Abstract

The invention discloses a multi-medium large-displacement hydraulic type injection device. The multi-medium large-displacement hydraulic type injection device comprises a supporting frame, a liquid distribution tank, a temporary liquid storage bin and a hydraulic profile control water blocking pump. The liquid distribution tank is arranged on the supporting frame. The temporary liquid storage binis arranged below the supporting frame, and is located on one side of the liquid distribution tank. The hydraulic profile control water blocking pump is arranged on one side of the supporting frame. Automatic liquid distributing of profile control liquid is carried out through a multi-media distribution mechanism. Profile control agents and various auxiliary materials are fed according to design proportions at regular time and in fixed quantity. Fed materials are sufficiently stirred by using a rotating temperature control stirring mechanism, and all the raw materials are fully mixed. The hydraulic profile control water blocking pump is used for pumping the profile control fluid into a wellbore, the whole liquid distribution process is rapid and continuous, the automation degree is high, the anti-interference capability is high, the labor intensity of field workers is greatly reduced, and the liquid distribution quality of the profile control agent is improved.

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...
