人工裂缝监测技术研究

摘要
水力压裂是开发低渗透油气藏的主要增产措施。压裂后形成的裂缝是低渗油藏油气的重要流通通道,裂缝参数是探究压裂成败及增产效果的重要因素。由于在地层产生的人工裂缝无法直观的观察,施工的成败就无法直接检验,因此对人工裂缝的监测就尤为必要。裂缝监测的方法主要可分为:直接的远场裂缝监测枝术、直接的近井筒监测枝术、间接监测方法。通过对各裂缝监测技术的原理、应用以及优缺点综合全面的调研以及对各种技术的对比,得出每种监测技术的适用条件,对现场实施裂缝监测具有一定的指导意义。
Hydraulic fracturing is the main stimulation measures of low permeability reservoir and a main method for enhancing oil/ gas recovery.Fractures are the main seepage channel after hydraulic fracturing,however,fractures in the formation are unable to be observed intuitively,the fracturing effects can not be evaluated directly.Therefore fracture monitoring study is even more necessary. The Fracture monitoring technique is mainly classified into: direct far field fracture monitoring,direct near well bore fracture monitoring and indirect fracture monitoring.Through the comprehensive study of the principle,application and advantages and disadvantages of the fracture monitoring,the contrast of all kinds of technologies,the applied conditions of each monitoring technology are summarized,which will help to choose a more reasonable fracture monitoring technology.
