Recently, the Jianghan Oil Production Plant of Jianghan Oilfield has perforated the new well Guang 3 Oblique-25 Well, which has a daily output of 4.
2 tons of high-yield oil flow
.
The upper section of Guanghua in Jianghan Oilfield was put into development in 1970 and has been developed for more than 50 years.
The degree of recovery of geological reserves has reached 61.
49%, and the main layer is seriously flooded
.
This year, the geotechnical staff of the plant carefully explored the thin and poor layers or regions, carried out the study of the remaining oil distribution law, combined with the longitudinal physical property differences, analyzed that the production wells in the high part of the Qian 31 oil group in the Qian 311.
In the next step, the geological technicians of the plant will continue to strengthen the understanding of the remaining oil potential of the thin and poor layers, optimize the potential layer series, implement adjustments and improvements, and help stabilize production and increase efficiency in old areas
