COMPREHENSIVE CHARACTERIZING TECHNIQUE OF THE RESERVOIR FRACTURES IN DAQING PERIPHERAL OILFIELDS
摘要
Abstract
Daqing peripheral oilfields are mainly characterized by low-permeability & ultra-low-permeability reservoirs and well-developed natural fractures. In the light of the issue of serious influences of the reservoir fractures on the performances of oilfield water flooding, with the help of the analyses and studies on the monitored data of the fractures, the method researches on the fracture characterization, forecast and comprehensive describing method are deeply carried out, and moreover the dual- porosity media fracture modeling approach is studied, thus a set of complete quantified characterizing method of low-porosity and low-permeability reservoir fractures is established, the fracture network model and dual-porosity media model are built, so the geometric model of the fractures can be converted into equivalent media model, finally the technical problems of the geological modeling for the reservoir fractures is generally solved. The study achievements have extensively applied in the oilfield development and the much better social and economical effects have been acquired. In a word, the achievements have possessed important guiding significance for the fine development adjustment of heterogeneous fractured oilfields. characterization of reservoir fracture; fracture forecast; seismic ant-tracking; fracture modeling, dual-porosity media关键词
