| 摘 要： | 为了更深入的研究电成像测井资料在储层评价方面的应用,针对碎屑岩、碳酸盐岩及薄互层三种类型的储层建立了三种新技术.通过对环井周电阻率数据进行统计,建立了电阻率谱技术及分选指数的计算方法,根据谱峰的宽窄及分选指数大小对碎屑岩储层分选性及非均质性进行评价,对于预测高产储层具有一定的指导意义;通过阿尔奇公式将环井周电阻率转换为孔隙度,并对孔隙度数据进行统计,建立了孔隙度谱技术及基质孔隙度及次生孔隙度的计算方法,对于评价碳酸盐岩储集层次生孔隙发育情况具有重要作用;利用电成像高分辨的优势,通过对薄互层电阻率进行统计,根据砂泥岩电阻率的差异,建立了薄互层有效厚度的计算方法,成为评价薄互层的一种重要手段.阐述了这些方法的基本原理及适应的岩性条件,拓展了电成像测井资料在储层评价方面的应用.

| Abstract: | There are three new technologies for the development of electric imaging logging in reservoir evaluation. Through the statistics of the circumferential well-resistivity data, a calculation method for the resistivity spectrum technology and the sorting index was established. Through the statistics of the circumferential resistivity data, the calculation methods of resistivity spectrum technology and sorting index were established. The classification and heterogeneity of the clastic reservoirs were performed according to the width of the peaks and the size of the sorting index. Evaluation has certain guiding significance for predicting high-yielding reservoirs. The Archie formula is used to convert the circumferential resistivity of the ring into porosity, and the porosity data are counted. The porosity spectroscopy technique, the method for calculating the porosity of the matrix and the secondary porosity are established to evaluate the carbonate reservoir. Secondary pore development plays an important role. Using the advantage of high resolution in electrical imaging, through the statistics of the thin interbed resistivity, according to the difference of the resistivity of shale and mud, a calculation method for the effective thickness of the thin interbed was established, which became an important means for evaluating thin interbeds. The basic principles of these methods and the suitable lithological conditions are described, and the application of electrical imaging logging data in reservoir evaluation is expanded. |
