Abstract
The utility model relates to a kind of pipe bit completion technique field, particularly a kind of continuous-tube liner completion process pipe string releasing device continuously.The piston rod of the electromagnetic valve main body of this device is connected with piston, the upper end tube wall of extension hanger is set with outside the lower end tube wall of electromagnetic valve main body, the lower end tube wall of electromagnetic valve main body and the upper end tube wall of extension hanger are installed from lock ball, block from lock ball in the lower end tube wall that piston is placed in electromagnetic valve main body, sealed by O RunddichtringO between the lower end tube wall of piston and electromagnetic valve main body.The utility model achieves continuous-tube and tail pipe hanger safety is given up smoothly.Overcome existing releasing tool and can not realize the deficiency that continuous-tube and tail pipe hanger safety give up smoothly.
Description
Technical field:
The utility model relates to a kind of pipe bit completion technique field, particularly a kind of continuous-tube liner completion process pipe string releasing device continuously.
Background technology:
At present, continuous pipe bit completion technique is widely used in sidetracked hole abroad, has domesticly also carried out the research of continuous pipe bit well-completing process and instrument in recent years successively.Due to the not revolvable particularity of continuous-tube, there is very large difference in the mode of giving up of its extension hanger and conventional tool mode.
The conventional sidetracked hole liner completion mode of giving up mainly contains following several:
(1) utilize upper drilling string to rotate and open extension hanger feeding left-hand tool joint, realize giving up;
(2) mode utilizing pitching to build the pressure opens stop collar, above carries drilling tool and realizes giving up.
In continuous-tube liner completion technology, routine mode of giving up all can not realize, and reason is as follows:
(1) continuous-tube can not rotate;
(2) continuous-tube is due to built-in cable, can not pitching or throwing plug.
For above problem, have developed a kind of releasing device of continuous-tube liner completion process pipe string, it is very necessary for realizing that continuous-tube and extension hanger put aside smoothly.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of continuous-tube liner completion process pipe string releasing device, the arrangement achieves continuous-tube and tail pipe hanger safety is given up smoothly.Overcome existing releasing tool and can not realize the deficiency that continuous-tube and tail pipe hanger safety give up smoothly.
Technical solution adopted in the utility model is: a kind of continuous-tube liner completion process pipe string releasing device, comprises electromagnetic valve main body; The piston rod of electromagnetic valve main body is connected with piston, the upper end tube wall of extension hanger is set with outside the lower end tube wall of electromagnetic valve main body, the lower end tube wall of electromagnetic valve main body and the upper end tube wall of extension hanger are installed from lock ball, block from lock ball in the lower end tube wall that piston is placed in electromagnetic valve main body, sealed by O RunddichtringO between the lower end tube wall of piston and electromagnetic valve main body.
The beneficial effects of the utility model are: the utility model achieves continuous-tube and tail pipe hanger safety is given up smoothly.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
As shown in Figure 1, a kind of continuous-tube liner completion process pipe string releasing device, comprises electromagnetic valve main body 1; The piston rod of electromagnetic valve main body 1 is connected with piston 2, the upper end tube wall of extension hanger 5 is set with outside the lower end tube wall of electromagnetic valve main body 1, the lower end tube wall of electromagnetic valve main body 1 and the upper end tube wall of extension hanger 5 are installed from lock ball 4, block from lock ball 4 in the lower end tube wall that piston 2 is placed in electromagnetic valve main body 1, sealed by O RunddichtringO 3 between the lower end tube wall of piston 2 and electromagnetic valve main body 1.
During use, electromagnetic valve main body 1 drives piston 2 to move upward, and when all exposing from lock ball 4, from lock ball 4 automatic unlocking, carrying continuous-tube and namely completing action of giving up now.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
