Crude oil pipeline ball passing and wax removal simulation experiment device and experiment method

Abstract

The invention relates to a crude oil pipeline ball passing and wax removal simulation experiment device which comprises an operation desk, wherein a test pipeline is fixed on the operation desk; a ball serving barrel is coaxially arranged at the rear end of the test pipeline; a pipeline cleaner is coaxially arranged in the ball serving barrel; an acrylic cover body is arranged on the operation desk; a hanger rail is fixedly arranged on the inner side of the top of the acrylic cover body; a guide pulley block is slidingly arranged on the hanger rail; a sensor hanging bracket capable of adjusting tension is fixedly arranged under the guide pulley block; a tension sensor is horizontally arranged on the sensor hanging bracket; the front end of the pipeline cleaner is connected with the tension sensor via a first hauling rope; the front end of the tension sensor is connected with a hauling driving system via a second hauling rope; the tension sensor is electrically connected with a measurement and data acquisition system; and the hauling driving system is electrically connected with a servo control system. The device can measure the strength of a wax deposit on a wall of a crude oil pipeline and change of wax removal resistance in a pigging process.

Description

Technical field [0001] The invention relates to an experimental simulation device, in particular to a crude oil pipeline through-ball wax removal simulation experimental device and an experimental method. Background technique [0002] The terms involved in this case are explained as follows: [0003] Pipe cleaning: In order to reduce the frictional resistance of oil and gas pipelines, it is necessary to promptly remove wax, condensate layer, mud, sand, rust and other debris deposited on the inner wall of the pipeline, or condensate and hydrate remaining in the pipeline, which is called cleaning in the petroleum industry. tube. The method of pipe cleaning is to put a pig (ball) in close contact with the inner wall of the pipe in the pipe, and move along the pipe wall under the pressure of the oil (gas) flow, and then scrape the deposits on the pipe wall or push it out. Fluid accumulation in the tube. Generally, the pump station and hot station (or compressor station) of the oil (...

Problems solved by technology

[0011] From the above background research, it can be seen that most of the technical content of the existing published patents is concentrated on the design of new pipe pigs and the development of new tools and new processes on site. At present, it has not been involved in the strength of wax deposits or the pipe wall during pigging. Indoor Simulation of Wax Deposit Exfoliation
