Technological innovation in Northwest Oilfield to achieve high oil and gas production in ultra-deep formations

Recently, the Petroleum Engineering Technology Research Institute of Northwest Oilfield Branch adopted the small-span controlled fracture and high-acid pressure technology in the TK4119X well to achieve high yield.

Well TK4119X is a development well located in the Shunbei Oilfield of the Tarim Basin.

The technology of small-span reservoirs with controlled fracture and high acid fracturing was independently developed by the Northwest Oilfield Petroleum Engineering Technology Research Institute, and has obtained a national invention patent, which is suitable for water-controlled oil production in carbonate reservoirs.

In order to put the well into production as soon as possible and extract oil and gas from the deep strata, the reservoir reconstruction technicians after comparison and optimization, boldly adopted this independent innovation technology to open a high-speed passage between the wellbore and the oil and gas fractured caves.
