Abstract
A balance-short drilling well flow-guided gas and liquid extractor mainly resolves the problem that the current ones has lower instant dealing amounts and a small discharging capacity and negative effect in extracting. The utility model is characterized in that the burning pipe on the two sides of the valve (6) passes the connecting pipe (5) which is connected in parallel with the valve (3) and flow-guided machine (4). Moreover, the extractor can handle large amount of material instantaneously, and the discharging capability has been improved and the extracting effect is very good.
Description
Technical field:
The utility model relates under balance pressure drilling field, oil field used liquid-gas separator, especially under balance pressure drilling drainage type liquid-gas separator.
Background technology:
In geological prospecting, drill drilling is an important means wherein.Compare with the drilling well of routine, the underbalance pressure drilling is meant that pressure that in drilling process drilling fluid produces in the shaft bottom is lower than the pore pressure of payzone, allow the payzone fluid to flow into well, and can be recycled to ground, can control effectively on ground and the separation of liquid gas.The purpose that liquid gas separates is that liquid is separated from the gas, and at present liquid-gas separator when gas is instantaneous when pouring in eliminator in by well, the on-way resistance that pipeline and annex produced that arrives emptying point because of the gas outlet of eliminator is big, cause that liquid gas disposal ability is low, inferior separating effect and discharge capacity be low, make gas not discharge moment, the pressure in the eliminator raises, and final gas is sprayed by U type pipe, have potential safety hazard, influence is normally crept into.
The utility model content:
The existing instantaneous treating capacity of liquid-gas separator is low in order to overcome, discharge capacity low and the deficiency of inferior separating effect, the utility model provides a kind of under balance pressure drilling drainage type liquid-gas separator, and this under balance pressure drilling drainage type liquid-gas separator has the characteristics of instantaneous treating capacity height, discharge capacity height and good separating effect.
The technical solution of the utility model is: this under balance pressure drilling drainage type liquid-gas separator comprises tank body and burning pipeline, the tank body bottom is connected with the burning pipeline, be serially connected with valve and anti backfire valve respectively on the burning pipeline, the burning pipeline at valve two ends is parallel with valve and drainage blower fan by tube connector.
The beneficial effect that the utlity model has is: because under balance pressure drilling drainage type liquid-gas separator is parallel with drainage blower fan and valve on tank body lower end burning pipeline, make by the drainage blower fan and to form certain negative pressure in the tank body, when gas is instantaneous when pouring in eliminator in by well, increased mass rate of emission, separating effect and disposal ability have been improved, can also regulate and control vacuum magnitude in the tank body by valve according to actual conditions, in guaranteeing tank body under the peak suction, can't cause the mud in the tank body to discharge, so have instantaneous treating capacity height from gas vent, the characteristics of discharge capacity height and good separating effect.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
1-tank body among the figure, the 2-pipeline that burns, 3-valve, 4-drainage blower fan, 5-tube connector, 6-valve.
The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
By shown in Figure 1, this under balance pressure drilling drainage type liquid-gas separator comprises tank body 1 and burning pipeline 2, tank body 1 bottom is connected with burning pipeline 2, be serially connected with valve 6 and anti backfire valve respectively on the burning pipeline 2, be parallel with valve 3 and drainage blower fan 4 by tube connector 5 at valve 6 two ends on the burning pipeline 2, make by drainage blower fan 4 and to form certain negative pressure in the tank body, when gas is instantaneous when pouring in eliminator in by well, can in time gas be discharged rapidly, so just increased mass rate of emission, improved separating effect and disposal ability, can regulate and control the size of the negative pressure in the tank body 1 by valve 3 according to actual conditions.
During actual the use, use the same with existing eliminator.
Claims (1)
