Abstract

Every year, the percentage of development of complex and unconventional hydrocarbon reservoirs is increasing, which is associated with the depletion of traditional oil and gas reserves. Carbonate reservoirs are hard-to-recover reservoir rocks due to the high degree of heterogeneity. A more detailed study of the lithological features and physical properties of carbonate rocks is an important and integral part of the complex reservoirs development. In the present work has done a comprehensive analysis of the lithological and geomechanical properties of the Middle Carboniferous strata deposits of the Dachnoye oil field, located in the southeast of the Republic of Tatarstan. The main attention in the research was focused on the estimation of the britleness of rocks. Britleness index is necessary for correct prediction of hydraulic fracturing. The result of the research is the identification of carbonate facies and their geomechanical characteristics, as well as the estimation of the britleness of rocks by various methods.
评估鞑靼斯坦共和国巴什基尔碳酸盐岩的地质力学特性以优化水力压裂法
随着传统油气储量的枯竭,复杂和非常规油气藏的开发比例逐年增加。碳酸盐岩储层因其高度的异质性而成为难以开采的储层岩石。对碳酸盐岩的岩性特征和物理性质进行更详细的研究,是复杂储层开发不可或缺的重要环节。本研究对位于鞑靼斯坦共和国东南部的达赫诺耶(Dachnoye)油田中石炭纪地层矿床的岩性和地质力学性质进行了全面分析。研究的主要重点是对岩石脆性的估算。岩石脆性指数是正确预测水力压裂的必要条件。研究成果包括确定碳酸盐岩层及其地质力学特征,以及通过各种方法估算岩石的脆性。
