Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a preparation method of a new basalt composite material bridge plug, which has the advantages of high temperature resistance stability and high mechanical strength, and solves the problem of bridge plugs with higher technical requirements as the market demands. Putting it on the agenda, such as temperature resistance of 150°C, pressure difference of 70MPa, pressure duration of 8-24H, and composite slips instead of metal slips, etc., but the bridge plug can only withstand high temperature of 120°C and pressure of 40Mpa, which obviously does not meet these needs question

Abstract

Relating to the technical field of bridge plug preparation, the invention discloses a preparation method of a novel basalt composite bridge plug. The method includes the steps of: 1) crushing 100-300parts of basalt raw material to obtain basalt particles, crushing 200-600 parts of sepiolite raw material to obtain sepiolite particles, and mixing the obtained basalt particles with sepiolite particles to obtain mixed particles. The preparation method of the novel basalt composite bridge plug carries out crushing and mixing on basalt particles and sepiolite particles, and performs high-temperature melting to obtain the composite material. Basalt has good heat resistance and crack resistance, and sepiolite has good heat dissipation performance and acid-alkali resistance, thus greatly improvingthe heat dissipation performance and chemical stability of basalt, also further improving the flexibility of basalt, and making basalt not easy to become brittle. Therefore, the composite material formed by the two achieves the purposes of high temperature stability and high mechanical strength.

Description

technical field [0001] The invention relates to the technical field of bridge plug preparation, in particular to a preparation method of a novel basalt composite material bridge plug. Background technique [0002] The role of the bridge plug is to seal the oil and gas well, which has the characteristics of less construction procedures, short cycle and accurate sealing position. It is divided into two types: permanent bridge plug and removable bridge plug. With the maturity of hydraulic fracturing technology and the occurrence of trade wars, it is imperative to replace imported bridge plugs with domestic composite bridge plugs. [0003] There are various methods for preparing bridge plugs. For example, Chinese patent CN 103725274 B discloses a chemically formed fluid bridge plug resistant to high pressure and controlled degradation and its preparation method and application. The fluid bridge plug is made of acrylic acid at room temperature Add sodium, acrylamide, dimethyl di...
