关井后井口压力变化原因的探讨

Discussion on the Pressure Changing of the Well Head after Closed

通过对卤井停产后井口压力的变化分析 ,找出了停井后影响卤井压力变化的三大因素 ,即溶腔的溶解作用、溶腔的卤温上升和溶腔受围岩的压力产生变形作用。分别对这几个因素进行了讨论 。

Three factors have been discovered through analysis on pressure changing of the well head, which are dissolving, temperature and pressure. And it advanced measures for brine well operation.
