【摘要】 利用微震裂缝监测技术,对某油田的A区块进行压裂裂缝监测。通过接收地层破裂时的微震信号和微震震源定位方法确定震源。了解震源的空间分布,从而确定裂缝的形态、方位、高度及产状。分析裂缝发育与地应力的关系,并考虑现今地应力状态下天然裂缝和人工裂缝的综合影响,为下一步的优化压裂设计、优化井网做好准备,从而为低渗透油藏高效开发提供依据。更多还原

【Abstract】 Micro-seismic monitoring technology is used in A block of some oil field to monitor fractured cracks.By accepting breakdown signal of the micro fracturing,we used the microseismic source orientation method to determine the seismic source,then we figured out the fracture morphology,orientation,height and attitude with knowing the spatial distribution of the source.Furthermore,through the analysis of the genenral effect of stress and fractures,with the consideration of current state of natural fracture stress and the combined effects of artificial fracture,it will benefit the further optimization fracturing design and well network,thus we were offered a basis for low permeability reservoirs’ efficient development.更多还原
