伊斜167井位于吉尔吉斯共和国中西部贾拉拉巴德州马义里苏市东南方,费尔干纳盆地的东北部,地面海拔一般在800-1500米,地势以中低丘陵为主。其地层沉积为陆相沉积中的古河道沉积,沉积岩以碎屑岩和粘土岩为主,其岩石类型为泥岩、砂岩、砾岩组成,层理类型多样;地层组成及岩性特点较为复杂,在该地层定向井的施工对钻井液的体系及各项性能参数提出了更高的要求。采用强抑制聚合醇润滑防塌钻井液体系,完满完成该井的钻井施工。
Well 167 is located in the southeastern Ma Li Lisu, Jalalabad prefecture in the central and western Kyrgyz Republic, the northeast of the Fergana basin, the ground elevation is generally 800-1500 meters, the main low-lying terrain. The stratigraphic sediments are the sediments of ancient rivers in continental deposition. Sedimentary rocks are mainly clastic rocks and clay rocks. The rock types are composed of mudstone, sandstone and conglomerate with various types of bedding. The stratigraphic composition and lithology are complex, Directional wells in the formation of the drilling fluid system and the performance parameters put forward higher requirements. The use of strong inhibition of polymerization alcohol lubrication anti-collapse drilling fluid system, the successful completion of the well drilling.
