碳酸盐低潜山优质储层测井识别方法

Logging Identification Method of Carbonate Low Buried Hill Reservoir

随着勘探的逐渐深入,潜山油气藏以及深层领域勘探将占有愈加重要的地位。碳酸盐岩作为油气藏的重要储集层,蕴藏着非常丰富的油气资源。对于潜山碳酸盐储层特征研究而言,潜山碳酸盐储层的岩性识别是十分重要的,针对潜山的勘探现状,吸收总结前人的成果,分析S区块潜山油藏特征。利用岩心录井资料和测井资料绘制出多组储层岩性识别交会图版,提出乘积交会图版,并对图版进行验证,选择出最优的识别图版为乘积识别图版。

With the constant development of the exploration, exploration of oil and gas reservoirs in buried hill and deep field will play an important role. As an important reservoir of oil and gas, the carbonate rock has abundant oil and gas resources. It is very important to identify the lithology of the carbonate reservoir in buried hill. Aimed at the exploration status of the buried hill, based on predecessor’s research results, features of buried hill oil reservoirs in S block were analyzed. Sets of reservoir lithology crossplots were drawn by using core data and logging data, and product crossplot was proposed. The crossplots were validated to select the best identification crossplot as the product crossplot.
