Solution stirring equipment and liquid mixing system for in-depth profile control and displacement

Abstract

The invention provides solution stirring equipment and a liquid mixing system for in-depth profile control and displacement. The solution stirring equipment comprises a solution stirring tank, stirring devices, a material and solution mixing device and a delivery pipeline, wherein the stirring devices and the material and solution mixing device are all fixed at the upper end of the solution stirring tank; the delivery pipeline can deliver a solute and a solvent into the material and solution mixing device, the solute and the solvent can be mixed in the material and solution mixing device, and a mixture enters the solution stirring tank. The liquid mixing system for in-depth profile control and displacement comprises a water storage tank and multiple sets of the provided solution stirring equipment, and the water storage tank can supply the solvent to the solution stirring tanks of the solution stirring equipment through the delivery pipelines. The solution stirring equipment and the liquid mixing system for in-depth profile control and displacement have the advantages that the labor intensity of a constructor can be reduced, non-uniform solution stirring can be avoided, and the construction cost can be reduced to the greatest extent.

Description

technical field [0001] The invention relates to a liquid dispensing device, in particular to a solution stirring device and a liquid dispensing system for deep water regulating and flooding, polymer flooding and chemical flooding solutions. Background technique [0002] After more than 30 years of water injection development in Liaohe Oilfield, most of them are currently in the development stage of high water cut or extremely high water cut. The comprehensive water cut of most blocks has reached more than 90%, and the water cut of some oil wells is even as high as 98%. The recovery rate of water flooding is low. , The oil well has a high water cut, and the injected water flows along the high-permeability layer. Long-term water injection scours lead to the formation of a large amount of water flow and large pores between the oil and water wells, making it difficult to produce the low-permeability layer. Deep profile control and flooding technology is a technology aimed at imp...
