Description
Technical field
The present invention relates to petroleum drilling technology field, more particularly to a kind of liquid gas separation method.
Background technology
Liquid-gas separator is the equipment of the primary degassing of gas cut drilling fluid, is useful gas-mud separater, liquid qi leel
Two kinds of normal pressure and pressure self-control type can be divided into from device pressing force.
Liquid-gas separator gas cut drilling fluid enters in separator from separator inlet tangent line, falls along inwall a series of interior
On baffle plate, collision, increase exposed surface area, flow downward, cause turbulent condition, gas is separated with drilling fluid.Free gas
Discharged by the gas vent of tank deck, exhaust pipe length is determined and is equipped with by scene, and guides to safe place, and the drilling well after deaerating
Liquid is discharged into circulating tank.Liquid-gas separator is typically used together with oil field with electronic ignition device.Conventional use of liquid-gas separator
The separation of liquid gas is realized using the difference of liquid air tightness, in the case of high gas-liquid ratio, because gas often occurs in gas-liquid mixed
The phenomenon that liquid mixes out, cause separating effect bad, it is impossible to which satisfaction is actually needed.
Liquid-gas separator is matching used with choke manifold, for departing from free gas in drilling fluid, can be applied to owe
Balanced pressure drilling and the Deal With Drilling Fluid of H 2 S-containing gas.
Compared with the drilling well of routine, underbalanced logging refers to that drilling fluid is in pressure caused by shaft bottom in drilling process
Less than the pore pressure of payzone, it is allowed to which production formations fluid flows into well, and can be recycled to ground, can effectively be located on ground
Reason and liquid qi leel from.And the anti-hydrogen sulfide drilling fluid liquid-gas separator of normal pressure is manufactured using quality material, it can effectively be prevented
The erosion of pernicious gas, ensure man-machine safety in production.When drilling fluid produces gas cut, its proportion, viscosity produce larger deviation, no
Drilling well requirement can be met；If processing will cause well kick, gas blowout accident even occurs not in time when serious.
Publication No. CN 2630463, publication date are that the Chinese patent literature of on 08 04th, 2004 discloses and a kind of owes flat
Weigh drilling well diversion type liquid-gas separator, including tank body and burning pipeline, tank body lower part are connected with burning pipeline, divide on the pipeline that burns
Valve and anti backfire valve are not serially connected with, it is characterised in that：The burning pipeline at valve both ends is parallel with valve by connecting tube and drawn
Flow fan.
Publication No. CN205078204U, it is a kind of anti-that publication date is that the Chinese patent literature of on 03 09th, 2016 discloses
Stifled liquid-gas separator, including support, the support are arranged on chassis, and tank body is housed on the support, connected at the top of the tank body
Escape pipe is connected to, the tank body side is equipped with feed tube, it is characterised in that the feed tube front end is provided with the spray stretched into tank body

From；C, gassiness mud drive rotor rotate, under the action of the centrifugal force gas-liquid be layered, carry out the second not good liquor qi leel from；D, rotor revolves
Turn gassiness mud is dished out, equably shed on separation hood inwall, gassiness mud under gravity along separation hood inwall to
Lower flowing, forms very thin tubular liquid film, and gas escapes from tubular liquid film in gassiness mud, carry out third time liquid qi leel from；e、
The rotation of rotor drives the impeller being connected as a single entity with rotor to rotate, and discharges the gas inside liquid-gas separator, reduce liquid qi leel from
The internal pressure of device, separating liquid gas ", as a complete technical scheme, for prior art, pass through rotor and impeller
It is good fit, three not good liquor qi leels can be realized from being completely separated the gas in gassiness mud, whole liquid qi leel is from process operation
It is simple and reliable, there is liquid qi leel from efficiency high, the characteristics of good separating effect.
Be connected with automatic flushing device on cylinder, automatic flushing device include Flushing nozzle, flush pipe, PLC and
Flushing pump, PLC electrically connect with flushing pump, and PLC is used for start and stop flushing pump and switchs the feed liquor of liquid-gas separator
Magnetic valve and blowoff electromagnetic valve, one end of flush pipe are connected with flushing pump, and the other end is connected with Flushing nozzle, is set in flush pipe
There is ball-and-seat, after liquid-gas separator has used, PLC opens blowoff electromagnetic valve and starts blowdown, when in liquid-gas separator
Mud it is drained after, PLC starts flushing pump, and water is pumped into flush pipe through flushing pump, enters Flushing nozzle through flush pipe, logical
Cross Flushing nozzle and hydro-peening is carried out to liquid-gas separator inside, to be rinsed to finish, PLC stops flushing pump, closes blowdown electricity
Magnet valve, the auto-flushing to liquid-gas separator can be realized, prevent that the mud in liquid-gas separator is dry and hard, ensure liquid-gas separator
Stability in use, flush efficiency is high, and developing result is good.
Flushing nozzle includes nozzle boss and the horn-like nozzle with nozzle boss through connection, and is provided with horn-like nozzle
One jet pipe, the second jet pipe and the 3rd jet pipe, the second jet pipe are vertically connected at the center of horn-like nozzle, and first penetrates
Flow tube and the 3rd jet pipe, which symmetrically tilt, to be fixed on horn-like nozzle, and the water sprayed by jet pipe has higher flow velocity,
Developing result is more preferable.
