UNIDIRECTIONAL BASE HYDRAULIC PUMPING APPARATUS FOR INCREASING THE RE-INJECTION/INJECTION FLOW OF FORMATION WATER IN OIL WELLS

摘要

The invention relates to a unidirectional base hydraulic pumping apparatus for use in oil wells, which is installed at the depth desired by the user in order to increase the flow of formation water to be re-injected/injected from a storage tank at the surface to the deposit sands and the necessary areas. The surface pump injects through the production piping a flow of formation water, which passes through the spout of the hydraulic pumping apparatus of the present invention, generates a Venturi effect, producing the pressure differential which draws the stored formation liquid by gravity into the annular space between the production piping and the lining pipes. In this way, the flow thus drawn in is added to the flow from the main piping, considerably increasing the total re-injection flow, without the need to increase the number of pumps at the surface.
