Recently, from Drilling Company news came API 5DP Drill Pipe Pup Joint in Jidong Oilfield large displacement well np13-1706 well construction, the company can overcome the drill using manufactured nc52 high strength drill pipe, creating a level of drilling on land The maximum displacement of the new record. The well was drilled 6,387 meters deep, horizontal displacement of 4940.99 meters, breaking the Jidong Oilfield deepest depth, the horizontal displacement of the largest and deepest lower tail pipe deep well drilling and many other indicators.
Nc52 drill the use of high strength, as the first international and national patents, the company is for large displacement well drilling technical difficulties, combined with users and relevant research institutes jointly developed and produced. Compared with conventional drill pipe, with water can effectively reduce the loss of horsepower, a substantial increase in drilling efficiency; avoid failure in oversized drill pierced transitional drilling location; and a substantial increase in drill pipe fatigue life and other advantages. np13-1706 well drilling success, marking China's large displacement horizontal well drilling technology AISI 4142 Sucker rod to a new height, can also prove Bohai grams in the domestic first drill has mastered the core technology of production is suitable for large displacement drilling drill pipe technology.
