油气地质异常与非传统油气资源勘探研究

OIL GEOLOGIC ANOMALY AND NON-TRADITIONAL PETROLEUM RESOURCE EXPLORATION RESEARCH

针对资源勘查难度增加的实际问题 ,提出了油气地质异常的新概念 ,阐述了各类油气地质异常及其成因 ,认为油气地质异常主要包括 4类 :沉积异常、构造异常、地球化学异常和地层压力异常 ;油气地质异常的分布范围分 4级 :区带油气地质异常、圈闭油气地质异常、小型油气地质异常和微型油气地质异常 ;并阐述了非传统油气异常定量研究思路和方法。

Dealing with the actual problems of hard to find more natural resources, a new concept of oil geologic anomaly is brought forward in this article. Oil geologic anomalies include four types which are sedimentary anomaly, tectonic anomaly, geochemistry anomaly, strata pressure anomaly. Their distributing ranges may be separated to four ranks that include region-oil geologic anomaly, enclose-oil geologic anomaly, minitype-oil geologic anomaly, microscope-oil geologic anomaly. The method of studying on nontraditional oil geologic anomaly is also summarized.
