摘　　要：为解决致密储层开发中因非均质性造成的小层突进与平面舌进等问题,根据岩心、高压压汞、测井等资料,采用储层地质方法,从层内、层间与平面3个方面描述了合水地区Z183区块长7_(1)储层的宏观非均质性,并探讨其影响因素。结果表明,区块内存在2类层内夹层,其中泥质夹层分布相对较广。区块内可识别4类砂体构型,间隔叠加厚砂—薄泥互层型分布最广。区块内砂质碎屑流成因砂体分布范围最广。研究区储层整体具有强非均质性,其物性变化主要受砂质碎屑流微相与压实作用的影响。In order to solve the problem of small layer protrusion and plane protrusion caused by heterogeneity in tight reservoir development,according to the data of core,high pressure mercury injection and well logging,the macroscopic heterogeneity of Chang 7_(1) reservoir in Z183 block in Heshui area was described from three aspects of intra-layer,inter-layer and plane by using reservoir geological method,and its influencing factors were discussed.The results show that there are two types of interlayer in the block,and the distribution of the muddy interlayer is relatively wide.Four types of sand body configurations can be identified in the block,and the interbedded type of thick sand-thin mud superimposed at intervals is the most widely distributed.In the block,the genetic sand body of sandy debris flow has the widest distribution range.The whole reservoir in the study area has strong heterogeneity,and its physical property changes are mainly affected by the sandy debris flow microphase and compaction.
