Determination system of erosion rate and method thereof

Abstract

The invention provides a determination system of an erosion rate and a method thereof. The system comprises a first gas source, a first compression pump, a heating device, a high pressure loop, and several ultrasonic probes, the several ultrasonic probes are distributed at a preset position outside a tube wall of a bend sample, and the first gas source is used for introducing first gas in the high-pressure loop according to a first flow velocity; the first compression pump is used for providing the preset pressure intensity for the high-pressure loop; the heating device is used for heating thegas through a guide pipe to preset temperature; and the several ultrasonic probes are used for obtaining the erosion rate of the bend sample. The high-temperature high-pressure work environment of the bend can be simulated by using the first gas source, the first compression pump, the heating device, and the high-temperature high-pressure loop, the erosion rates at the different positions can realize real-time acquisition by the several ultrasonic probes arranged at the preset position of the bend sample, and the technical problems of the erosion rates at the different positions of the tube wall of a bend pipe can be accurately determined in a real-time mode which is existed in the prior art.

Description

technical field [0001] The present application relates to the technical field of oil and gas exploitation, in particular to a system and method for determining erosion rate. Background technique [0002] In the process of oil and gas extraction, the high-speed moving fluid often causes erosion to oil pipes, wellheads, and surface pipelines, that is, damages the pipe walls of oil pipes and wellheads, such as corrosion or wear on the pipe walls. When the above-mentioned fluid also contains solid phase particles such as sand grains, the above-mentioned erosion effect will be more serious, and even perforations will be formed on the pipe wall of the tubing and wellhead, affecting the normal production of oil and gas. Therefore, during specific construction, the erosion rate of the tubing and wellhead walls is often analyzed first, so that subsequent measures can be taken to protect the tubing and wellhead walls in order to reduce erosion. damage and prolong service life.
