Abstract
The utility model relates to a vacuum deaerator which mainly solves the problem that the existing drilling fluid injection device can not separate the air out of the drilling fluid. The utility model is characterized in that the middle part of a vacuum tank (1) is provided with a main shaft (4) connected with a motor (3), the lower end of the main shaft (4) is connected with a shaft sleeve (6) provided with an opening (5) and sheathed out of a fluid inlet pipe (8), and the outer wall of the shaft sleeve (6) is fixedly provided with a blade wheel (7) arranged in a fluid collecting tank (9) communicated with an outlet fluid pipe (10). The vacuum deaerator can efficiently separate the air out of the drilling fluid and can be used as a stirrer. The utility model has the characteristics of simple structure and good degassing effect.
Description
Technical field:
The utility model relates to the gas fractionation unit in the drilling fluid, especially vacuum degasser in the petroleum drilling and mining process.
Background technology:
In the petroleum drilling and mining process, utilize drilling fluid (being commonly called as mud) in well, to pressurize usually, contain gas in the drilling fluid, make the proportion of drilling fluid and viscosity very unstable, influence the drillng operation quality; The device that injects drilling fluid at present in well is to utilize high-pressure pump to squeeze into the down-hole again after utilizing vacuum tank to suck drilling fluid, the gas that is contained in the drilling fluid enters the down-hole with drilling fluid, can't utilize the vacuum pump sucking-off, do not make the device that gas separates in the drilling fluid, can't separate the gas in the drilling fluid, contain a certain amount of gas in the drilling fluid to making, influence normal drilling well.
The utility model content:
The problem that can not separate the gas of drilling fluid for the device that solves existing injection drilling fluid, the utility model provides a kind of vacuum degasser, this vacuum degasser can separate the gas in the drilling fluid effectively, also can mix simultaneously device and use, have characteristics simple in structure, that degassing effect is good.
The technical solution of the utility model is: this vacuum degasser comprises vacuum tank and feed tube, vacuum tank links to each other with vacuum pump, the vacuum tank middle part is equipped with the main shaft that links to each other with motor, main shaft lower end connecting band opening and be enclosed within the outer axle sleeve of feed tube, the axle sleeve outer wall is fixed with the impeller that places in the collecting tank, and collecting tank communicates with drain pipe.
Above-mentioned motor is fixed on vacuum tank outer wall top; Main shaft places in the bearing support of loam cake of vacuum tank; Collecting tank and feed tube are fixed on the interior support of vacuum tank.
The utlity model has following beneficial effect: owing to take such scheme, the driven by motor main shaft rotates at a high speed, drilling fluid is collided the inwall of vacuum tank to injection all around by the opening on the axle sleeve, contained bubble breaking in the drilling fluid, gas is overflowed and is aspirated out by vacuum pump, and drilling fluid is discharged through drain pipe under the effect of impeller after entering collecting tank, can separate the gas in the drilling fluid effectively, also can mix simultaneously device and use, simple in structure, degassing effect good.
