"Zipper-style" fracturing construction was used in Hangjinqi block to set a new record

China Petrochemical News Network reported on April 9th ​​that the Second Gas Production Plant of North China Oil and Gas Branch first tried to use the “zipper-type” factory fracturing operation in the JPH-480 well group in the Hangjinqi block and succeeded, creating the company's horizontal wells.

The JPH-480 well group has two wells, JPH-480 and JPH-481, which are two development horizontal wells deployed by the North China Oil and Gas Branch in the Hangjinqi block of Ordos City.

Since the beginning of this year, in order to improve the construction efficiency and save costs, the No.

According to the construction design, the well group is fully reformed with the mixed water volume fracturing process of "dense cutting segmentation, multi-cluster perforation, large displacement + complex fracture network".

At the same time, it is emphasized that after the blowout prevention pipe is installed and the bridge plug is inserted into the well to start pumping, the fracturing operation of another well can be started to ensure the safety of construction personnel and ensure the timely supply of fracturing fluid.

During the construction, the Petroleum Engineering Department of the Second Gas Production Plant, the Engineering Institute and the Supervision Center’s management personnel maintained close communication with the North China downhole personnel during the construction, and kept a close eye on various parameters on site, strictly supervised the important links, and with the efforts of many parties, the final time was spent A total of 14 fracturing operations in two wells of the well group were successfully completed within 72 hours.
