摘要
在水力压裂和酸压过程中,裂缝会沿着缝高方向延伸。当裂缝延伸超出产层进入上下隔层时,不仅造成压裂液资源的浪费,而且难以达到设计要求。研究压裂过程中控制裂缝在高度方向上延伸的诸因素,分析了单因素条件下的裂缝高度变化趋势。针对不同因素对裂缝高度的影响,调研了针对这些因素的控缝高压裂技术。
In hydraulic fracturing treatment and acid fracturing treatment, fracture can extend in fracture height orientation. When fracture extends beyond production layer and get into barrier layer, it wastes fracturing fluid resources and it＇s hard to meet design requirement. This paper studies fracture height influence factors during fracturing. By analyzing a case well, tendencies of fracture height has been concluded under single affecting factors. To different influence factors, different gaming techniques have been studied. This paper is worth for some height control fracturing.
