PEEK Polymer Nonmetallic Materials Replace Research in Drillable Metal Bridge Plug

Abstract

The bridge plug as a downhole plugging tool, bridge plug is mainly used in oil recovery position, fracturing , water plugging, testing, temporarily seal technology measures ect, have simple construction and high pressure difference, long seal time and accurate position etc., become an effective technology in reservoir reconstruction, which has been widely used in underground work process. After decades research and application, foreign bridge plug in the high temperature resistance, high pressure resistance, multi-purpose, new materials, recycling and reliability etc have made considerable progress. In recent years, domestic also initially formed series bridge plugging technology, and in constant development and improvement, but the present commonly used metal bridge plug mill deblocking exist great difficulties, especially in large slope, horizontal milling deblocking more difficulty and complex than vertical well , in order to solve this problem, develop nonmetallic material bridge plug.
