Tongshen 1702 Well Sets A New Record Of 311.2 mm Borehole Daily Footage in The Block

Before drilling, the Suining Joint Project Department of Sichuan West Drilling Company and the Drilling Engineering Project Department of the External Blocks organized the technical backbones of the team and the relevant parties on site to compare and analyze the data of the neighboring wells in the Tongshen block, optimize the construction plan of this well, and strictly implement the relevant management requirements of Party A around how to speed up the Tongshen 1702 well.

During the actual drilling process, the 50656 team insisted on doing a good job in daily inspections of equipment, timely eliminating equipment hidden dangers, strictly implementing the maintenance regulations and equipment safety operating procedures for key equipment, and eliminating misoperation. With the strong support of the superior department, the team compared the lithological characteristics of each section of the formation according to the drilling design, conducted technical briefings on the risks downhole, and effectively improved the efficiency of drilling operations by optimizing the drill bit, optimizing the drilling tools, and optimizing the lean drilling speed-up template. The team adopted a fixed-person fixed-post method, implemented full-time on-site supervision and guidance by cadres, and timely adjusted the drilling pressure, top drive speed, and pump stroke to achieve the best drilling parameters, and made every effort to ensure safe and rapid drilling.
