Device for removing proppant deposits formed in wells after hydraulic fracturing

Abstract

The sediment of the mechanical impurities, salts, undecomposed gel, destroyed proppant is systematically accumulated after the hydraulic fracturing in the horizontal well. This process is negative for the well operation and requires additional flushing to remove sediment. If this sediment is not removed, then ultra viscous gelatinous crust is formed. The energy of the jet of the working fluid is insufficient to effectively destroy the resulting gelatinous mass in the wellbore. The paper analyzes the existing technological solutions and proposes a device developed by the authors, which allows the destruction of proppant sediments. Application of the device described in the paper will contribute to more efficient production of hydrocarbons after hydraulic fracturing
