大兴安岭中南段上古生界烃源岩地层的岩石物性特征
|
摘要
区域地层发育特征研究认为大兴安岭中南段上古生界具有较好的油气勘探前景,本次系统采集了扎鲁特盆地、突泉盆地、乌兰浩特地区的地层岩石物性标本,测试了密度及电阻率。结合前人物性研究资料与本次工作结果,系统地整理了扎鲁特盆地、突泉盆地、乌兰浩特地区地层岩石物性参数,重点分析了上古生界林西组地层的物性界面,为在该地区开展非震地球物理测量提供了基础性资料。从古地理环境和电阻率特征两个方面对比了三个地区的林西组烃源岩地层,认为突泉盆地地区形成烃源岩的条件相对有利,并且泥岩的板岩化程度低,是寻找林西组烃源岩最有利的地区。
Based on a study of regional stratigraphic development characteristics,the authors hold that the Upper Paleozoic in the central and southern part of the Da Hinggan Mountains has a good prospect for oil and gas exploration. In this study,stratigraphic physical specimens were systematically collected from Jarud basin,Tuquan basin and Ulanhot area,and density,magnetization and resistivity were analyzed. Combined with the previous character research data and the results of this work,the petrophysical parameters of the strata in Jarud basin,Tuquan basin and Ulanhot area were systematically sorted out,and the petrophysical interface of the strata in Linxi formation of the Upper Paleozoic was emphatically analyzed,thus providing basic data for the non-seismic geophysical survey in this area. A comparative study of two aspects of paleogeographic environment and physical characteristics shows that the hydrocarbon source rock strata of Linxi Formation in three areas are different. It is considered that the conditions for the formation of hydrocarbon source rock in Tuquan basin area are relatively favorable and,in addition,the degree of slatinization of mudstone is low,suggesting that this area is the most favorable area in the search for hydrocarbon source rock of Linxi Formation.
