Three mobile red flags for high-efficiency construction in western North China

News from Sinopec News Network, "This is the first time in our well team that we have won the mobile red flag for three consecutive months.

Since the beginning of this year, in the face of the severe production and operation situation, the 90103 well team of North China Petroleum Engineering Company West Branch has strengthened on-site safety management, adopted new technologies and new processes, and strengthened cost control.

New technology improves timeliness

Shunbei 4-1H well is an ultra-deep horizontal well deployed by a group company in the Shunbei Oilfield.

The company provided F2200 high-pressure pumps, 1100 kilowatt generator sets, 5-unit high-frequency vibrating screens and supporting electronic control systems for the 90103 well team, laying a solid foundation for the speed and efficiency of drilling operations.

During the drilling of the two-way long open hole section, the company optimized the anti-collapse and plugging performance of the drilling fluid to maintain the stability of the Permian igneous rock and Silurian well wall; preferentially shaped tooth PDC bit and high torque screw drill through the Permian system With other measures, three drilling trips completed the drilling construction task of the well section, which was 100.

Faced with the geological problems of high lithological hardness and poor drillability during drilling in the third section of Shunbei 4-1H Well.

Fine management and cost control

During the on-site construction, the employees of the 90103 well team cut and assembled the waste mud medicine barrels and processed them into blowout prevention boxes for use in drilling operations; they also used waste tarpaulins as oxygen and acetylene bottles, and processed sunscreen devices to ensure safe production.

　　"Benefits are squeezed out from the drip.

　　They also strengthened the analysis of adjacent well data, strictly controlled operations, guaranteed downhole safety, avoided downhole complexity due to operational errors or human factors, and further reduced the cost of oil, drill bits, and mud materials.

　　At the same time, the team organizes production and technical backbones, and trains the team staff by type of work and position, so as to improve the staff's sense of responsibility for equipment maintenance and the ability to judge equipment hidden dangers.

　　A solid foundation for safety management

　　"I was in the wrong position at the head of the well when I tripped.

　　Every time during special operations such as casing running and wellhead replacement during drilling construction, the company will organize production technology, mud, safety and environmental protection experts to guide the well to ensure stable and orderly safe production on site.

　　At the same time, the team strictly manages the standardization of HSSE indoor data, adopts the "regional management position system" on site, refines the responsibilities of cadres and follow-ups, strengthens on-site inspections, implements safety responsibilities, and creates a standardized operation site.
