Research and Application of a Liquid Bridge Plug as Wellbore Working Fluids

Abstract:

The research and application of LH-I liquid bridge plug - a kind of wellbore working fluid for plugging the lower formations are introduced in detail in the paper. The plug is reliable and easy to operate, eliminating the running and pulling of strings in mechanical plugging and requiring no fishing operations. It can be used for isolating and plugging the lower formations inside the wellbore, especially for wells with small barrier layers, hard to set wells, initial sand control wells, and wells completed with 177.8mm (7〞) casing and 127mm (5〞) tail pipe, in which mechanical packers and mechanical bridge plugs can not be used.
