Description

Technical Field

[0001] The utility model relates to the technical field of oil production, in particular to a separable sub-layer oil production device. Background Art

[0002] Oil extraction refers to the act of digging and extracting oil from places where oil is stored. With the development of oil extraction technology, in order to reduce inter-layer interference and improve recovery rates, oil stratified oil production devices have emerged. Layered oil production refers to the use of packers to separate the oil layers into several layers in a production well where multiple oil layers are mined. The use of sealing or production allocation methods to reduce inter-layer interference allows the oil layers to fully play their due role.

[0003] For example, the prior art patent application number CN201020022611.3 discloses a separable, sub-layered oil production device. The upper, middle, and lower layers are separated by upper and lower packers. The upper layer's raw liquid enters the upper pump barrel cavity through the upper eccentric inlet valve, then enters the upper hollow rod through the upper dual-flow floating valve, and then enters the oil pipeline through the upper floating valve. The middle layer's raw liquid enters the lower pump barrel cavity through the lower eccentric inlet valve, then enters the upper pump plunger through the lower dual-flow floating valve, then enters the upper hollow rod through the side channel of the upper dual-flow floating valve to merge with the upper layer's crude oil. The lower layer's raw liquid enters the lower chamber of the lower pump barrel through the lower pump fixed valve, then enters the lower floating valve, the lower pump plunger, and the lower hollow rod. Then, through the side channels of the lower dual-flow floating valve and upper dual-flow floating valve, it enters the upper hollow rod to merge with the upper and middle layer's raw liquid. Together, they enter the oil pipeline through the upper floating valve, achieving separate production and simultaneous pumping.

The above-mentioned solution solves the technical problem in the prior art that the oil production device cannot be guided when it is placed in a well, resulting in the oil production device being extremely easy to contact the well wall and affecting subsequent oil production.

[0021] According to this specific embodiment, the oil production component body 101 has an interface 117, and the interface 117 is used to connect with the oil production pipe.

[0022] Among them, the fixed plate 102 is fixedly connected to the oil production part body 101, and the plurality of vertical plates 103 are fixedly connected to the fixed plate 102. The vertical plate 103 has a slide groove 118 and a guide groove 119. The slider 104 is slidably connected to the corresponding slide groove 118. The displacement plate 105 is fixedly connected to the plurality of sliders 104. Multiple groups of the abutting components are fixedly connected to the displacement plate 105. Multiple groups of the sliding components are slidably connected to the corresponding guide groove 119, and the abutting components are connected to the corresponding sliding components. The guide wheel 106 is provided on the corresponding sliding component. The force-applying component is used to drive one of the sliders 104 to move. When in use, first, according to the diameter of the oil well, the force-applying component is twisted, and the force-applying component drives the corresponding slider 104 to move. The slider 104 is moved The displacement plate 105 is moved so that the displacement plate 105 moves downward, and the displacement plate 105 drives multiple groups of the supporting components to move downward, and multiple groups of the supporting components respectively resist the corresponding sliding components to move, so that multiple groups of the sliding components respectively drive the corresponding guide wheels 106 to move, thereby enabling multiple moving wheels to contact the well wall. At this time, when the oil production component body 101 moves down into the well, it is guided by multiple guide wheels 106 to avoid the oil production component body 101 from contacting the well wall until the oil production component body 101 is lowered into the designed oil layer position in the well, and then oil production can be carried out. Similarly, it can also be guided when it is taken out to avoid contact with the well wall affecting its use. In this way, the technical problem that the oil production device cannot be guided when it is placed in the well in the prior art, resulting in the oil production device being extremely easy to contact with the well wall affecting subsequent oil production is solved.

[0023] Secondly, the two ends of the connecting rod 107 are fixedly connected to the displacement plate 105 and the supporting rod 108 respectively, and the supporting rod 108 is connected to the corresponding sliding component. When in use, the displacement plate 105 moves downward to drive the connecting rod 107 to move, and the connecting rod 107 drives the corresponding supporting rod 108 to move downward to support the sliding part.

When the supporting rod 108 moves downward, it slides in the corresponding through hole 120. When the supporting rod 108 slides in the through hole 120, it drives the force block 110 to move, and the force block 110 can drive the slide 109 to slide in the corresponding guide groove 119.

[0025] In addition, the screw 111 is rotatably connected to the corresponding vertical plate 103, the screw 111 is threadedly engaged with the corresponding slider 104, the force block 112 is fixedly connected to the screw 111, and the locking assembly is arranged on the corresponding vertical plate 103.

[0026] Again, the locking plate 116 is fixedly connected to the screw 111, and the locking plate 116 has a plurality of locking grooves 121. The support plate 113 is fixedly connected to the corresponding vertical plate 103, and the two ends of the elastic telescopic rod 114 are respectively fixedly connected to the vertical plate 103 and the locking rod 115, and the locking rod 115 is placed in the corresponding locking groove 121. When the screw 111 needs to be rotated, the elastic telescopic rod 114 is first pressed so that the locking rod 115 slides out of the corresponding locking groove 121. At this time, the locking plate 116 is no longer locked, and then the screw 111 can be rotated. After the rotation is completed, the elastic telescopic rod 114 is released. At this time, the elastic telescopic rod 114 is reset to drive the locking rod 115 to be inserted into the corresponding locking groove 121 to lock the locking plate 116 and the screw 111.

At this time, when the oil production component body 101 moves down into the well, it is guided by multiple guide wheels 106 to avoid the oil production component body 101 from contacting the well wall until the oil production component body 101 goes down to the designed oil layer position in the well, and then oil production can be carried out. Similarly, it can also be guided when it is taken out to avoid contact with the well wall affecting its use. In this way, the technical problem of the prior art that the oil production device cannot be guided when it is placed in the well, resulting in the oil production device being very easy to contact with the well wall affecting subsequent oil production is solved.
