Simulated Oil Downhole Tools Erosion Failure Experiment Device Design Research

Abstract

Hydraulic fracturing technology in low permeability, shale gas and unconventional oil and gas reservoir plays an important role in the process of transformation, with the more difficult exploitation of oil and gas, the fracturing sand content and displacement is also increasing, downhole tool erosion failure is more and more frequent, so we developed a casing streaming liquid-solid two phase flow erosion experiment platform, the platform can be a real simulation of the field production conditions, in order to obtain the real tool failure reasons of erosion, the obtained conclusion by analyzing the reasons, applies in the middle of the actual, make oil downhole tools to control and prevent erosion failure phenomenon.
