【摘要】 以气势的分布及其在地质历史时期的演化为基础,考虑到流体动力与油气运聚的关系,再根据油气运聚系统的划分原则,对下白垩统巴什基奇克组在不同地史时期的天然气运聚系统进行了划分和研究,探讨了天然气的聚集和成藏规律。同时结合运聚系统、低势区的分布及其演化特点、生烃中心位置及断裂发育情况,对天然气的运移方向做了进一步的综合分析。更多还原

【Abstract】 Based on gas potential distribution and evolution in geologically history periods,thinking of relation between with fluid dynamic and hydrocarbon migration accumulation.According of principia which hydrocarbon migration and accumulation systems is compartmentalized,nature gas migration and accumulation systems of lower Cretaceous period Jidike is compartmentalized and studied,nature gas accumulation is discussed,at the same time,according of the migration and accumulation systems and the distribution and evolution characteristic of lower potential area and center location which hydrocarbon is formed and development situation of fault,nature gas migration direction is analyzed synthetically.更多还原
