由于碳酸盐岩储集层的双重孔结构与裂缝发育非均质的特点,单纯使用含水饱和度参数划分气水层是有一定局限性的。通过毛细管压力对储层含水饱和度影响的究研,结合地质及测试等资料,由实际地层条件及资料出发,究研了用Φ～Sw双曲线法、P~(1/2)正态分布法,视地层水电阻率Rwa法综合解释,相互印证来判别气水层的方法。这种综合分析方法得到了一些实际资料的印证。当然,这只是在目前的测井系列化、标准化不够完善的条件下所进行的初步研究,尚属探讨性质,谨此作为抛砖引玉,(不包括那些以裂缝为主,孔隙度小于
Due to the heterogeneity of the dual pore structure and fractures of carbonate reservoirs, the division of gas-water layer by simply using water saturation parameters has some limitations. Based on the study of the effect of capillary pressure on the water saturation of reservoirs and the geology and test data, the actual stratigraphic conditions and data are used to study the normal distribution of P ~ (1/2) with Φ ~ Sw hyperbolic method Method, depending on the formation water resistivity Rwa method comprehensive interpretation, mutual confirmation to determine gas and water layer method. This comprehensive analysis has been confirmed by some actual data. Of course, this is only a preliminary study carried out under the current well-logging serialization and standardization imperfections. It is still a discussion of the nature and is hereby intended to serve as a valuable guide (excluding those mainly fractures, with less than
