| 摘 要： | 桥塞分段压裂是页岩气水平井开发的主导技术之一,但受储层特性以及施工决策等因素的影响,超压砂堵很难避免。分析解堵机理,依据井筒中有无高粘度液体以及顶替是否完成将砂堵分为8种类型;结合页岩气储层地质、工艺特点,提出了采用疏通老缝和压开新缝的解堵方法。

| Abstract: | Controlled by formation properties and operation decision, it is difficult to avoid overpressure sand plug in the process of bridge--plug staged fracturing, one of leading technologies used in the development of shale gas horizontal wells. Sand plug is divided into eight forms according to plug removal mechanism, high viscosity liquid in the borehole and displacement completion. Combined with the characteristics of shale gas reservoir geology and process, this paper introduces a method for plug removal through tmchoking old fractures and opening new fractures by pressure. |
