The Great Wall drilling directional integrated service obvious advantages
China Petroleum Network News (reporter Dong Xuxia) August 1st, by the the Great Wall drilling service Jidong Oil Field Liu 10-32 wells are ready to put into production. The actual construction period of the well is 28 days, 9 days ahead of the design period. The directional integration technology service of the Great Wall drilling engineering company is providing a new way to increase drilling speed.
Directional integrated service is a kind of service pattern that the Great Wall drilling aims at setting up the directional drilling speed. After years of technical research and accumulation, the Great Wall drilling has a number of independent intellectual property equipment including wireless MWD (LWD) and PDC drills.
The Great Wall drilling technology breakthrough the limitation of original service, according to its own technical highlights and overall technical advantages, innovative technology services, by providing technical services including drilling trajectory control service, PDC service, bit pressure control drilling service and optimize the allocation of resources and tools, screw speed, drilling speed, shorten the drilling cycle to achieve the purpose of.
The core of directional integration service is to use professional team to tailor personalized service plan. In the service process, site engineers with adjacent wells data and actual drilling condition, timely analysis and prediction of drilling tendency, optimizing the trajectory, to ensure the well trajectory and greatly reduce sliding drilling ratio, greatly improve the construction speed. In the PDC bit service, the Great Wall drilling through personalized design and optimization of drilling bit, drilling speed, and effectively reduce production costs. In September 2016, through the drill bit optimization, the Great Wall drilling in Su 53-66-36H well implementation of vertical section of a drill bit, a drill guide hole, two bit oriented section and horizontal section of a drill bit break mode is the group's proposed 1+2+2 saves a bit.
Since 2016, the Great Wall drilling launched integrated technical services, has achieved significant acceleration effect. A new breakthrough in the implementation of 268-H313 wells in Liaohe oil province Shen horizontal section full rotary drilling; in Su 53-70-43H well to complete drilling directional section, reduce drilling time for 200 hours; 6 days earlier drilled 15 wells in the flat area of Hailar and 3-, created the fastest construction record, and the drilling rate reached 95%. At present, this model has been extended to many markets at home and abroad.
