巴特肯4油组储层四性特征分析

Analysis of the reservoir four characteristics for the fourth oil line in Batken

巴特肯4油组储层岩性主要为石英砂岩,粘土矿物主要为伊利石,胶结物为粘土矿物和碳酸盐岩,物性相对较好,以中低孔低渗为主,含油层电阻率一般在50Ω·m以上,原始含有饱和度高,含油级别以油侵和油斑为主,流体性质以油水混储为主且无明显的油水界面。

The reservoir lithology for the fourth oil line in Batken is mainly quartz sandstone,clay minerals are mainly Illite,and the cements are clay minerals and carbonate rocks,thus whose physical properties are relatively excellent,that are the main characteristic is low porosity and low permeability,the resistivity of oil layer is generally greater than50Ω·m,the original containing saturation is high,the oil level is mainly the oil penetration and oil stains,and the fluid property is mainly the mixture of oil and water,and have no obvious oil-water interface.
