摘要
针对M油田Z10储层砂体发育规律以及油砂体分布不明确等问题,综合利用取芯、测井、试油试采等资料,基于储层单砂体进行储层四性关系分析,确定油砂体的下限标准,从而进行预测。研究结果表明:油砂体下限标准:储层岩性下限为粉砂岩,物性下限为:孔隙度为8.5%,渗透率为5.31 mD,电性下限为Sw小于0.65,Rt大于2Ω·m,AC大于238μs/m,油砂体主要在主力层发育,展布形态不规则,与砂厚分布有很好的一致性,通过研究,可对类似油藏油砂体进行分布规律预测,研究成果可为油田滚动开发提供地质依据。
Aiming at the problems of sand body development law and unclear distribution of oil sand body in Z10 reservoir of M oilfield,the lower limit standard of oil sand body is determined by comprehensively using the data of coring,logging,oil production test and so on,based on the analysis of the relationship of four reservoir properties of single sand body,so as to predict.The results show that:the lower limit standard of oil sand body:the lower limit of reservoir lithology is siltstone,the lower limit of physical property is porosity is 8.5%,permeability is 5.31 mD,the lower limit of electrical property is Sw less than 0.65,Rt greater than 2Ω·m,AC greater than 238μs/m.The oil sand body is mainly developed in the main layer with irregular distribution,which is consistent with the distribution of sand thickness.Through the research,the distribution law of oil sand body in similar reservoirs can be predicted,and the research results can provide geological basis for the rolling development of the oilfield.
