Hydraulic expandable tubular patching technology for high angle deviated sanding wells in Jidong Oilfield
摘要
Abstract
In view of the difficulties on hydraulic expandable tubular patching technology for high angle deviated sanding wells, the reasons of the expandable tubular patching failure and factors impacting are analyzed, considering the impact of formation property, wellbore status, patching tool, and operating method, on the patching operation for deviated sanding wells. The study results could explain that it is a key technique for deviated sanding wells to squeeze some cement to prevent formation sanding before patching, In order to avoid jamming of expandable tubular patching tools, drill pipe is used to put into the tools. At the same time, the expandable tubular patching technique and tools are improved to resolve the problems of resistance and sealing broken of high angle deviated well. The technique is successfully applied on Well G308-4, with deviation angle of 30 degree and serious sanding problem.关键词
