川中地区油气藏综合化探异常模式研究

STUDY OF ANOMALY MODELS OF COMPREHENSIVE GEOCHEMICAL EXPLORATION IN CENTER SICHUAN OIL AND GAS RESERVIORS

总结了川中地区的油气藏综合化探异常模式类型及与油气藏类型的对应关系 ,并运用水平分异理论推演了随油气藏储量在不同历史阶段其油气化探综合异常模式所发生的相应变化。油气藏综合化探异常模式对油气藏类型及物性具有良好指示作用 ,可根据油气藏的综合化探异常模式进行地质反演 ,从而对所在地区的油气远景进行预测。

WT5BZ]A summarization has been made for the anomaly models of compreehnsive geochemical exploration and its relationship with oil and Gas reservoirs types in the oil and gas reserviors in center sichuan. It is deduced with the theory of horizontal differention for the coincident change of the anomaly models of comprehensive geochemical exploration with the oil and gas reservoirs in various historical stages. The comprehensive geochemial exploration anomaly models of the oil and gas reservoirs show a good indication for the type of the oil and gas reservoirs and its physical characters. The geological deduction can be made according to the comprehensive geochemical exploration anomaly models, which then can be used to make prediction of the prospective of oil and gas in the district.
