Resin-rubber composite special-shaped body

Abstract

The invention relates to the technical field of petroleum drilling leakage stoppage, in particular to a resin-rubber composite special-shaped body. With high-temperature-resistant and high-strength resin and alloy are adopted as raw materials, triangular pyramid, cone and rhombuses bridging particles with taper angles and different sizes are prepared through high-temperature mixing and squeezing. The bridging particles have obvious taper angles, are easy to enter a stratum crack, are not easy to flow back, have extremely high temperature resistance and pressure resistance, and can be used as a primary bridging material with excellent performance, so that the leakage stoppage success rate of a malignant leakage well is increased. The resin-rubber composite special-shaped body is prepared from the following raw materials: a resin molding agent, a resin solidification accelerator, a strength enhancer, a density regulator and a compatibilizer.

Description

technical field [0001] The invention relates to the technical field of oil drilling plugging, in particular to a resin-rubber composite irregular body. Background technique [0002] Resin-rubber composite profile is an auxiliary device for oil drilling plugging, which has been widely used in the field of oil drilling plugging; the existing resin-rubber composite profile is found in use, and the bridging plugging agent currently used is mainly Derived from agricultural and sideline product leftovers and natural minerals, the main bridging particles have the disadvantages of insufficient temperature and pressure resistance, especially in high-pressure wells, ultra-deep wells and wells with leakage in the same layer. Due to the technical shortcomings of plugging materials and to improve the success rate of bridging plugging, major scientific research institutes and specialized companies are devoting themselves to the research and development of high-strength, high-temperature-r...
