Abstract
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.
Description
Technical field
The utility model belongs to the device of desanding between sand well well head and oil pipeline, particularly a kind of oil-collecting desander.
Background technology
At present, oil field desanding method mainly contains: gravitational sand settling bag method, Swirling flow sand-removing method and filter three kinds of desanding methods.Its using method is installed sand setting bag at well mouth of oil well conventionally, but this method desanding efficiency is low, and labour intensity is large, and cost is higher.
Summary of the invention
The technical problems to be solved in the utility model is the above-mentioned defect that how to overcome prior art, and a kind of oil-collecting desander is provided, and this oil-collecting desander desanding efficiency is high, and labour intensity is little, and cost is low.
For solving the problems of the technologies described above, this kind of oil-collecting desander, comprises separator tube, and separator tube left end is provided with the fluid inlet tubes communicating with separator tube inner chamber, and fluid inlet tubes is provided with inlet valve; Separator tube upper end connects connected pipes line, and oil pipeline entrance point connects screen casing, and screen casing is arranged on separator tube inside; Separator tube bottom connects and is connected with sand setting bag, and sand setting bag bottom opening connects sediment outflow pipe, and sediment outflow pipe is provided with atmospheric valve; Separator tube right-end openings place connects plug.
So design, effectively solves the problem that desanding efficiency is low.In the time that the inlet valve of fluid in fluid inlet tubes enters separator tube, flow velocity reduces, and prop-carrying capacity weakens, sink down in sand setting bag by gravity, atmospheric valve from sediment outflow pipe is discharged, and the fluid after sand setting filters and enters oil pipeline through screen casing, and the foreign material under filtering sink to again in sand setting bag.In the time needing pipeline purging, wellhead venting, unload the plug at separator tube right-end openings place, connecting line is implemented.
As optimization, the internal diameter of separator tube is 100-150mm.So design, reasonable in design, science, and be convenient to processing.
As optimization, screen casing is arranged on the center of separator tube.So design, result of use is better.
A kind of oil-collecting desander of the utility model, simple in structure, design science, easy to use, there is desanding efficiency high, labour intensity is little, low cost and other advantages.
