摘要
方法利用古生物化石确定地层时代；通过岩石学研究，探讨潜山储层特征及影响因素。目的为曙先低潜山带的进一步勘探提供依据。结果曙103古潜山地层由上元古界青白口系和下古生界寒武系两个地层单元组成；储集空间为孔─缝型，整体上看曙103古潜山储层是由两个孔隙连通单元组成的复合块状油气藏，指出了角砾状云岩是最有利的储集岩。结论曙103古洛山在地层和储层方面取得了突破性认识，一是证明了辽河盆地内部有古生界存在，扩大了盆地内古潜山储层的勘探领域；二是为辽宁省区域地质研究提供了新资料。
Method Stratigraphic age is determined by paleontologic fossil. Through the study ofpetrology, buried hill reservoir characteristics and influencing factors are discussed. PurposeTo provide basis for further exploration of deep hurled hill reservoir of Shuguang area. Result Buried hill formation of Shu-103 consists of two stratigraphie units: Qingbaikou system of upper Proterozoic and Cambrian system of lower Paleozoic. Reservoir space is porecrevice type. From overall point of view, ancient buried hill reservoir of Shu-103 is a composite massive hydrocarbon reservoir consisted of two pore-connected units. It is pointed outthat breccia-shaped dolomite is the most favorable reservoir rock. Conclusion Further understanding has been acquired in terms of stratigraphy and reservoir for ancient buried hill ofShu-103 which includes that the proving of the exlstence of Paleozoic within Liaohe basinthat extends the exploration area for ancient buried hill reservoir and that the new information provided for regional geologlcal study of Liaoning Province.
