Device applied to material object erosion-corrosion test of engineering pipe

Abstract

The invention discloses a device applied to the material object erosion-corrosion test of an engineering pipe. The device comprises an engineering experimental pipeline, a gas circulating module, a liquid circulating module, a heat dissipation module, a heating module and an automatic control and data acquisition module, wherein the engineering experimental pipeline is used for fixing the engineering pipe to carry out the material object erosion-corrosion experiment; the medium outlet end of the engineering pipe is connected with one end of each of the gas circulating module and the liquid circulating module by virtue of the heat dissipation module; the medium inlet end of the engineering pipe is connected with the other end of each of the gas circulating module and the liquid circulating module by virtue of the heating module. The device applied to the material object erosion-corrosion test of the engineering pipe can be applied to simulation of high-temperature, high-pressure and multi-phase flow medium conditions in the underground of oil and gas fields and can be also applied to study on corrosion resistance and corrosion law of metal pipes under the high-temperature, high-pressure, multi-phase flow and corrosive medium conditions.

Description

technical field [0001] The invention relates to the technical field of oil and gas field development, in particular to an engineering pipe erosion corrosion test device. Background technique [0002] Corrosion problems in the petroleum industry exist in all aspects, especially the high temperature, high pressure and CO 2 、H 2 The erosion and corrosion problem of oil casing under the action of S air flow is more serious, and the damage is huge. Domestic oilfields, especially several major oilfields in the west, generally have serious corrosion problems of oil casings caused by high temperature, high pressure, and scour air flow, and have not been well solved. One of the main reasons is the lack of necessary research methods, which leads to the There is a lack of necessary and clear understanding of the corrosion mechanism and laws of oil and casing in such an environment, and there is a lack of scientific basis for the selection of oil and casing materials and protective me...
