塔河油田托普台区碳酸盐岩储层类型判别方法及应用

Identification of Carbonate Reservoir Types in Tahe Oil Field of Tuoputai Region and Its Application

碳酸盐岩储层类型的测井解释评价难度很大,利用常规测井信息构建能够反映碳酸盐岩储层孔、洞和裂缝特征的导电效率、孔隙度、裂缝孔隙度、深电阻率减小幅度四个参数作为划分储层类型的参数,通过对39口井153层不同类型的储层进行参数统计,确定了塔河油田托普台区碳酸盐岩储层类型的判别标准,经过2011年4口新井15层的成像测井资料验证,认为采用导电效率等参数来判别碳酸盐岩储层类型是可行的,与地质研究划分储层类型吻合程度较高,使常规测井资料得到了创新应用。

It is very difficult to evaluate well logging interpretation for the types of carbonate reservoir.In this paper,the conventional logging information is used to construct parameters such as conductive efficiency,porosity,fracture porosity,decrease of deep resistivity,which can be used to detect the fractures and caves of carbonate formation.By processing 153 reservoirs from 39 wells containing different reservoir types,identification standard of reservoir type is built.15 layers with imaging logging data from 4 wells are used to test the identification standard,and the result indicates that the parameters（conductive efficiency,porosity,fracture porosity,decrease of deep resistivity） is good at discriminating the carbonate reservoir types,in which the conventional logging data are applied in an innovative way.
