【摘要】 姚店油田注水试验区王84井组微量物质示踪剂动态监测结果分析表明,井间微裂缝和高渗条带是控制注入水快速突破的主要因素。在注水初期,微裂缝和高渗条带起主要驱油作用,注入水突破是导致含水率快速上升的主要原因。分析认为采用分层注水或周期性注水,可以进一步提高注水波及体积,提高驱油效果。更多还原

【Abstract】 Micro-fractures and high permeability channel are the main factor controlling injected water move quickly in accordance with the behavior well test of Wang 84 well group in water injection experimental region in Yaodian oilfield. Micro-fractures and high permeability channel are the major power of driving oil during the initial stage and the leading reason caused water -bearing quickly rise while the breakthrough of injection water. On the basis of this method, delaminating injection or injecting water periodically are suggested to carrv out in order to improved further the development efficiency.更多还原
