A multi-medium large-displacement hydraulic injection device

Abstract

The invention discloses a multi-media large-displacement hydraulic injection device, which includes a support frame, a liquid distribution tank, a temporary liquid storage bin and a hydraulic profile control and water plugging pump. The liquid distribution tank is installed on the support frame, and the temporary The liquid storage bin is installed under the support frame and is located on one side of the liquid distribution tank, and the hydraulic profile control and plugging pump is installed on one side of the support frame. The automatic liquid dosing work is carried out regularly and quantitatively according to the design ratio, and the input of profile control agent and various auxiliary materials is carried out, and the rotary temperature control stirring mechanism is used to fully stir the input materials, so that the raw materials are fully mixed, hydraulic pressure The profile control water plugging pump pumps the profile control fluid into the wellbore. The whole liquid preparation process is rapid and continuous, with a high degree of automation and strong anti-interference ability, which greatly reduces the labor intensity of the on-site staff and improves the profile control agent. Dosing quality.

Description

technical field [0001] The invention relates to the technical field of hydraulic injection devices, in particular to a multi-media large displacement hydraulic injection device. Background technique [0002] Profile control of water injection well is to inject chemical profile control agent into the water injection well, let the profile control agent block the high permeability layer of the water injection well downhole, change the direction of water flow, and force the injected water to enter the original medium and low permeability layer, thereby expanding the injection water. Sweep volume, improve the utilization rate of injected water, after the injected water enters the medium and low permeability layers, the crude oil that has not been driven is displaced, and the oil production and staged recovery degree of the oil well are improved. From the perspective of construction technology , Chemical water plugging can be divided into single-liquid method and double-liquid met...

Problems solved by technology

[0004] The purpose of the present invention is to solve the above-mentioned problems by designing a multi-media large-displacement hydraulic injection device, which solves the problem that in the prior art, the drug metering, dosing and preparation of chemical profile control devices are all manual mode, relying on Manual operation, due to problems such as equipment differences, personnel differences, and inadequate management, the measurement errors of medicines are large, and the profile control agent prepared on site differs greatly from the scheme design formula, which seriously affects the profile control effect and success rate.
