Zhuang9Well Area Of Xifeng Oilfield Flood Development Well Pattern Adaptability Research

Low permeability reserves rich, natural physical property is poor, diiffcult exploitation,exploitation degree is low. Reasonable well pattern and well network parameters and fractureparameters configuration can effectively improve the low permeability reservoir developmenteffect, therefore, study well pattern adaptability, selection of well pattern and well networkparameters reasonably, become a key problem in low permeability reservoir is one of theeffective and economic development.Use the Xifeng Oilifeld He Shui areas Zhuang9well area of research and developmentwell block as the research objcct and study applications laboratory expeirmental data andlogging，logging a better understanding of the structural features of the Zhuang9well area,reservoir characteristics, fluid characteirstics, reservoir typesand and the original drivepressure type; based on understanding of the regional geology and fluid characteristics，in thecourse of development of the well area as a reference to the oilifeld developmentcharactcristicsthc development characteirstics of fractured reservoirs> and reservoir walerflooddevelopment effects to be evaluated; to more than two partsthe content is based oridevelopment scheme and wall pattern arrangement for Zhuang9well well networktransformation before and after different forms of well network, well spacing density，andwellhead spacing rationality.
