Bohai Drilling Northwest Market Carefully organized drilling speed up and good results

A few days ago, the full-depth 807 well drilled by the 90023 drilling team in the northwest market of Bohai Drilling Third Drilling Company successfully completed the first opening operation, and the drilling speed was increased by 32.64% by releasing the "three highs and two large" parameters, and good results were achieved.

During the construction, the well further strengthened the large displacement and the pressure drop of the drill bit nozzle, improved the water injection efficiency of the drill bit, optimized the drilling parameters, and achieved rapid drilling and efficient rock breaking. Compared with the same period of the ManS7-H16 well, the drilling period was shortened to 2.42 days, and the overall speed was increased by 32.64%.

At the same time, the team implemented the winter construction requirements, strengthened the post insulation inspection, strictly implemented the anti-freezing and plugging measures, and carefully organized production materials and drilling tools to achieve seamless connection. The cadres on duty take advantage of the production gap, combined with the working conditions, to carry out the "four stresses, two checks and one examination" practical practice on the spot, pay attention to the fine operation and standardized operation of the post, and do a good job in the maintenance of ground equipment in advance to avoid affecting production due to ground equipment.

Strengthen the control of the production process, carry out technical disclosure before drilling, all employees understand and master the construction measures and stage goals, adhere to the daily technical meeting, and experts prompt the risk of the well in real time, and make suggestions for the next step. The regional speed-up template was used, combined with the actual well, the comparison of the wells was strengthened, and the drilling parameters were adjusted and optimized in time to ensure that the operation process was stable and controlled, and the construction of the well was completed with high quality.
