Abstract
The utility model discloses a well drilling liquid-gas separator which is a well drilling liquid-gas separator used during under-balance well drilling and overcomes the disadvantages existing in other technologies. The separator adopts the following structure: a liquid inlet arranged inside a tank is provided with a cyclone; a liquid outlet pipe and a tank body are formed into a U-type structure; the liquid outlet pipe, a blow-off pipe and the tank body are formed into a tee-junction structure; an impact plate is provided with an air pipe; an exhaust pipe arranged inside the tank is provided with an exhaust screen; the tank body is provided with a support supporting the cyclone; moreover, a safety valve is arranged at the top end of the tank body. The separator obviously reduces the possibility that the air is polluted by the gas, and improves separation effect; moreover, the separator ensures complete separation of slurry and gas as well as a smoother ascending channel for the gas.
Description
One, technical field: the utility model relates to a kind of drilling fluid-gas fractionation unit that uses, especially drilling fluid----gas separator in the under balance pressure drilling process.
Two, background technology: at present, in the drilling prospection process, the drilling fluid-gas separator of use generally comprises tank body, feed tube, drain pipe, stack and liquid gas and separates crash panel, mainly has the following disadvantages.
Complex structure, safety factor is low: overflow from drain pipe for preventing gas, two kinds of methods are generally arranged, a kind of is that a float-ball type valve is installed on jar, Pneumatic butterfly valve is installed, float-ball type valve closing when liquid level is low, gas circuit sealing on drain pipe, Pneumatic butterfly valve is closed, and the drilling fluid after the separation is stored in the bottom of jar; When liquid level rises to certain altitude, ball float rises, gas circuit is communicated with, and Pneumatic butterfly valve is opened, and drain pipe begins discharge opeing, in order to guarantee that certain liquid is arranged in the jar, float-ball type valve and Pneumatic butterfly valve can be frequent unlatching, close, be easy to damage, cause the well site can't operate as normal, environment is polluted, and serious also might cause casualties.Another kind is on the next door of main tank body a liquid level equilibrium jar to be installed, though this structure can prevent that gas from entering drain pipe, the structure more complicated.
Drilling fluid-gas separates not thorough: only by the bump of crash panel the gas in the drilling fluid is smashed, separating effect is bad; Alternately install about crash panel, the gas rising passway after the separation is not smooth.
Three, summary of the invention: the purpose of this utility model is to provide a kind of simple in structure, easy to maintenance, safe and reliable drilling fluid---gas separator, it has overcome the shortcoming that other technology exists, the purpose of this utility model is to realize like this, it is to be formed by connecting by feed tube, swirler, exhaust screen, stack, crash panel, drain pipe, tank body, safety valve and blow-off pipe, and swirler is installed at the inlet place in jar; Drain pipe becomes U type structure with tank body, drain pipe, blow-off pipe become three-port structure with tank body; Crash panel is provided with ventilating pipe; On the jar inside exhaust pipe exhaust screen is installed; Tank body is provided with the support that supports swirler; Safety valve is installed in the top of tank body.
Operating principle of the present utility model is: drilling fluid in feed tube enters tank body after, be introduced into swirler, gas after the separation rises, and is discharged by stack, and heavy drilling fluid is discharged by the swirler bottom, continue the shock plate and separate residual gas in the drilling fluid, the ventilating pipe that gas prolongs on the crash panel rises, and discharges from the stack at tank body top, is transported to the processing of burning at a distance, drilling fluid after the separation is discharged from drain pipe, is transported to mud pit.Because drain pipe becomes U type structure with tank body, so played the effect of liquid level equilibrium, make to remain a certain amount of drilling fluid in the tank body that drilling fluid blocks the fluid mouth of pipe, prevent that gas from discharging from drain pipe, obviously reduced the possibility of gaseous contamination environment.The utility model can save pneumatic dish valve of the prior art, float-ball type valve and liquid level equilibrium pipe, and this not only provides cost savings, and has prolonged application life.In case it is too high that the tank body internal pressure takes place, safety valve is opened release pressure, guarantees the safe in utilization of equipment.
Owing to adopted technique scheme, this use is novel to have following advantage:
1, drain pipe becomes U type structure with tank body, and remaining has a certain amount of mud liquid in the tank body, prevents that gas from discharging from drain pipe, has reduced the possibility of gaseous contamination air significantly.
2, inlet has been installed swirler, has improved separating effect.
3, established ventilating pipe on the crash panel, it not only makes mud liquid more thoroughly separated from the gas, and guarantees that the rising passway of gas is more unobstructed.
4, drain pipe, blow-off pipe become three-port structure with tank body, therefore, open valve in the time of in the purge tank, and sewage is discharged from sewage draining exit.
5, exhaust pipe mouth is provided with baffle plate, and having prevented that mud from splashing influences exhaust in the stack.
Four, description of drawings: Fig. 1 is a drilling fluid--the front view of-gas separator, and among the figure: 1, feed tube 2, swirler 3, exhaust screen 4, stack 5, crash panel
Fig. 2 is a drilling fluid--the left view of-gas separator, among the figure 6, drain pipe 7, tank body 8, safety valve; 9, blow-off pipe
Five, the specific embodiment: in Fig. 1 and Fig. 2, swirler 2 is installed at the inlet place of feed tube 1 in jar; 7 one-tenth U types of drain pipe 6 and tank body structure, drain pipe 6,7 one-tenth three-port structures of blow-off pipe 9 and tank body; Crash panel 5 is provided with ventilating pipe; On the jar inside exhaust pipe 4 exhaust screen 3 is installed; Tank body 7 is provided with the support that supports swirler 2.
