前人对研究区致密砂岩的四性关系研究比较薄弱,测井解释精度不高等问题比较突出。基于此,本文详细分析了研究区的取心井的岩性、物性、含气性和电性等特征及其之间的关系,采用岩心刻度分析、录井分析以及试气资料刻度测井的方法,细致分析了Y气田致密砂岩储层四性关系,在此基础上,以电性特征为参照,分别讨论了储层岩性、物性及含气性的电性响应特征。从而为评价和筛选有利储层,提高测井解释精度等提供合理的地质依据和技术支持。
Previous studies on the relationship between the four types of tight sandstone in the study area are relatively weak, and logging interpretation accuracy is not high. Based on this, this paper analyzes in detail the lithology, physical properties, gas-bearing and electrical properties of coring wells in the study area and their relations. The core scale analysis, logging analysis and test gas logging Method, the four-dimensional relationship of tight sandstone reservoirs in Y gas field has been carefully analyzed. On the basis of this, the electrical response characteristics of lithology, physical property and gas-bearing property of reservoirs have been discussed with reference to electrical characteristics. Which will provide reasonable geological basis and technical support for the evaluation and screening of favorable reservoirs and improvement of logging interpretation accuracy.
