Description
Technical field
The present invention relates to a kind of floating type quantitative degassers, the compound logging drilled in petroleum geology are applied, to above returning mud
Slurry carries out gas that is broken and collecting and surveying disengaging, and the invention belongs to gas logging technology apparatus fields.
Background technology
In drilling process, the oil gas in preservation rock stratum enters upper ground return table, gas logging technology in the mud of cycle and uses
Hydrocarbon information in return mud in detection and analysis infers the oil gas situation on drilling stratum.Degasser used at present is main
It has the following problems：One, degasifying effect not precisely, most of degasser uses core structure, with mud liquid level there are gap,
Contained oil gas cannot fully enter harvester after broken mud.Due to slush pump and formation influence, the upper return mud flow moment
Mud amount difference is drawn in variation every time, and the gas content of acquisition is different, seriously affects the accuracy of oil gas analysis.Two, degasser
With fluid change energy force difference, due to the influence of strata pressure and slush pump, mud liquid level floats up and down variation greatly, most degassers
By hand screw type regulating supporter or degassing cylinder height, fluid change cannot be followed in real time, if liquid level is too low, is easy to make to take off
Mechanism of qi " idle running "；If liquid level is excessively high, it is easy that mud is made to enter collecting pipe.Three, when leakage or well kick occurs, mud liquid level is prominent
So decline or reduce, personnel cannot show up in time.Four, overall structure dismounting is complicated, and equipment is heavy, and degasser is susceptible to event
Barrier, at least needs two staff, and operated on mud pool side, personal safety does not ensure.
Invention content
It is an object of the invention to overcome the shortage of prior art, a kind of floating type quantitative degasser is provided.Energy of the invention is same
Step is in close contact mud liquid level, keeps the mud for entering degassing cylinder to be in the quantitative state suitable for broken analysis, is arranged on liquid level
The safeguard measure of lower limit, preventing mud liquid level to be raised and lowered suddenly causes degasser " idle running " or slurry-sucking to enter harvester
Etc. accidents generation.
The present invention includes holder, midge head, explosion-proof constant displacement pump, two-story sedimentation case, heater, blender, fire-proof motor, list
To valve, ring baffle, conduit, grout outlet, filter, pressure gauge, anti-explosion vacuum pump, data terminal and circuit control system, branch

Device, heater are connected to degassing cylinder；
Shell, blender, fire-proof motor, check valve and ring baffle composition degassing cylinder, blender is by helical-blade, rectangle leaf
It is formed with agitating shaft, helical-blade and rectangle leaf are arranged on agitating shaft, and fire-proof motor is arranged on shell, agitating shaft and fire-proof motor
Output axis connection, check valve setting offers opposite grout outlet sum aggregate gas port on the shell, on shell, collect the position of gas port
Higher than grout outlet, ring baffle is arranged above rectangle leaf, and ring baffle is located above rectangle leaf at about cm, and ring baffle is located at
Collect below gas port and above grout outlet, the inclined angle of ring baffle is °；Grout outlet being connected to by connecting tube of degassing cylinder
The gas collection orotracheal tube of mud pit, the cylinder that deaerates is connected to filter, and filter is connected to pressure gauge, and pressure gauge is connected to explosion-proof vacuum
Pump, anti-explosion vacuum pump are connected to data processing terminal.
Circuit control system control delay limit relay, explosion-proof constant displacement pump, fire-proof motor and explosion-proof vacuum pump work, prolong
When limit relay disconnect under normal circumstances, when upper return mud liquid level is raised or lowered to certain position, midge head is also on
It rises or declines, 2~4s of Time delay limit relay delay is closed, and circuit control system judges that working condition exception, cut-out are anti-
Quick-fried constant displacement pump, fire-proof motor and explosion-proof vacuum pumping source, are stopped；Wait for that return mud build-up of fluid is normal, delay limit after
Electric appliance be delayed 2~4s disconnect, circuit control system judge working condition restore normally, be closed explosion-proof constant displacement pump, fire-proof motor and
Explosion-proof vacuum pumping source.
The heater inner wall has polytetrafluorethylecoatings coatings.
When work, the airbag aeration of midge head makes midge head float on the liquid level of upper return mud, and mud is returned in filter screen filtering
Starch the large particulate matter being mingled with；The helical-blade of blender provides mud climbing power and carries out first break, and rectangle leaf carries out the
Second-time breakage mud.
Working process and principle of the invention：
