Description
Technical field
The utility model relates to a kind of well mouth of oil well associated gas simple and efficient dryer, for removing light oil and the moisture content of oil well associated gas, is the practical well head associated gas drying device that prevents gas pipeline frozen block and oil well gas lock winter.
Background technology
Well head dryer is arranged on well mouth of oil well, and import is connected with well casing gas, and outlet is connected with gas pipe network, is a kind of to the dry device of natural gas.Because well mouth of oil well was without removing light oil, removing moisture content drying device in the past, winter temperature is low, and particularly northern area winter environment temperature is low to moderate-30
0below C, the moisture content in oil well associated gas and light oil very easily freeze to freeze and cause gas pipeline to stop up in not removed situation in gas pipeline, cause gas pipeline not smooth, and productive life air feed difficulty, affects the normal productive life in oil field.Meanwhile, gas pipeline obstruction may cause oil well to sprain and extrude existing gas lock, affect the normal production of oil well.
The rate when existence of above factor has not only affected the oil recovery of oil well to a great extent, and brought very large difficulty to the safety in production in oil field.
Summary of the invention
The purpose of this utility model is in order to prevent that moisture content not removed in associated gas and light oil from easily freezing and causing gas pipeline obstruction and oil well suppressing, gas lock in well head gas line sections, the well mouth of oil well associated gas simple and efficient dryer of research and development, guarantees that oil well normally produces and prevent that gas pipeline frozen block from affecting normal production run.
The technical solution of the utility model: well mouth of oil well associated gas simple and efficient dryer of the present utility model comprises drier enclosure cylinder, the admission line being connected with drier enclosure cylinder bottom, the pipeline of working off one's feeling vent one's spleen being connected with drier enclosure cylinder top, at the interior drying that arranges of drier enclosure cylinder 1, drying diameter is less than drier enclosure drum diameter, with drier enclosure cylinder coaxial line, drying lower openings, closed upper part, drying has spacing up and down and between drier enclosure cylinder, admission line extends to drying top, the dry separating plate of the level that arranges in the drying between admission line and drying is connected with drying, on the dry separating plate of level, there is gas-liquid separation hole, drying has spacing up and down and between drier enclosure cylinder, the dry separating plate of associated gas level in the drying cylinder of admission line top, drying end opening, the pipeline of working off one's feeling vent one's spleen that drying is connected to drier enclosure cylinder top with annular space between drier enclosure cylinder.
At drying and annular space between drier enclosure cylinder, ring drying separating plate is set and is connected with drier enclosure cylinder with drying, on ring drying separating plate, have gas-liquid separation hole.
Described ring drying separating plate is inversed taper platform shape.
Admission line in drier enclosure cylinder bottom is opened a round eye around.
Described drier enclosure drum diameter is Φ=300mm ± 10 mm, and drying diameter is Φ=150mm ± 10 mm.
Major advantage of the present utility model: the utility model volume is little, simple for production, is arranged on well head gas line sections, and the light oil in oil well associated gas can be realized separated with moisture content at well head.Adopt the roundabout one-way flow of gas, separated through multilayer separating plate, the time of staying of associated gas in dryer is long, and light oil and the moisture content removed in associated gas are thorough, and drying efficiency is high.Isolated light oil and moisture content flow back into pit shaft automatically, without manual emission, alleviate workload, reduce gas loss.This utility model efficiently solves light oil in associated gas and moisture content and easily in gas pipeline, freezes winter and to cause gas pipeline to stop up and oil well sprain pressure, gas lock problem.
