Recently, 50.8 mm "large-diameter, high-strength, and ultra-long" coiled tubing jointly developed by Bohai Drilling Downhole Operation Co., Ltd. and Yantai Jereh Co., Ltd. was successfully completed by dragging the acid in the depth of 6010 meters below the Xinyi 7 well in the Tarim Oilfield. Success, creating a deep world record with large diameter coiled tubing.
Due to the deepness of the Tarim well, the coiled tubing used in the past was of small size, with a depth of less than 4,000 meters, and the operating range was only gas lift. Bohai Drilling Downhole Operation Company developed large diameter coiled tubing based on the technical requirements for oil and gas exploration in deep wells and ultra-deep wells in the Tarim Oilfield, and reached a strategic cooperation agreement with Baker Petroleum Tool Services to provide technical support for coiled tubing on-site application.
