Two innovations in Northwest China have been tested and won national patents

Sinopec News Network reported on June 18 that good news came from the State Intellectual Property Office.

"A kind of expandable open hole packer" is mainly developed in response to the "sparse well and high production" requirement of the Northwest Oilfield, using the open hole packer staged fracturing process to simultaneously mobilize multiple reservoirs to achieve the maximum release of single well productivity.

In order to meet the technological requirements of staged acid fracturing for high-temperature and high-pressure wells and improve the sealing reliability of the open-hole packer during the setting process, the expandable open-hole packer adopts a double-piston structure and a liquid inlet closing mechanism is designed to realize a packer The independent design of the starting setting pressure and the complete setting pressure effectively improves the sealability and reliability of the packer

"A new type of perforation detonator" is a perforation detonation device suitable for oil and gas well tubing transmission.

Reverse circulation can be carried out before perforation.

For a long time, the Well Completion Test Management Center has been problem-oriented, using the "Nine-Thinking" innovation method as a powerful tool to make innovation the first driving force leading the center's high-quality development

As of the day before, the center has obtained a total of 60 patents, of which 52 are valid patents, 50 are utility model patents, and 2 are invention patents
