摘要 高压低渗气藏成藏机制和分布规律与常规油气藏不同,地质响应特征特殊,造成综合解释评价结果与试油结果有偏差。文章从气藏高压异常原因和深层孔渗结构特性分析入手,结合高压低渗气藏在东濮凹陷的分布及地质录井显示特征,深入研究了识别高压低渗气藏的气测、轻烃等录井评价新方法,提出了如何综合利用录井技术来准确评价高压低渗气藏。 Forming mechanism and distributing rules of the gas accumulation with high-pressure and low-permeability are different from the common hydrocarbon reservoirs.Because of the special geological characteristics,the appraising result is not exactly same with the oil testing.By analyzing the reasons of the abnormal high-pressure and the characteristics of deep level osmose configuration,and associating with the distribution and geological mud logging characteristics of the high-pressure and low-permeability gas accumulation in Dongpu Depression,this paper researched how to distinguish the new mud logging evaluation method,such as gas chromatographic technique、light ends technique of the high-pressure and low-permeability gas accumulation.The paper provides a method to appraise the high-pressure and low-permeability gas accumulation correctly by using mud logging evaluation.
