In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. Specific meanings of the above terms in the present invention and drawings in the embodiments are understood in specific cases, and technical solutions in the embodiments of the present invention are clearly and completely described, and it is obvious for those skilled in the art that the described embodiments are a part of the embodiments of the present invention, and not all of the embodiments.
The utility model is further described with reference to the following figures and specific examples.
As shown in fig. 1 and fig. 2, the timing type oil pipe inner plug of the present embodiment mainly includes a guide head 1, a central rod 2, a driving module 3, and an upper joint 4, which are arranged from bottom to top, wherein the central rod 2 is provided with a boss 21, the central rod 2 is sleeved with a sealing rubber cylinder 5 and a slip 7 from bottom to top, and the lower end of the sealing rubber cylinder 5 is in contact with the boss 21; drive module 3 is used for driving well core rod 2 and reciprocates, and drive module 3 and top connection 4 are for dismantling the connection, and top connection 4 is used for connecting the steel wire tool string, and can dismantle the change.
The main body of the driving module 3 is cylindrical, a hydraulic cylinder 31, an electric motor 32, a battery 33 and a timer 34 are arranged in the driving module 3, and the telescopic end of the hydraulic cylinder 31 is connected with the central rod 2 and can drive the central rod 2 to move up and down; an electric motor 32 is used to drive the hydraulic cylinder 31 and a battery 33 is used to power a timer 34 and the electric motor 32. The timer 34 has a timing function and also has a timing function, and can generate time consistent with the local.
Before the tool is driven into a well, a timer 34 is started by operating a touch screen 35, the starting time of the blanking plug in the timing type oil pipe is set, and then the whole blanking plug is connected with a steel wire feeding tool string through an upper connector 4. After the timing time is up, the electric motor 32 is started, the hydraulic cylinder 31 pulls the central rod 2, the central rod 2 drives the guide head 1 to move upwards, meanwhile, the boss 21 extrudes the sealing rubber cylinder 5, the sealing rubber cylinder 5 expands and seals, meanwhile, the sealing rubber cylinder 5 pushes the push cylinder 6, and the slip teeth on the slip 7 are opened and anchored on an oil pipe.
