Oil-gathering grit catcher

The utility model relates to an oil-gathering grit catcher. At present, degritting methods applied in the oil field mainly include a gravity grit deposition method, a cyclone degritting method and a filtering degritting method, and are generally implemented by a grit deposition bag at an oil well mouth, but in doing so, degritting efficiency is low, labor intensity is high and cost is high. Therefore, the oil-gathering grit catcher comprises a buffer pipe, the left end of the buffer pipe is provided with a fluid inlet pipe communicated with an inner cavity of the buffer pipe, the fluid inlet pipe is provided with an inlet valve, the upper end of the buffer pipe is penetratingly connected with an oil pipeline, an inlet end of the oil pipeline is connected with a screen pipe, the screen pipe is arranged in the buffer pipe, the bottom of the buffer pipe is penetratingly connected with a grit deposition bag, the bottom of the grit deposition bag is connected with a grit discharge pipe with a vent valve, and an opening of the right end of the buffer pipe is connected with a screw plug. The inner diameter of the buffer pipe ranges from 100mm to 150mm, the screen pipe is arranged at the center of the buffer pipe. The oil-gathering grit catcher is simple in structure, scientific in design and convenient to use and has the advantages of high degritting efficiency, low labor intensity, low cost and the like.
