"What is the pressure rating of the wellhead blowout prevention system required for normal pressure well testing?" On August 1, Song Aidong, safety supervisor of the Northwest Oilfield Completion Test Management Center, conducted a test on the construction site of Huapeng at the construction site of Well TH12264.
Du Fagang, the oil team, conducted a well control knowledge assessment to check that the contractor’s employees were familiar with the well control knowledge
.
The Northwest Oilfield has the characteristics of "two supers and five highs" reservoirs, and the completion test operation is highly risky and difficult to operate
.
On the basis of summarizing the existing management experience and combining the characteristics of the completion test operation, the Completion Test Management Center innovated the completion test management system with "full process" management and control as the core, and achieved comprehensive improvement of corporate safety through "full process" management and control.
The “full process” management and control covers 7 majors including wellbore operations, formation testing, oil testing, gas lift, perforation, well testing and production logging in the completion and oil testing phase, 46 processes, 409 important management points and 1739 management Standard
.
Enter the completion test stage, according to the risk level of the construction well, arrange the corresponding level of project management personnel to find out the key equipment, personnel, and well conditions on the site, and coordinate and prepare for the subsequent construction work.
During the construction process, the management personnel will ask questions Carry out acceptance inspections on the contractor’s on-site staff, examine the construction personnel’s understanding of personal job responsibilities, job risks, and preventive measures.
At the same time, the entire process of control from tool and equipment testing, design review, start-up acceptance, process monitoring to construction assessment is realized.
"Man, machine, material, law, environment" and "planning, organization, coordination, control, supervision" and other processes are controlled according to the principle of "one well, one design, one team, one strategy, one well, one strategy, and one section, one measure" , Adopt a modular and process-based approach to control key decision points and checklists to achieve "full process" management and control of construction operations, and effectively ensure the safety and quality level of completion testing operations
.
Through "full process" management and control, uniform construction standards and management standards, reduce various construction risks from the source, stabilize the overall construction capabilities of the professional team, achieve scientific, standardized, and refined on-site management, comprehensively improve the safety and quality level, and ensure on-site construction Safe, high quality and efficient
.
It has formed a domestic industry-leading management system, which is creative, practical and popular
According to statistics, the number of field problems found in the first half of 2021 decreased by 23.
6% compared with the same period in 2020, and the one-time success rate of completion operations remained 100% for three consecutive years.
As of August 1, the completion test management center has achieved 4386 continuous safe production.
