Sinopec News Network News Multi-stage perforation technology is one of the key core technologies in the construction of shale gas staged fracturing and gas testing
Jianghan Logging Branch of Sinopec Jingwei Co.
Bravely break into "no man's land"-break the foreign technology monopoly
In 2012, China opened the prelude to shale gas exploration and development, but its core technology and key equipment are completely blank.
But at that time, there were very few domestic companies engaged in the research and application of this technology
In 2013, the company used its own equipment and technology for the first time in construction, but it failed
"Never admit defeat.
After the first failure, the company upgraded the equipment and applied for admission again, and won the last chance-in Jiaoye 42-2HF well, to compete with the American team on the same stage
Fame in the First World War! The Jiaoye 42-2HF well was successfully completed and set a record for Sinopec’s deepest perforation operation at 5927 meters
In 2015, in only two years, multi-stage perforation was fully localized.
Out of the "comfort circle"-innovation and optimization to enhance core competitiveness
"If there is a secret for our development, the secret lies in technological innovation and fine optimization, and continuous improvement of core competitiveness, in order to win the market and stand firm
From more than 40 million yuan in 2014 to 300 million yuan last year, innovation and optimization time and time again have enabled the production value of multi-level perforation to achieve leap-forward growth
In 2015, although multi-stage perforation was fully localized, there was still a gap in technology.
Everyone thinks about optimization, and optimizes everywhere
In the future, with the continuous development of domestic shale gas, the company will increase its efforts to innovate multi-stage perforating technology and equipment to provide strong support for the efficient and low-cost development of gas fields
