Abstract

The erosion mechanism of L80 steel under alternating injection-production conditions was studied by experiment and numerical simulation. A self-designed jet gas–liquid-solid erosion test system was used to simulate multiphase flow environment. According to the experimental and numerical simulation results, when the impact Angle is 0–30°, the erosion rate increases with the increase of the Angle, and when the impact Angle is 30–90°, the erosion rate decreases with the increase of the Angle. The erosion mechanism of gas storage pipe column mainly includes micro-cutting, furrow and impact deformation. Sand accumulation, embedded particle fragmentation and cutting “lip” in the gas production stage will be carried by high-speed gas and fall off during the gas injection stage, causing secondary erosion to the string. In this study, the erosion characteristics of L80 steel under different impact angles under alternating injection-production conditions were revealed, and the impact Angle function was established.

期刊介绍： Chemical engineering enables the transformation of natural resources and energy into useful products for society. It draws on and applies natural sciences, mathematics and economics, and has developed fundamental engineering science that underpins the discipline. Chemical Engineering Science (CES) has been publishing papers on the fundamentals of chemical engineering since 1951. CES is the platform where the most significant advances in the discipline have ever since been published. Chemical Engineering Science has accompanied and sustained chemical engineering through its development into the vibrant and broad scientific discipline it is today.
