摘要
塔河3号油田构造位置隶属塔里木盆地沙雅隆起中段阿克库勒西南部。奥陶系多次遭受不同程度风化剥蚀与淋滤作用,最终形成大型碳酸盐岩潜山,油气产于奥陶系溶蚀、裂缝性储集层中。根据溶蚀和裂缝发育段的岩芯观察特征、测井录井响应特征,定量提取反映岩溶和裂缝发育程度的控制特征参数,建立岩溶和裂缝发育程度和产能高低的分级判别标准,对该区6口探井奥陶系碳酸盐岩储层溶蚀缝洞发育层段进行了判识与含油气性评价。
Oil Field Tahe 3 is situated in the southwest of Akekule in the middle part of Shaya uplift, Tarim Basin. The Ordovician segments were eroded and leached in varying degrees many times. Finally they formed large carbonate buried hills, where oil and gas are found in corroded fissure reservoir. The (authors) analyse the core and logging response characteristics of corrosion and fissure segments, (quantitatively) extract the control characteristic parameters of karst and fissure growing degree, and (establish) the classifying standard in the paper. They also judge the eroded fracture segments of carbonate in the (Ordovician) reservoir and evaluate the hydrocarbon within them among 6 exploration wells in this area.
