China Petrochemical News Network News Up to now, of the 25 oil wells implemented in the polymer zone in the Wang 17 well block of the Wangji Oilfield in Henan Oilfield, 20 have been effective, with an efficiency of 80%
.

The daily oil production in the well area is 63 tons, and the comprehensive water cut is as high as 86.

Henan Oilfield Wang 17 well area was put into development in February 1987, with an oil reservoir area of 2.
32 square kilometers and a geological reserve of 1.
83 million tons
.

Oil wells have entered a period of high water-cut development.

During the polymer injection process, the geotechnicians of Henan Oilfield strengthened the monitoring of polymer injection concentration, injection volume, polymer injection pressure and other parameters in polymer injection wells, analyzed the direction of underground polymer channeling in the oil well, and controlled polymer channeling to ensure the polymer flooding effect.

.

According to the technical staff of Henan Oilfield Research Institute, they will implement polymer flooding in the well area for 5 years as planned
.
