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。分析裂缝发育与地应力的关系,并考虑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。 Using microseismic fracture monitoring technology, fracturing and fracture monitoring of Block A in an oilfield was conducted. Seismogenic sources were determined by receiving microseismic signals at the time of formation rupture and microseismic source localization. Understand the spatial distribution of the source, so as to determine the shape, orientation and height of the crack. The relationship between fracture development and geo-stress is analyzed. Considering the combined effect of natural fractures and artificial fractures under geostress, it is ready for the next step to optimize fracturing design and well pattern optimization so as to provide a basis for efficient development of low permeability reservoirs .
