjiang territory about 12 million square kilometers. In geological history, there was a large inland lake, Mesozoic Jurassic and Cretaceous period, deposited rich oil source material. Thickness of sedimentary rocks of the basin center 7000-9000 meters. According to records, in this region, scientific prediction, bears at least 100-150 million tons of oil reserves, for the exploitation of oil reserves of 80-100 one hundred million tons; total gas reserves of 8580-42900 billion cubic meters. Daqing oilfield development since 1960, proven oil-bearing area of 4415.8 square kilometers, geological oil reserves of 5.587 billion tons.
Daqing Petroleum medium gravity, high viscosity, high wax content, high freezing point, very little sulfur content, commonly referred to as the "three high and one low", is a low-sulfur paraffin-based type, is the ideal petrochemical feedstocks. Daqing area gas resources buried in 700-1200 meters or more in shallow and deep formations, was buried deposit status. It is associated with oil, natural gas containing 50-70 cubic meters per ton of crude oil; it is predominantly methane, accounting for 64.5-91.3%, can be directly used as raw material for the production of fertilizers; high condensate content per cubic meter 70-170 g as much as a high industrial value本回答被网友采纳
