The Numerical Simulation of Serious Flooded Area of Jin-45 Block

DUAN Xiaowei

Abstract


The serious flooded area of Jin-45 Block began trial mining in 1984, Expericing conventional dry pumping, steam stimulation test and large-scale steam stimulation[1-2]. After nearly 30 years’ development with active edge and bottom water and sufficient energy, there is a high percentage of reserves and the plane and vertical plane encryption, can’t be adjusted. The condition of edge and bottom water is serious, average recovery rate of water of producing wells is high, production decline amplitude increase, exposing a series of problems. Referring to the steam stimulation turn to steam drive experience of pilot test area, building geologic model with Petrel software, setting up edge and bottom water reasonably, making history matching and project estimate, analyzing characteristics of steam flooding of the flooded area. Providing theoretical guidance and basis of turning to steam flooding of serious flooded area[4-6].
