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.
