Abstract
The utility model discloses a three-dimensional steam injection well mouth back-off, which comprises a welding short tube, an angle fitting, a connection tube, and a movable pair and a connection tube connecting the angle fittings. The other end of the angle fitting connects with the welding short tube, and the movable pair comprises an airproof cabinet, nuts which are connected on the air-proof cabinet, and the movable column jacket which is arranged in the airproof cabinet, an airproof general bearing equipped on the movable column and a binding ring and gland equipped respectively on the upper portion and the lower portion of the airproof general bearing. The three-dimensional principal structure of the utility model fits the feature of connection in any directions of the steam injection well mouth and is capable of sufficient thermal compensation to the well mouth and gas injection column jacket, and thereby being widely applied in the oil thermal production well compensation technique.
Description
One, technical field
The utility model relates to the petroleum thermal recovery wellhead equipment, particularly a kind of three-dimensional vapour well head expansion loop of annotating.
Two, background technology
The traditional well head expansion loop that uses in the petroleum thermal recovery steam injection technology, be linear type structure, its with annotate vapour well head plane and be in parallel or during the upright position, can install smoothly, also can and annotate steam pipe and compensate sleeve pipe, but its also exist simultaneously when the trend of steam injection pipeline when annotating the vapour well head and be in oblique position, the well head compensation just can't install and use, often influence normally carrying out of steam injection technology, heavy crude heat extraction is restricted.
Three, summary of the invention
The purpose of this utility model provides a kind of three-dimensional vapour well head expansion loop of annotating, and shortcoming or deficiency that it can overcome effectively or avoid existing in the above-mentioned prior art improve the effect and the range of application of well head compensation effectively.
The three-dimensional vapour well head expansion loop of annotating described in the utility model, comprise weld nipple, elbow and tube connector, also be included in the movable pair and the tube connector that connect between the described elbow, the other end of elbow is connected with weld nipple, described movable pair comprise closed chamber and on the movable tubing string installed in the nut, closed chamber that are connected and on the sealing assembly installed and sealing assembly snap ring and the pressure cap installed respectively up and down.
Wherein, described movable pair is two pairs, a pair of being connected between left elbow and the middle elbow, and by the parallel connection of tube connector, another is to being connected between middle elbow and the right elbow orthogonal installing.The closed chamber of the secondary end of described a pair of activity is connected to the tube connector two ends, and the other end is connected on left elbow and the middle elbow.Described another connects movable parafacies is vertical mutually, and an one movable secondary movable tubing string is connected with another movable secondary closed chamber, and a movable secondary closed chamber is connected with tube connector, and another movable secondary adjustable pipe tubing string is connected with right elbow.Be connected with middle elbow by tube connector between described two pairs of movable pairs.Described nut is connected with closed chamber, and its external surface is installed on the shackle handle.Described movable tubing string one end can rotatablely move as circumference in closed chamber, and the end is installed on snap ring, locatees up and down, and the other end is outside nut.
The utility model has following advantage compared with prior art:
1, owing to all adopted the activity pair that can rotate on vertical and horizontal, so activity freely, and scope is big, can rotate in three dimensions, and is easy to install;
2, be provided with HTHP sealing assembly, but heatproof up to 370 ℃, withstand voltage 21Mpa makes it more effective at the HTHP lower seal.
Four, description of drawings
Accompanying drawing is the utility model structural representation.
