Detailed description of the invention
Below in conjunction with accompanying drawing and concrete embodiment, the utility model will be further described.
Embodiment one, the present embodiment proposes a kind of fireflood oil well tail gas condensing liquid trap, as shown in Figure 1-Figure 3, wherein, Fig. 1 is the front view of a kind of fireflood oil well of the present embodiment tail gas condensing liquid trap, Fig. 2 is the top view of Fig. 1, Fig. 3 is the right view of Fig. 1, comprise buffering and be separated pipeline section 10, condensation separation pipeline section 20, and liquid collecting collecting pipe 30, one end that described buffering is separated pipeline section 10 is air intake, for being communicated with fireflood oil well casing 40, other one end that described buffering is separated pipeline section 10 is communicated with described condensation separation pipeline section 20, the free end of described condensation separation pipeline section 20 is connected with gas outlet 21, be communicated with described liquid collecting collecting pipe 30 bottom described condensation separation pipeline section 20, pressure between described condensation separation pipeline section 20 and liquid collecting collecting pipe 30 is not more than 0.15 MPa.The fireflood oil well tail gas condensing liquid trap of the present embodiment, the buffering tilted by arranging at least part of segment is separated pipeline section 10, first the buffering entering inclination from the tail gas of fireflood oil well casing 40 output from bottom is separated pipeline section 10, tail gas water vapour and part light oil in uphill process tentatively condense, carry out preliminary large drop to flutter and catch separation, then tail gas after preliminary large drop catches enter condensation separation pipeline section 20, water vapour and part light oil condense on the tube wall of condensation separation pipeline section 20, pressure between described condensation separation pipeline section 20 and liquid collecting collecting pipe 30 is 0.02 ~ 0.15 MPa, after condensation accumulates large drop, drop flows in liquid collecting collecting pipe 30 under self gravitation, this fireflood oil well tail gas condensing liquid trap can realize gas-liquid quick separating, quick separating goes out water vapour and light crude oil composition in tail gas, prevent from reducing desulfurized effect.Experimentally known, when fireflood oil well casing 40 and condensation separation pipeline section 20 inlet-pressure mechanical resistance are not more than 0.15MPa, drop only can along entering in liquid collecting collecting pipe 30 by self gravitation, without the need to arranging other power recovery mechanisms, economize energy.
As a preferred embodiment, the liquid outlet of described liquid collecting collecting pipe 30 is connected with fireflood oil well casing 40 by bend pipe 31, the bend 311 at least comprising a upwards bending of described bend pipe 31, and the height of described bend 311 diapire 311a is not higher than the height of the shutoff liquid level of described liquid collecting collecting pipe 30.When the liquid imported in liquid collecting collecting pipe 30 gets more and more, when being pooled to the shutoff liquid level exceeding liquid collecting collecting pipe 30, also just in time exceed shutoff bend 311 diapire 311a, liquid is flowed in backflash by bend pipe.By arranging bend 311, not only first can collect condensed liquid component by liquid collecting pipe 30, and utilize siphon principle, can by the liquid automatic back flow in liquid collecting pipe 30 in fireflood casing 40, without the need to arranging retracting device specially in addition, save equipment cost.Conveniently industrial production manufacture, preferably, described bend pipe 31 is S shape bend pipe.
Described condensation separation pipeline section 20 comprises the some row's condenser pipes be connected, enter fireflood oil well tail gas in condensation separation pipeline section in turn at described some row's condensation Bottomhole pressure, and each row's condenser pipe moderate heat displacement of reservoir oil well tail gas all flows according to zigzag in the horizontal direction and in the vertical direction.As shown in Figure 2, for the top view of Fig. 1, to comprise two row's condenser pipes in the present embodiment, be respectively front-seat condenser pipe 20a and rear row's condenser pipe 2b, the fireflood oil well tail gas entered in condensation separation pipeline section 20 flows through front-seat condenser pipe 20a and rear row's condenser pipe 20b successively, and each row's condenser pipe moderate heat displacement of reservoir oil well tail gas all flows according to zigzag in the horizontal direction and in the vertical direction, ensure enough condensation heat collector heat exchange areas, contribute to rapid condensation and go out water vapour in tail gas and light crude oil composition, in addition, front-seat condenser pipe 20a and rear row's condenser pipe 2b can arrange again many rows respectively, can need to arrange according to actual condensation.
Described buffering is separated pipeline section 10 and comprises the tilting section 101 and horizontally disposed horizontal segment 102 that are obliquely installed, the bottom of described tilting section 101 is connected with fireflood oil well casing 40, top is communicated with wherein one end of described horizontal segment 102, and other one end of described horizontal segment 102 is communicated with described condensation separation pipeline section 20.
The inner tubal wall of described tilting section 101 is rough non-smooth structure inner tubal wall.As shown in Figure 1, along the inner tubal wall described in airflow direction, there is lug boss and depressed part, gas is when tilting section flows, fully contact with inner tubal wall, the seizure can carrying out preliminary large drop is separated the condensing pressure alleviated in subsequent condensation step, makes whole water vapour and the condensation of part light oil catch more abundant.
Described liquid collecting collecting pipe 30 comprises the horizontally disposed house steward of confluxing 301 and the vertically disposed tube connector 302 for conflux described in being communicated with house steward 301 and condensation separation pipeline section 20.Isolated for condensation separation pipeline section 20 liquid can converge by house steward 301 of confluxing, and is convenient to collect.From in Fig. 1, namely the shutoff liquid level of liquid collecting collecting pipe 30 also confluxes the height of roof of house steward 301, when the roof of liquid higher than house steward 301 of confluxing, is flowed out by bend pipe 31.
When liquid cannot be back to fireflood oil well casing 40 by bend pipe 31, the liquid level of house steward 301 of confluxing is increased to tube connector 302, when liquid level has certain altitude in tube connector, the gas distribution channel of condensation separation pipeline section 20 can be blocked, cannot normally condensation, and the air pressure that can increase in condensation liquid trap, there is certain potential safety hazard, conveniently observe the inner liquid collecting situation of liquid collecting collecting pipe 30, described tube connector 302 is provided with at least one observation window of liquid level 303, once occur liquid level rising condition, certain Prevention method can be taked, ensure liquid trap security of operation.
