1806 Meters! Western Drilling Hits New Milestone in Drilling Day Progress
Apr 10, 2024
On April 5, the full-depth 3-H13 well drilled by the 80005 drilling team of the Bazhou Branch of China National Petroleum Corporation Western Drilling Engineering Co., Ltd. broke the record for the highest single-day footage in the Tarim Oilfield with a single-day footage of 1,806 meters. Compared with the record in the same block, it has increased by 152%, achieving a historic improvement from "1 kilometer per day" to "1 mile per day (1 mile = 1609.344 meters)".

The design depth of Well Manshen 3-H13 is 8698.29 meters. In response to geological conditions such as the upper strata in the Fuman block of the Tarim Oilfield that are prone to sticking and leakage and the lower strata with poor drillability, the Bazhou Branch made full use of the advantages of geological engineering integration to carry out drilling speed-up work, constantly challenging the drilling limits and climbing to new speed peaks. The 80005 drilling team selected drill bits and speed-increasing tools based on the conditions of adjacent wells, and repeatedly considered the drill tool combination to ensure that the drilling work was carried out efficiently and smoothly.
According to Zhang Pingduo, Secretary of the Party Branch of the 80005 Drilling Team, the final choice for drilling the full-depth 3-H13 well was a synthetic diamond composite bit + twist punching + high-torque screw to drill the drill plug in one pass; for the upper formation of the second opening is easy to drill Due to its characteristics such as stuck and easy leakage, the drilling parameters were adjusted in a timely manner to continuously optimize the mud performance, ensuring optimal and fast drilling while ensuring smooth wellbore and underground safety. The average machine speed reached 116.5 meters per hour.

Start and run. Since 2023, Bazhou Branch has focused on improving safety, speed and efficiency of single wells. While constantly summarizing experience in speed improvement, it has further modified and improved the block drilling template to promote the continuous increase in drilling speed and block records. "One trip" "Drilling" records continue to be broken, with four wells including Manshen 72-H4, Luchang 5, Manshen 11 and GL3-H4 all exceeding 1,000 meters per day.
"One kilometer per day is the norm, one mile per day is the goal, and we strive to break through 2 miles." Zheng Tanmin, Party Secretary and Executive Director of the Bazhou Branch, said.
