摘要
通过对塔河油田托甫台地区200余口井的常规测井、成像测井及钻井录井和生产试油等资料的综合分析,以及对该区奥陶系储层特征和类型的研究,认为区内奥陶系一间房组储层基质孔隙度较低,溶蚀孔、洞和裂缝是主要储集空间。结合该区构造特征和断裂发育特征,总结出该区储层类型受断裂控制,平面上呈"南北分级、东西分异"特点,同时,油气充注受断裂控制,不同断裂条带,油气藏表现特征不同。
In this study,we analyzed more than 200 data of the well in the tuofutai region of the Tahe oilfield,These data include the conventional log,the imaging logging,drilling,geological logging,producting,testing and so on.By analyzing reservoir characteristics and type of the Ordovician,we believe that dissolution pores, holes and cracks are the main reser-voir space in study area,however,the matrix porosity is small.Combined with the structural and fracture characteristics of the region,we summed up the faults control the development of reservoir types,and show the feature of“South grading, something differentiation”.Meanwhile,oil and gas injection has also been controled and influenced by the fracture,it showing strips of different faults,which exhibit different reservoir characteristics.
