摘要
随着我国致密油气资源的持续开发,水力压裂已经成为各大油田主要的开发手段,而压裂液作为改造储层的主要外来流体,除了起到传递压力和携带支撑剂的作用外,也是储层伤害的主要来源。从评价压裂液伤害对象和不同研究方法适用性的角度出发,综述压裂液对裂缝和基质的伤害机理;研究压裂液伤害的手段:岩心驱替实验、激光粒度仪、扫描电镜法、CT扫描技术、核磁共振技术、三维数字岩心技术,总结各种研究方法的优劣。
With the continuous development of tight oil and gas resources in China,hydraulic fracturing has become the main development means of major oilfields,and fracturing fluid,as the main foreign fluid for transforming reservoirs,in addition to the role of transmitting pressure and carrying proppants,is also the main source of reservoir damage.From the perspective of evaluating the injury objects of fracturing fluid and the applicability of different research methods,the damage mechanism of fracturing fluid to cracks and matrix was reviewed.Methods to study fracturing fluid injury,rore displacement experiment,laser particle size analyzer,scanning electron microscopy,CT scanning technology,nuclear magnetic resonance technology,three-dimensional digital core technology,and summarize the advantages and disadvantages of various research methods.
