松辽盆地德惠凹陷深层含油气系统划分
|
摘要
近年来 ,含油气系统的概念受到了人们的广泛关注 ,它为油气勘探提供了一种新的研究方法。作者在对松辽盆地德惠凹陷烃源岩有机质热演化剖面研究以及对工区钻井、测井、地震及分析测试资料进行全面收集和整理的基础上 ,开展了生、排烃史的动态模拟。依据有机包裹体拉曼光谱分析、油气源对比及异常地层压力 ,德惠凹陷深层剖面上初步可划分出 2个含油气系统 :a)下部自源含油气系统 ,以营城组顶部异常压力界面或不整合面为界 ;b)上部它源含油气系统 ,以泉三顶部异常压力面为界。平面上可划分农安、鲍家和布海 3个亚含油气系统。其中农安亚含油气系统是最有利的含油气系统 ,鲍家亚含油气系统是次有利含油气系统 ,布海亚含油气系统是第三有利含油气系统。另外 ,还指出了其中的不足
In recent years, the concept of petroleum systems has got wide attention. It provides a new research method for hydrocarbon exploration. Based on the thermal evolution profile stuey of organic matter in the hydrocarbon source rock of the Dehui Depression in the Songliao Basin and the thorough collection and collation of drilling, logging, seismic and testing data from the working area, the history of hydrocarbon generation and expulsion was dynamically simulated. According to the laser Raman spectrum analysis of organic inclusions, the correlation of hydrocarbon sources and the abnormal pressure of the strata, the Dehui Depression can preliminarily be divided into two petroleum systems on the deep profile, that is, the lower self sourced petroleum system which is bounded by the abnormal pressure interface or unconformity plane on the top of the Yingcheng Formation and the upper else sourced petroleum system which is bounded by the abnormal pressure surface on the top of the Quansan Formation. On the plane, Nongan, Baojia and Buhai three petroleum subsystems were divided. Among them, Nongan petroleum subsystem is the most favorable one, Baojia petroleum subsystem is the second, and Buhai petroleum subsystem takes the third. Otherwise, the lack of the method was pointed out.
