Controlling Factors on Physical Property and Reservoir Characters of Fengcheng Formation in Shawan Depression, Junggar Basin
-
摘要:
为进一步挖掘沙湾凹陷风城组油气勘探开发潜力，需要针对储层基本特征以及物性控制因素进行详细研究。通过岩心观察、薄片分析等多种研究手段，分析储层特征以及物性控制因素，为优质储层的预测奠定基础。结果表明，风城组储集岩性以砂砾岩为主，储集空间以微裂缝为主，普遍见片状片弯状喉道，孔隙结构较差，属于特低孔特低渗储层。构造、沉积和成岩作用为储层物性主要控制因素，断裂的发育以及异常压力的形成为微裂缝的发育提供基础条件，古地貌对沉积水动力条件起到重要控制作用，岩石成分和结构差异加剧储层物性平面的非均质性。成岩作用控制储层最终物性，压实和胶结作用造成储层物性变差，溶蚀作用的发育极大改善储层的物性。研究区北部凹槽内断裂带附近的风城组砂岩类储层为下一步勘探的重点目标。
Abstract:It is important to search controlling factors on physical property and reservoir characters of Fengcheng Formation in Shawan depression, where need to excavate large oil and gas potential. Petrology, reserve characters and controlling factors on physical property of Fengcheng Formation were analysesed in detail through core observation, microscope image analysis, SEM, electro probe micro-analysis, physical property and oil testing data. Rock type of Fengcheng Formation was dominated by sandy conglomerate, and micro cracks were main reserve spaces with bending throats; The reservoir belonged to low porosity and low permeability with complex pore structures; Tectonic, sedimentary and diagenetic were controlling factors on physical property, development of faults and abnormal pressure built basic formation for micro cracks, ancient landscape had an important control on hydrodynamic conditions, differences on composition and construction of rocks intensified plane heterogeneity of physical property. Diagenetic controlled final physical property, compaction and cementation made physical property of reservoirs poorer, while corrosion made it better.
