Embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combination.Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
The utility model provides a kind of leakage-proof hot washing structure.
In the utility model and embodiment of the present utility model, leakage-proof hot washing structure is used for open-hole horizontal well completion partial pressure
In tubing string.Completion partial pressure tubular column includes hanging packer, and the top of hanging packer has sealing drum 1.
In embodiment of the present utility model, in order to solve the problem of hot wash liquid of the prior art is missed, to leakage-proof hot washing
Structure is improved, specifically described below：
As depicted in figs. 1 and 2, in the present embodiment, leakage-proof hot washing structure includes body 10 and check configuration.Body 10 has
Head and afterbody, head are stretched into sealing drum 1, and are connected with sealing drum 1, and afterbody is located at outside sealing drum 1.Check configuration is arranged on
On body 10.Wherein, when the liquid in sealing drum 1 enters the head of body 10, liquid enters body 10 by check configuration
Afterbody, when hot wash liquid enters body 10 from the afterbody of body 10, check configuration backstop hot wash liquid enters the head of body 10.
By above-mentioned setting, liquid can be extracted out in oil recovery process by check configuration out of well, realize normal production；
Meanwhile, hot wash liquid can will not enter the horizontal segment of sealing drum and horizontal well in hot wash operation by unidirectional structure barrier, so that
Realize leakage-proof hot washing function.
Specifically, because leakage-proof hot washing structure includes body 10 and the check configuration being arranged on body 10, progress is worked as
During normal production, the liquid in sealing drum 1 can be entered in body 10 by the head of the body 10 connected with sealing drum 1, and to
Check configuration applies the pressure from head to caudal directions.When check configuration is by pressure along above-mentioned direction, liquid can
Enter the afterbody of body 10 by check configuration, so as to realize oil pumping operation.And when need carry out hot wash operation when, hot wash liquid from
The afterbody of body 10 enters in body 10, and applies the pressure from afterbody to cephalad direction to check configuration.When check configuration by
During to pressure along above-mentioned direction, it will backstop hot wash liquid enters the head of body 10, it is to avoid hot wash liquid enters to be connected with head
Sealing drum 1 in, so as to avoid the generation of hot wash liquid leakage phenomena.Further, check configuration backstop hot wash liquid enters
Net horizontal section, so as to be conducive to hot wash liquid to be extracted out by pumping pipe string, sets up the circulation of hot wash liquid.Therefore, leakage-proof hot washing structure one
Aspect causes hot wash liquid energy enough to set up circulation so that well-flushing is more thorough；On the other hand avoiding hot wash liquid enters stratum, it is ensured that
Stratum will not be contaminated.
As shown in Fig. 2 in the present embodiment, check configuration includes plugging structure 21 and coordinate with plugging structure 21 first
Stopper section 22.First stopper section 22 is arranged on body 10, and the first stopper section 22 has overcurrent mouth 2211.Wherein, plugging structure
21 have open position and closed position, when pressure of the plugging structure 21 by liquid, and plugging structure 21 is located at open position
To avoid overcurrent mouth 2211；When pressure of the plugging structure 21 by hot wash liquid, plugging structure 21 is located at closed position to block
Overcurrent mouth 2211.
By above-mentioned setting, there is overcurrent mouth 2211 on the first stopper section 22 on body 10, body 10 can be connected
Head and afterbody, form liquid crosses liquid passage.Plugging structure 21 is included due to check configuration and coordinated with plugging structure 21
The first stopper section 22, plugging structure 21 have avoid overcurrent mouth 2211 open position and closure overcurrent mouth 2211 close stance
Put, therefore, in oil recovery process, plugging structure 21 is located at open position under the pressure effect of liquid, to connect in body 10
Cross liquid passage, realize normal production；In hot wash operation, plugging structure 21 is located at close stance under the pressure effect of hot wash liquid
Put, to block the liquid passage excessively in body 10, prevent hot wash liquid from entering in sealing drum 1, so as to realize the liquid passage excessively of body 10
One-way flow.
Specifically, as shown in Fig. 2 in the present embodiment, in order to improve the sealing of plugging structure 21, being tied while being easy to block
Structure 21 switches between open and closed positions, and plugging structure 21 is ball sealer.Said structure is simple, and production cost is low.
Pass through above-mentioned setting, on the one hand, ball sealer has the sectional dimension of gradual change, can reliably be sealed with the first stopper section 22
Stifled overcurrent mouth 2211；On the other hand, the paraffin content height of fine and close oil is, it is necessary to periodically carry out hot-washing wax remover, and the hot-washing wax remover cycle is shorter,
Ball sealer can between open and closed positions switch under the fluid pressure effect of different directions, be adopted in order to realize
Oily operation and the switching of hot wash operation.
Preferably, ball sealer is hollow stainless steel ball.It can prevent hot wash liquid or liquid from causing using hollow stainless steel ball
Ball sealer corrosion, so that avoid closure from failing, and hollow stainless steel ball lighter weight, it can be ensured that pressure of the ball sealer in liquid
Power effect is lower to be located at open position.
As shown in Fig. 2 in embodiment of the present utility model, the first stopper section 22 includes annular slope structure 221, circular slanting
Direction of the face structure 221 along afterbody to head is gradually tapered up to the axis of body 10, annular slope structure 221 close to head one
End forms overcurrent mouth 2211.
Because the first stopper section 22 includes annular slope structure 221, direction of the annular slope structure 221 along afterbody to head
Gradually tapered up to the axis of body 10, therefore, in the case where hot wash liquid is along afterbody to the active force of cephalad direction, outside plugging structure 21
Surface can be pushed against with the inner surface of annular slope structure 221, so as to block one end in annular slope structure 221 close to head
Overcurrent mouth 2211 is formed, reliable sealing is realized in hot wash operation.
Further, when plugging structure 21 is ball sealer, with annular slope structure 221 when ball sealer is in the closed position
Linear contact lay is formed, reliable closure can be realized, the contact area of ball sealer and the first stopper section 22 can be reduced again, it is to avoid closure knot
Structure 21 is stuck in the problem of can not being switched to open position in the first stopper section 22, and this improves the reliable of leakage-proof hot washing structure
