白云岩是碳酸盐岩的重要岩类,对于油、气聚集具有特殊的意义。各碳酸盐岩的含油、气都不同程度与白云岩有关。已查明由于白云岩的成因不同,对油、气的聚集也具有不同的意义。白云岩化作用不仅能引起孔隙度的变化,而且也能控制碳氢化合物的聚集形成油捕。因此在碳酸盐岩含油、气区研究白云岩的成因是认识该区油、气聚集机制的基本问题之一。任邱油田是我国碳酸盐岩含油、气区的一个高产油田,它是白云岩含油。由于油层深埋
Dolomites are important rock types of carbonate rocks and have special significance for oil and gas accumulation. The carbonate oil, gas are different degrees and dolomite. It has been ascertained that the accumulation of oil and gas has different meanings because of the different causes of dolomite. Dolomitization can not only cause changes in porosity, but also control the accumulation of hydrocarbons to form oil traps. Therefore, it is one of the basic problems to understand the mechanism of oil and gas accumulation in carbonate oil-bearing and gas-bearing dolomite. Ren Qiu oil field is a high-yield oil and gas field in carbonate oil-bearing area in China, which is oil-bearing dolomite. As the reservoir buried
