欧利坨子地区位于辽河盆地东部凹陷的中段,为坳陷内始新世岩浆活动中心。在对该地区火山岩发育年代、岩石类型、喷发模式及火山口位置等研究的基础上,选取沙三段Ⅱ组粗面岩为研究对象,将储集空间划分为五种类型,应用“宏观”统计和常规测试两种方法对孔隙度进行了定量计算,并建立了火山岩岩性和储层评价的测井响应标准,确认本区火山岩油气藏受构造和岩性双重困素的控制。 The Oili Tuozi area is located in the middle of the eastern sag of the Liaohe Basin and is the Eocene magmatic activity center of the depression. Based on the research on volcanic age, rock type, eruption pattern and crater location in this area, the Group Ⅱ is selected as the research object, the reservoir space is divided into five types, the application of “macro” Statistics and routine tests were used to quantitatively calculate the porosity. Well logging response criteria of volcanic lithology and reservoir evaluation were established to confirm that the volcanic reservoirs in this area are under the control of both structural and lithological double factors.
