Bohai Drilling Drilling Company 4 focuses on analyzing the lithology characteristics of each block and vigorously promotes the application of PDC+ screw composite drilling technology. As of November 15, 80% of the company's wells have adopted this technology, and the single-well drilling technical indicators in multiple blocks have reached new highs, realizing the refined development of composite drilling technology.
Composite drilling is a cutting edge drilling technology developed in the 1990s. The application can complete the construction of the upper straight section, the inclined section, the stable inclined section and the descending inclined section in one operation, which is beneficial to increase the drilling speed and reduce the number of times of drilling.
Drilling Four Company has made it the main research goal to improve the well trajectory control level, speed up the drilling speed and reduce the comprehensive cost of drilling. It is better to optimize the PDC bit type, reasonably match the drilling structure, and properly match the drilling parameters and hydraulic parameters.
This year, the company optimized its technology and the drilling speed-up effect was obvious. In the Yanlan block, two well groups drilled 12 wells with a footage of 37,900 meters. The average monthly drilling speed was 5,984 meters per piece, and the average mechanical drilling rate was 27 meters per hour, up 25.6% and 14.7% respectively. At the same time, the company's production and operation quality has been greatly improved. In the first 10 months of this year, the timeliness and complex aging time of drilling accidents were only 0.2% and 0.66%, a record low.
