Problems solved by technology

[0003] The purpose of the present invention is to provide a metal screw pump vertical simulation experiment method, which overcomes the fact that when the existing horizontal test bench is running, the rotor is concentrated on the stator part near the ground due to its own weight, especially in high-speed, sand-containing In the running state, it will increase the wear of the stator, and it cannot simulate the working state of the screw pump well in the well.

Embodiment Construction

[0017] The detailed description and technical content of the present invention are described below with the accompanying drawings, but the accompanying drawings are only provided for reference and description, and are not intended to limit the present invention.

[0018] like figure 1 As shown, a metal screw pump vertical simulation experiment method includes a drive system, a pump system, and a stirring system connected in sequence. The drive system and the pump system are both vertically arranged, and the pump system is vertically arranged on a support , while the drive system is vertically connected to the power input end of the pump system; the pump system and the mixing system are connected in a circular manner through the pump-in pipeline and the pump-out pipeline, and the pump-in pipeline between the pump system and the mixing system A metering system is connected to it. The driving system drives the pump system to work. The pump system sucks the sand-containing liquid...

Abstract

The invention discloses a vertical simulation experiment method of a metal screw pump. The drive system drives the pump system to work, and the pump system sucks the sand-containing liquid in the stirring system into the pump body through the pumping pipeline, and pumps it into the pipeline for metering at the same time. The system completes the metering work, and then the pump system pumps the sandy liquid back into the mixing system through the pumping pipeline; due to the vertical setting of the drive system and the pump system, the fit clearance of the stator and rotor in the pump system will not be affected by gravity , and then well simulate the working state of the pump system in the well, and realize the accurate simulation of different media movement conditions in the vertical flow direction. The present invention has the following remarkable advantages: 1. Vertical experimental device structure: the vertical installation of the stator and rotor is realized, which avoids the influence of gravity on the fit gap of the stator and rotor; 2. Different media (sand, gas, moisture content ) accurate simulation of motion conditions.

Description

technical field [0001] The invention relates to a simulation experiment method of an oil field screw pump, in particular to a vertical simulation experiment method of a metal screw pump. Background technique [0002] Affected by its own weight, the stress of the screw pump rotor is concentrated on the stator part near the ground, especially in high-speed, sandy operating conditions, which will increase the wear of the rotor on the stator. In order to better simulate the working state of the screw pump in the well, more To accurately grasp the wear resistance characteristics of screw pumps under the condition of adding sand, it is necessary to design a new vertical simulation experiment method for metal screw pumps. Contents of the invention [0003] The purpose of the present invention is to provide a metal screw pump vertical simulation experiment method, which overcomes the fact that when the existing horizontal test bench is running, the rotor is concentrated on the sta...
