摘要
本文通过对排替压力的测试、饱和不同流体的排替压力转换以及温度校正,对朝长地区青山口组泥质盖层的实际封闭能力进行了评价。并对现今具有封闭能力的盖层进行了封闭史恢复,结合气源岩的排烃史,分析了盖层封闭的有效性。
Displacement pressure is a dominating parameter in the evaluation of the sealing ability of a cap rock. Based on a technique of transformation of the displacement pressure saturated by different kinds of fluid and the variation of the displacement pressure under various temperature, this paper evaluated the actual sealing ability of Qingshankou formation in Chaochang area as a gas cap rock. Then, the sealing history of the cap rock is restored according to the history of hydrocarbon repulsion of source rock, effectiveness of the sealing of the cap rock is analyzed. Some new ideas in this respect are suggested in this paper.
