摘要：

濮城油田沙河街组二段下亚段(简称沙二下)油藏经历了近20年开发,目前含水高达92.%.因此,须探讨高含水情况下剩余油的分布规律,以调整开发方案.濮城油田剩余油分布主要受构造、沉积相及井网密度的影响,可分为种分布型式 :(1)连片分布差油层型.该类型的剩余油主要分布于各小层的河道间相(Q)和远砂坝砂坪相 (Y),须进行油层改造后,方可动用.(2)注采不完善型.此类型的剩余油主要分布于沙二下 6～8砂层,在现有工艺条件下,暂不宜开发.(3)断层遮挡型.这种类型的剩余油主要分布于濮46,49,25,14等大断层的上升盘,可通过布定向井进行开发.

Abstract:

After nearly 20 years of production,the water cut of the oil pool in the lower Sha 2 submember is up to 92.3%.The distribution of residual oil is influenced basically by structures,sedimentary facies and well density,and could be divided into 3 types:(1)discontinuous oil layers.This type of residual oil is mainly distributed in interchannel facies(Q),distal bar and sand flat facies(Y).The oil layers should be reformed before recovery;(2)incompleted injection recovery type.This type of residual oil is mainly distriuted in the 6th～8th sandbodies of lower Sha 2 submember,and it is not suitable for recovery at present;(3)fault sheltered type.This type of residual oil is distributed in the upper walls of Pu 46, 49, 25 and 14 faults,and could be recovered by directional well allocation.
