Abstract

In order to predict the erosion life and erosion failure time of the metal mesh, based on the rotating erosion experiments under different working conditions, the erosion mass loss of the metal mesh under different factors was measured by the weight loss method and the erosion mathematical prediction model was put forward. The erosion wear mechanism of the single-layer metal mesh was explored by using electron microscope scanner and optical microscope. The results show that the erosion rate increases exponentially with the increase of liquid velocity (0.5, 1.0, 1.5, 2.0 m/s). When the solid mass fraction (0.3%, 0.5%, 0.8%) and erosion Angle is 15°–45°, the erosion rate is proportional to the solid mass fraction and erosion Angle. After erosion, the mesh samples suffered different degree of pitting corrosion, ploughing and cutting wear, and the mesh wear was local wear. Compared with the experimental value, the error of the erosion mathematical model is less than 20%, which has a certain reliability, and has an important reference significance for guiding the production control of sand oil Wells.

Highlights

Screen pipe is an important downhole tool for sand prevention completion
The failure of sand prevention screen is mainly caused by the erosion wear caused by particles passing through the screen and the increase of erosion wear caused by particles blocking the screen to form a high flow rate erosion area
On the basis of the conditions and influencing factors put forward by the erosion theory at home and abroad, a single variable experiment is carried out on each influencing factor, and a screen life prediction model based on flow rate, solid mass fraction and erosion angle is established by actual production situation of the oil field

Summary

Introduction

Screen pipe is an important downhole tool for sand prevention completion. Screen pipe failure is an important factor leading to sand prevention failure.[1]. Measurement and Control control slotted screen pipes, and established a prediction model for erosion life of slotted screen pipes considering crude oil flow rate, sand particle diameter, sand particle concentration, and erosion angle. Gillespie et al.[23] studied the erosion failure of wire-wound screen and metal mesh screen under open hole completion conditions, conducted several groups of erosion experiments under different velocities and sand concentration, and proposed a screen service life model for given oil and gas well production conditions under open hole completion conditions. On the basis of the conditions and influencing factors put forward by the erosion theory at home and abroad, a single variable experiment is carried out on each influencing factor, and a screen life prediction model based on flow rate, solid mass fraction and erosion angle is established by actual production situation of the oil field.
