Oil exploitation and sand removal all-in-one machine and sand removal method thereof

Abstract

The invention relates to the technical field of energy exploitation, and discloses an oil exploitation and sand removal all-in-one machine and a sand removal method thereof. Fan blades in a turbine are close to the outer side, so that the flow speed of the outer side is larger than that of the center when oil generates vortexes; according to the Bernoulli principle, sand in the oil moves to the outer side; as the oil continuously enters the inner part of an oil cavity to enable the liquid level of the oil to continuously rise, the position, close to the center, of the liquid level of the oil in the oil cavity finally makes contact with the bottom of an oil outlet pipe; due to the fact that gravel in the center flows to the outer side at the moment, no gravel exists in the oil close to the center any more, then no gravel exists in the oil entering into the oil outlet pipe, and then filtering operation on the gravel in the oil is finished. Compared with a traditional device for filtering the gravel through a filtering element, the oil exploitation and sand removal all-in-one machine has the advantages that the problem that the flow speed is decreased due to the fact that a surface filtering screen is continuously blocked by the gravel while the gravel is filtered through the filtering element is well solved, and the flowing stability of the oil in the filtering process of the machine is improved.

Description

technical field [0001] The invention relates to the technical field of energy exploitation, in particular to an oil exploitation sand removal integrated machine and a sand removal method thereof. Background technique [0002] Petroleum is the blood of machinery and the most important source of energy in the world today. Various fuels such as gasoline, diesel, kerosene, asphalt and other industrial products need to be extracted from petroleum. Since petroleum is generally stored in underground oil layers, the process of mining It will cause a certain amount of sand and gravel in the oil, which will reduce the quality of the oil, and will also cause wear on the inner wall of the transportation pipeline. For sand operations, traditional sand removal devices only use filtration, which is relatively simple and convenient to do, and is currently the most widely applicable sand removal method. [0003] Although it is convenient to filter and remove sand, it needs to constantly rep...

Problems solved by technology

[0004] Aiming at the shortcomings in the use of the existing integrated sand removal machine for oil exploitation proposed in the background technology, the present invention provides an integrated sand removal machine for oil exploitation, which has the advantage of not hindering the flow of oil in the pipeline, and solves the problem of traditional filter element filtration. The problem of sand causing the flow rate of oil in the pipeline to drop
