Research Of Pu-nan Pilot Area

Pu-nan Fuyu oil layer is a lithostructural reservoir. Its physical property is bad, thickness of sand body is thin, plane of sand body changes soon, expanse of fracturing is high, productivity of individual well is low, and economic effect is bad. Taken goals of the effective production well spacing, fracture and development effect, and taken principle of thickness growing better, testing oil better, the reserves abundance bigger and the development appraisal degree higher as the well block optimal principle, based on the fine structure of the three dimensional seismic data explanation and the result of the reservoir lithologic inversion study, we develops a research of Pu-nan pilot area.Through research in-situ, using 3D seismic data for predicting and optimizing well block of thick sand body for drilling, determining the well pattern deployment method of the Fuyu oil layer which is extraordinary low permeability by using effective driving pressure differential, optimizing well spacing, establishes well pattern of the effective displacement system; Under the effective displacement condition, the rules of producing fluid and water-cut; It is all for the effective development of big area unused reserves of extraordinary low permeability Fuyu oil layer.
