Research of characteristics of oil and gas transportation systems in LiuChu area

摘要

Based on a variety of factors, such as the certainty of oil-migrating faults and their sections of ridges, the matched pattern of fractures and sand body conductive systems, and superface structural forms of sand body conductive systems, in this paper we applied seismic inversion technique, moreover, we determine dominant horizons of oil and gas lateral distribution and the direction of oil and gas further migration. Thereby we established the pathway system of hydrocarbon source rock fracture and sand body trap, also used formation testing of agent review well, logging and electric logging interpretation data to verify the migration path of oil and gas. It turned out that the fault is the only path for of vertical migration of oil and gas, and the section of the ridge is the dominant path of oil and gas vertical migration. Oil and gas chose sand layer with good physical character to fill first, after that, it occurred lateral migration along the conducting ridge composed of structural ridge and high permeability sand body.
