摘要:
评价压裂裂缝空间分布的方法较多,其中近井监测以偶极声波测井为主,监测精度高,但其横向监测范围仅为井筒附近;远井监测以井中微地震实时监测技术为主,该方法可对裂缝多尺度评价,但受模型及本身监测方法的影响,其监测精度大约在10 m以内。为有效评价压裂裂缝空间展布特征,以长庆油田某区块低渗透油藏注水开发X90-5压裂井为例,通过井中微地震监测技术对压后裂缝进行总体空间展布分析,结合偶极声波近井地带地层各向异性分析技术和井组注采关系分析对储层压裂效果进行综合评价,2种方法相互印证、相互弥补,对储层压裂改造信息进行了全面描述,使结果更加全面、合理,弥补了单项方法的局限性。
Abstract:
There are many methods to evaluate fracture space distribution at present. Dipole acoustic log data monitors the fractures near a wellbore. Its monitoring accuracy is high, but the lateral monitoring range is just near the wellbore. Micro-seismic survey monitors the fractures far from a wellbore at real time. This method can evaluate different sizes of fractures, but affected by the model and the monitoring method, its accuracy is within about 10 m. Taking the fractured well X90-5 in a low-permeability block developed by waterflooding in Changqing oilfield as a case, the two methods were combined to analyze the fracture distribution in the well. First micro-seismic data were used to describe the overall fracture distribution, then near-wellbore dipole acoustic anisotropic data were used to further analyze the result by considering the injection-production pattern. The two methods confirm and complement each other. Their combination provides complete description of fractured reservoirs. The result is more reasonable and reliable than that of a method.
