××潜山基岩是一套中上元古界的海相碳酸盐岩及滨海碎屑岩地层,具有构造复杂,裂缝发育的特点。以往在对该储层进行研究时,没有形成一套多学科结合的综合研究方法,因此在对储层评价时,缺乏全面的统一标准。本文基于“四性分析法”,即储层的岩性、物性、电性及含油性,从基岩岩石学解析及成岩作用分析出发,建立潜山基岩地质特征及潜山储层发育的地质理论模型,结合基岩储层的测井特征以及生产试油资料,对潜山基岩储层进行评价,取得了良好的效果。“四性分析法”充分利用了有限的资料,建立一种适用于潜山海相碳酸盐岩裂缝-溶蚀孔洞型储层的评价方法。
× × buried hill bedrock is a middle-upper Proterozoic marine carbonate and coastal clastic rock strata, which has the characteristics of complex structure and fractured development. In the past, no comprehensive and multidisciplinary research method has been developed for the study of the reservoir. Therefore, there is a lack of a comprehensive uniform standard for reservoir evaluation. Based on the “four-attribute analysis method”, that is, lithology, physical property, electrical property and oiliness of reservoirs, from the petrological analysis and diagenesis analysis of bedrock, the geological characteristics of buried hill basement and the development of buried hill reservoir Geological theory model, combined with the logging characteristics of bedrock reservoirs and oil production test data, the buried hill reservoir evaluation, and achieved good results. The “four-attribute analysis method” makes full use of the limited data to establish a method suitable for evaluation of fractured-eroded pore reservoirs of carbonate rocks in buried hills.
