低渗砂岩油藏压驱增产关键指标协同优化方法
Synergistic optimization method for key production enhancement parameters in pressure drive of low-permeability sandstone reservoirs
摘要
Abstract
Low-permeability sandstone reservoirs exhibit poor reservoir properties and weak flow capacity,making pressure drive technology a core approach for efficient development.However,the synergistic optimization decision-making method for key indicators throughout the full life cycle management of pressure drive production enhancement—specifically"fracturing-permeability enhancement-soaking-displacement"(fracture-enhance-soak-drive)—remains unclear.By constructing a multi-mechanism refined numerical model that considers reservoir energy replenishment,pore expansion and permeability enhancement,pressure-driven fracturing,and shut-in imbibition effects,this study systematically investigates the synergistic optimization of pressure drive well patterns,development modes,and production schemes.Results indicate that the inverted seven-spot well pattern and reverse pressure drive respectively outperform the seven-spot well pattern and forward pressure drive.The influence weights of injection volume and injection timing on development effectiveness exceed those of injection rate and shut-in duration;injection volume should be controlled until the formation pressure coefficient no longer increases significantly.The optimized methodology was applied to the pressure drive scheme design for Well Group Y in Block Lu 46 of Huabei Oilfield,yielding significant daily oil production increases after field implementation.The established synergistic optimization method for key indicators of"well pattern configuration-pressure drive mode-injection parameters"provides scientific basis and engineering practice reference for pressure drive production enhancement design in similar low-permeability sandstone reservoirs.关键词
