河68断块剩余油分布及开采对策

Remaining oil distribution and production strategy of He 68 fault block.

复杂断块油藏的剩余油在平面、层间及层内的分布异常复杂。根据现阶段对油藏的认识及资料应用技术 ,对胜利油区现河油田河 6 8断块进行了地震构造地质精细成图 ,对其主要开发层系进行了沉积微相划分 ,指出剩余油主要集中在构造高部位、断层附近及井网不完善区 。

The areal, in-layer and inter-layer distribution of remaining oil in complicated fault block reservoirs is very complex. Fine geologic mapping of seismic structure is made for He 68 fault block of Xianhe oilfield in Shengli petroliferous province based on the present knowledge of the oil reservoirs and reservoir data. Sedimentary micro-facies is classified for the major production series of strata. It is pointed out that the remaining oil is distributed at structure high position, near faults and areas of poor well pattern and it is suggested that lateral drilling and well pattern modification should be taken as the dominant measure for recovering the remaining oil.
