Shinda’ product assist -- the world's first multi-channel heterogeneous coiled tubing bundle subsurface injection technology has been successfully tested in jilin oilfield

On July 20, the first multi-channel heterogeneous coiled tubing bundle subsurface injection technology of multi-channel heterogeneous continuous tubing bundle in jilin oilfield has been tested in well mu 141-67.1 for nearly a month. This technology is not only the first in China's oil production system, but also unprecedented in the global industry.

It is known that the surface injection technology of heterogeneous coiled tubing bundle string is a new water injection technology initiated by jilin oilfield engineering technology research team after nearly two years of technical breakthrough. It USES four independent channels of heterogeneous coiled tubing bundles to communicate with each oil layer, without any influence. It can realize water injection in four sections through special injection Wells on the ground. Meanwhile, it can remotely monitor and control flow, pressure and other parameters.
