Bohai Drilling Company is closely focused on accelerating the construction of a world-class international oil service enterprise, and regards the vigorous promotion of the "one trip drilling" project as an important lever for speeding up and improving efficiency. It continuously improves the combination of "one trip drilling" characteristic technologies and construction plans for different regions, formations, and well sections, and summarizes and promotes the best operational practices of "one trip drilling". In the first half of this year, Bohai Drilling completed 232 drilling operations at depths of over 2000 meters in various markets, accounting for 42.34% of the total.
Fine Production Organization
Steadily advancing the 'one trip drill'
One trip drilling "refers to a drill bit that completes one opening or section of the well in one go, achieving the goal of shortening the construction period and improving quality and efficiency. Implementing 'one trip drilling' is a systematic project that requires not only advanced and efficient technology, but also collaboration among teams. In response to this, Bohai Drilling Company has started with top-level design, forming a top-down linkage and joint management mechanism with leaders taking the lead, production and technology departments leading, administrative logistics support, and frontline teams implementing. Together, they have formulated a "one trip drilling" implementation plan and steadily promoted the implementation of the "one trip drilling" results.
For wells that can implement the "one trip drilling" project, Bohai Drilling follows the "four requirements" model, which includes "detailed preparation of each process, reasonable work steps, advanced material planning, and meeting work quality standards". It deepens the lean drilling production organization, refines the opening connection from multiple dimensions, quantifies the time of each process, minimizes auxiliary operation time, and forms a set of efficient production organization and smooth process connection work modes.
In the construction of the JHW82-32 shale oil well in Jiqing, Bohai Drilling's various construction units finely organized production, highlighted advanced and rigorous methods, communicated and coordinated with cooperating parties in advance to speed up tools, ensured ground equipment support, and maximized production efficiency, achieving the goal of "two drilling and horizontal sections" and "one drilling" completion, setting two records for the shortest drilling cycle and completion cycle of oil wells deeper than 5500 meters in the Jiqing market.
Strive for excellence in technology
Assist in the implementation of 'One Trip Drilling'
Since the beginning of this year, the Bohai Drilling "One Trip Drilling" project has continuously made new breakthroughs, and the technical research team has played an indispensable role. High quality and efficient drill bits are powerful tools for achieving 'one trip drilling'. The combination of drilling tools, the use of tools and instruments, the selection of drilling parameters, the optimization of drilling fluid system performance, and the control of wellbore trajectory are all important factors in assisting 'one trip drilling', "said Chen Tian, a technician at Bohai Drilling Company
According to the concept of "one well, one strategy, one section, one method, and one layer, one move", Bohai Drilling arranged technical experts to provide on-site guidance, starting from geological characteristics, process measures, etc., taking profiles, targets, and actual drilling trajectories as research objects, analyzing the differences between completing wells with "one trip" and combining with the actual construction of single wells and blocks, continuously refining drilling pressure, pump pressure, and displacement
