Construction of 2-1 Salt Well in Ningjin-Xinji Exploration Area

Abstract:

Due to the core drilling depth increasing with more auxiliary work time, improvement of round trip efficiency is imperative. Without large scale of drilling equipments renewal, according to the difficulties in salt rock coring in Ningjin-Xinji exploration area, the supporting research was made on optimization of well program, rapid drilling in non coring section, salt water drilling fluid system and safe coring in salt rock layer, which was successfully applied in the field practice.
