川东石炭系流体性质的测井响应特征与判别方法

针对碳酸盐岩储层含流体性质相同而测井特征不同，从而造成对储层含流体性质的误判问题，开展了专题研究。研究中对实钻井的测井、试油和岩心分析资料进行对比分析，最终认识到储层孔隙类型的差别是影响储层含流体性质的测井特征响应不同的主要原因，误判层主要发生在以晶间孔为主的储层。在此基础上，建立了判断储层孔隙类型并结合孔隙度-电阻率交会图判断储层含流体性质的方法。所提出的方法，可以有效解决测井误判油气水层的问题，从而提高测井解释储层含流体性质的符合率。

LOGGING RESPONSE CHARACTERISTICS AND DISCRIMINANT METHOD OF CARBONIFEROUS FLUID PROPERTIES IN EAST SICHUAN BASIN

The research was developed particularly for the misjudgement of reservoir fluid properties caused by the fact that the fluid in the carbonate reservoir has same properties but different logging characteristics. Analyzing well log, well testing, and the core data, this paper discovered that the difference among pore types in the reservoirs is the main reason that the different logging response characteristics existed in the fluid with the same properties, and the misjudgement occurred mainly in the intercrystal pore reservoir. On this basis, this paper established a method which could be used for judging the pore type and the reservoir fluid properties combined with porosity/resistivity intersection. And this method could also be used for resolving the problems of judging oil gas water layers by well logging, thereby to increase the accuracy of fluid properties interpreted by well logging.
