The Yanxie 229 well is an evaluation well deployed in the steep slope tectonic belt of the Dongying Sag in the Jiyang Depression in the northern part of the Adongying Sag. It is drilled by the 50107 team of the Yellow River Drilling Company. The target layer is glutenite and the formation can be drilled. Very low. In order to do the drill bit support, the drilling technicians designed and developed a new steel body diamond PK6257SJD-215.9 drill bit for the lithology characteristics of the formation. The drill bit adopts special cloth tooth design and encryption technology, and selects high-performance cutting teeth. Excellent grinding and impact resistance. The drill bit was drilled from 3,564 meters in the fourth section of the sand, 3,840 meters, and the footage was 276 meters. The drill bit was 3.17 times the footage of a roller cone drill on the same well.
