| Abstract: | There are complicated formation pressure system in Kekeya structure of southwest depression,Tarimu basin exploration well, Keshen 1 well with 6481 meters in depth,spuded in Dec. 1991,finished drilling in Aug. 1994 and was completion in Sep. 1994. This well is the one of deepest well,which drilled borehole of 444. 5mm in diarneter to 3544. 2m in depth,runing 339. 72mm of diameter casing into 3540. 93m,then drilled 311.15mm ddrieter borehole to 5028. 64 meters running 244. 5mm diameter into 5025. 68 meters nd ody drilled 215. 9mm diameter botehole to 6481 meters with coring 5. 32 meters that core recovery was 100% running combined liners of 177. 8mm and 139. 7mm diameter into 6479 meters in recent years. This paper introduce the drilling equipment and technology of Keshen 1 well. |
