OIL-GAS RESOURCES EXPLORATION AND PRODUCTION CAPACITY STUDY OF FUXIN BASIN

Based on the geological conditions and oil-gas exploration results of Fuxin Basin, the LFD-2 well is tested to determine the geological, resources and occurrence conditions of oil-gas resources in the basin. According to the measured critical analytical pressure of each reservoir, the ground stress gradient of the area is about 0.013 kPa/m, with the reservoir fracture pressure of 10.6-11.5 MPa. The oil-gas productivity test shows that the highest daily oil output is 16.86 t and daily gas output 2 584 m³ in LFD-2 well. The coalbed methane (CBM) reserves in the basin of LFD-2 well is evaluated as a small-scaled gas field with medium productivity, which provides a basis for the following geological exploration and mining work.
