摘要/Abstract

摘要： 为了研究断裂在油气成藏与分布中的作用，在分析盖层封气综合能力及其研究方法的基础上，利用天然气在剩余压力作用下通过盖层向外渗滤散失压力梯度的大小，表征盖层封气综合能力的好坏；依据被断裂破坏前后盖层封气综合能力差值与被断裂破坏前盖层封气综合能力的比值，建立了一套断裂对盖层封气综合能力破坏程度的定量研究方法。以渤海湾盆地南堡凹陷南堡5号构造东二段泥岩盖层为例，对NP5-2断裂对东二段泥岩盖层封气综合能力的破坏程度进行了定量研究。结果表明：南堡5号构造NP5-2断裂对东二段泥岩盖层封气综合能力的破坏程度较高，除L6测线处为弱破坏程度和L1、L5、L8测线处为中等破坏程度外，其余5条测线处均可达到较强和强破坏程度；且NP5-2断裂对东二段泥岩盖层封气综合能力的破坏程度西部强于东部，这与东二段泥岩盖层之下储气层中目前已发现的天然气主要分布在断裂东部相吻合。该方法用于定量研究断裂对盖层封气综合能力破坏程度是可行的。

Abstract: To study the role of fault in oil-gas accumulation and distribution,based on the study of the caprock comprehensive sealing gas ability and its study method,characterizing caprock comprehensive sealing ability by utilizing pressure gradient of gas under residual pressure dissipating outwards through caprock, by comparing the difference of the caprock comprehensive sealing gas ability before and after caprock destroy and that after caprock destroyed by faults,we set a quantitative study method of destruction degree of faults to caprock comprehensive sealing gas ability,and made an example of Ed₂ mudstone caprock in No.5 structure zone from Nanpu sag of Bohai bay basin,finally carried out a quantitative study of destruction degree of NP5-2 Fault to Ed₂ mudstone caprock comprehensive sealing gas ability. the result indicated that, the regional destruction degree was preferably high,except for week destruction degree in L6 survey line, and intermediate weak destruction degree in L1, L5, L8 survey lines. The destruction degree was preferably strong in the west than the east,and it coincided well with the distribution of present found gas below Ed₂ mudstone caprock gas reservoir in the east part of fault. This method is feasible to quantitatively study the destruction degree of faults to caprock comprehensive sealing gas ability.

Key words: fault, caprock, comprehensive sealing gas ability, destruction degree
