摘要:
岩性识别与解释是油气储层表征的基础,对有利层位预测具有重要意义。四川盆地永川地区上二叠统龙潭组为典型的海陆过渡相沉积,主要发育陆源碎屑夹碳酸盐岩含煤层系,岩性多,纵向变化大,测井识别难度大。基于钻井岩心观察、常规测井及地质数据统计理论,建立一种针对复杂岩性的定性+半定量+定量的测井识别方法,即在地质岩心刻度常规测井基础上,运用交会图法、蛛网法半定量地分析提取各岩性电测曲线响应特征,再利用多参数概率因子法对岩性进行定量识别,结果与录井岩性剖面、取心岩性剖面的吻合率分别为89.9%和91.31%。所建立的复杂岩性测井识别方法具有一定的推广性。
Abstract:
Lithology identification and interpretation is the basis of oil and gas reservoir characterization, and is of great significance for favorable formation prediction. The Upper Permian Longtan Formation in the Yongchuan area of the Sichuan Basin is a typical marine and continental transitional deposit, mainly developing a coal-bearing formation system of terrigenous clastic interbedded carbonate rocks, with many lithologies and large vertical variations, making logging identification difficult. Based on drilling core observation, conventional logging, and geological data statistical theory, a qualitative to quantitative logging identification method is established for complex lithologies, that is, based on conventional logging with geological core scale, the response characteristics of each lithology electrical logging curve are analyzed and extracted by using cross plot method and cobweb method in a semi-quantitative manner, and then the lithology is identified quantitatively by using multi-parameter probability factor method. The results are in agreement with 89.9% and 91.31% of the logging lithology profile and core lithology profile, respectively. The complex lithology logging identification method established in this paper has a certain degree of applicability.
