摘要
介绍了国内外近年来地应力及射孔参数对水力压裂影响方面的理论和实验研究进展,主要包括任意方位和井斜角下井眼壁面地应力分布、地应力与裂缝走向的关系、射孔方位及间距对裂缝起裂及发展的影响、其他参数(压裂液粘度、排量等)对压裂效果的影响等研究成果,指出了目前研究中存在的不足,并对未来研究方向进行了分析与展望。
The theory and experiment research advance of the influence of geostress and perforation parameters on hydraulic fracturing was introduced, The researched results were mainly summarized on the aspects of geostress distribution of wellbore wall with arbitrary bearing and angle of deviation, the relationship between geostress and fracture propagating direction, the influence of perforation orientation and interval on fracture initiation and propagation, the influence of other parameters, such as fracture liquid viscosity and flow rate, on the fracturing effectiveness. Based on the summarization, the questions of the present study and the further research orientation were pointed out.
