【摘要】 压裂是低渗透油藏增产的重要手段和必要手段。压裂后形成的裂缝长度、宽度和高度、渗透率和导流能力是影响压后效果最直接和最重要的因素,通过裂缝监测,可以认识裂缝扩展规律,指导优化压裂设计。通过对目前国内外成熟的几种微地震监测技术的总结,对其技术原理和特点进行了对比阐述,通过微地震监测应用分析,认识了裂缝扩展规律和几种微地震监测技术的特点,对下步微地震监测技术的应用提出了建议。更多还原

【Abstract】 Fracturing plays a key role in low-permeability reservoirs stimulation.The factors which influence the fracturing results directly include the length,width,height,permeability and conductivity of fracture.Through fracture monitoring technologies,expanding law of the fracture is known and could be used to optimize the fracturing design.By summarizing several mature microseismic fracture monitoring technologies,the principles and feature of these are compared and elaborated.Through applications of microseismic technologies,the expansion rule of fracture and unique feature of each microseismic monitoring technology are recognized and the suggestions in the application of microseismic fracture monitoring technology are provided.更多还原
