Abstract

The invention relates to the technical field of atomizing devices, in particular to an atomizing generator and a special high-pressure atomizing generating device used for oil-gas field production increase. The atomizing generator comprises a medicine tank assembly, a gear pump, a metering pump, an atomizing generator body and pipelines, wherein the gear pump is connected to the medicine tank assembly through the medicine tank liquid inlet tube; the metering pump is arranged between the medicine tank assembly and the atomizing generator; the medicine tank assembly is connected to a high-pressure liquid inlet pipeline through a low-pressure manifold pipeline; the high-pressure liquid inlet pipeline is connected to the liquid inlet tube; the liquid inlet tube is connected to the metering pump; a gas inlet tube is connected to a high-pressure gas source through a high-pressure gas inlet pipeline; the gas inlet tube is arranged on a gas inlet sealing head; a discharge tube is arranged on adischarge sealing head; a rotatable stirring block is arranged inside a barrel body of the atomizing generator; and the discharge tube is connected to a high-pressure atomizing discharge pipeline. The atomizing generator can disperse chemical additives into high-pressure nitrogen gas on ground, and uniform and stable mist fluid is injected into a ground layer, so that the chemical additives are in sufficient contact with media such as crude oil in the ground layer, and therefore, swept volume is expanded, and using effect of the chemical additives is sufficiently brought into play.

Description

technical field [0001] The invention relates to the technical field of atomization devices, in particular to an atomization generator and a special high-pressure atomization generation device for oil and gas fields to increase production. Background technique [0002] At present, nitrogen (gas) injection in oil and gas fields has been widely used in carbonate reservoirs and heavy oil reservoirs at home and abroad, and has achieved certain results. [0003] In order to solve problems such as clogging of oil reservoirs, high viscosity of heavy oil, and increase of oil washing capacity during nitrogen injection production stimulation construction, it is often necessary to use chemical additives with functions such as plugging removal, viscosity reduction, and oil washing. [0004] Chemical additives are generally injected into the formation at one time in front or injected into the formation with nitrogen slugs. Under the formation conditions, due to different fluids (crude oil...

AI Technical Summary

Problems solved by technology

[0004] Chemical additives are generally injected into the formation at one time in front or injected into the formation with nitrogen slugs. Under the formation conditions, due to different fluids (crude oil, chemical additives, water, gas) The slug effect makes it difficult for them to mix uniformly, making it difficult for most chemical additives to play a role, reducing the effect of chemical additives

[0005] The existing patent CN206980494U discloses a foam generator for high-pressure oil and gas well operations, including an inlet pipe, a first cock valve, a one-way valve, a propeller, a spiral stirring block, a thickened high-pressure resistant main pipe, a foam fluid discharge pipe, The second cock valve, the liquid inlet pipe, the third cock valve, one end of the thickened high-pressure resistant main pipe is connected to the inlet pipe, the first cock valve and the one-way valve are installed in the inlet pipe, and the liquid inlet pipe is arranged next to the inlet pipe. A second cock valve is installed on the liquid inlet pipe; the other end of the thickened high-pressure resistant main pipe is provided with a foam fluid discharge pipe, and the left end of the foam fluid discharge pipe communicates with the thickened high-pressure resistant main pipe, and the lower end of the foam fluid discharge pipe There is a liquid diversion pipe between the outlet and the liquid inlet pipe on the side; a propeller and a spiral stirring block are installed in the inner cavity of the thickened high-pressure resistant mother pipe, and the nitrogen gas entering the intake pipe is cut by the propeller, and uniform foam is formed by the spiral stirring block , this kind of foam generator can form nitrogen and chemical additives into foam for oil and gas field stimulation, but it cannot atomize chemical additives
