The perforation guarantee of huhwk15 well is the last perforation construction task this year.
As of recently, ccdct has completed the perforation construction of all 6 wells in the gas storage, achieved an overall perforation construction speed increase of more than 154%, and made a positive contribution to the rapid development of the gas storage into a high-quality development path…
In view of the construction difficulty of one-time perforation section of 788m long well section of the well, focusing on the pressure delay perforation technology and the assembly quality of initiating explosive devices in long well section, the branch started to formulate the construction scheme half a month in advance, accurately designed the assembly position of each shot, and carried out multiple calibration and discussion, so as to fully ensure the perforation quality and one-time success rate of perforation.
Hutubi gas storage is the largest natural gas storage in China, which makes an important contribution to ensuring supply in winter.
During construction, the team is equipped with three technical experts to supervise the whole process, and solidly implement the three-level inspection system to ensure efficient and high-quality completion of construction.
Combined with the current ultra-low temperature construction environment of minus 20 ℃, the branch gives full play to the advantages of multi team cooperation to speed up the construction and production cycle of single well.
The three operation teams of CNPC logging Xinjiang Branch successfully completed the tubing transmission perforation construction of well huhwk15 in Hutubi gas storage with a speed-up efficiency of 500%, marking the full end of the perforation construction task of gas storage this year.
