Background technology
At present, logger underground probe power many employings hydraulic power, such as conventional backup probe, backup is popped one's head in ensure that instrument reaches pressure internal and external equilibrium in down-hole, backup probe the inside and outside of body has been each filled with hydraulic oil, if but measure the inside of backup probe body when card met by instrument in down-hole and be easy to build the pressure, thus causing drawing the problem that instrument is proposed well head by pushing device in.
Summary of the invention
This utility model provides a kind of safe release device of downhole instrument, overcome the deficiency of above-mentioned prior art, it can effectively solve the inside of backup probe body when card met by measuring instrument device in down-hole and be easy to build the pressure, thus causing drawing the problem that instrument is proposed well head by pushing device in.
The technical solution of the utility model is realized by following measures: a kind of safe release device of downhole instrument, including top connection, lower contact and safety pin;The inside of top connection and lower contact is respectively arranged with the upper circulation passage communicated up and down and lower circulation passage, it is provided with annular groove in top connection bottom outside upper circulation passage, the top of the medial wall of upper annular groove is provided with upper limit boss, the mounting groove communicated with lower circulation passage it is provided with in the top of lower contact, on the downside of the inwall of upper annular groove, fitted seal is sleeved on the inwall of mounting groove, spacing, top connection and lower contact is had to be fixedly installed togather by least one safety pin between bottom upper annular groove inwall and bottom mounting groove.
Further optimization and/or improvements to above-mentioned utility model technical scheme are presented herein below:
It is provided with sealing ring mounting groove on the downside of the inwall of above-mentioned upper annular groove, O RunddichtringO is installed in sealing ring mounting groove.
It is integrally formed with lower limit boss on the downside of the outer wall of above-mentioned upper annular groove, the upper outside of lower contact is sleeved in lower limit boss, top outer in lower contact is fixed with connection land, is integrally fixed with, on the upper end outer wall connecting land, the hanging platform being sleeved on top, annular groove lateral wall.
The lower outside of above-mentioned lower contact be provided with top connection bottom the land that offsets.
This utility model reasonable and compact in structure, easy to use, pressure release is highly reliable, when measuring instrument, when card is met in down-hole, the hydraulic oil in this utility model can quick pressure releasing in down-hole, it is to avoid measures the inside of backup probe when card met by instrument in down-hole and easily builds the pressure and cause that cannot draw pushing device in proposes the accident of well head by instrument.
Accompanying drawing explanation
Accompanying drawing 1 looks sectional structure schematic diagram for master of the present utility model.
The duty master that accompanying drawing 2 is after measuring instrument probe lower tube body when card is met in down-hole and be descending looks sectional structure schematic diagram.
Coding in accompanying drawing is respectively as follows: 1 for top connection, and 2 is lower contact, and 3 is upper circulation passage, and 4 is lower circulation passage, and 5 is upper annular groove, 6 is upper limit boss, and 7 is lower limit boss, and 8 for connecting land, and 9 is hanging platform, 10 is land, and 11 is safety pin, and 12 is mounting groove, and 13 is O RunddichtringO.
Detailed description of the invention
This utility model, not by the restriction of following embodiment, can determine specific embodiment according to the technical solution of the utility model and practical situation.
In this utility model, for the ease of describing, the Butut mode that the description of the relative position relation of each parts is all according to Figure of description 1 is described, as: the position relationship of upper and lower, left and right etc. is based on what the Butut direction of Figure of description 1 was determined.
Below in conjunction with embodiment and accompanying drawing, this utility model is further described:
As shown in accompanying drawing 1,2, the safe release device of this downhole instrument includes top connection 1, lower contact 2 and safety pin 11;The inside of top connection 1 and lower contact 2 is respectively arranged with the upper circulation passage 3 communicated up and down and lower circulation passage 4, it is provided with annular groove 5 in top connection 1 bottom outside upper circulation passage 3, the top of the medial wall of upper annular groove 5 is provided with upper limit boss 6, the mounting groove 12 communicated with lower circulation passage 4 it is provided with in the top of lower contact 2, on the downside of the inwall of upper annular groove 5, fitted seal is sleeved on the inwall of mounting groove 12, spacing, top connection 1 and lower contact 2 is had to be fixedly installed togather by least one safety pin 11 between bottom upper annular groove 5 inwall and bottom mounting groove 12.
According to actual needs, the safe release device of above-mentioned downhole instrument can be made further optimization and/or improvements:
As shown in accompanying drawing 1,2, on the downside of the inwall of upper annular groove 5, it is provided with sealing ring mounting groove, O RunddichtringO 13 is installed in sealing ring mounting groove.O RunddichtringO 13 material is easy to get, and it is convenient to implement;Can certainly be other sealing means such as packing_seal, adopt seal means conventional in existing known technology.
As shown in accompanying drawing 1,2, it is integrally formed with lower limit boss 7 on the downside of the outer wall of upper annular groove 5, the upper outside of lower contact 2 is sleeved in lower limit boss 7, top outer in lower contact 2 is fixed with connection land 8, is integrally fixed with, on the upper end outer wall connecting land 8, the hanging platform 9 being sleeved on top, annular groove 5 lateral wall.
As shown in accompanying drawing 1,2, the lower outside of lower contact 2 be provided with top connection 1 bottom the land 10 that offsets.
Top connection 1 in this utility model, lower contact 2 is attached by safety pin 11, top connection 1 and lower contact 2 adopt O RunddichtringO 13 to realize sealing, in this operating condition, hydraulic oil is enclosed in top connection 1 and circulation in the upper circulation passage 3 within lower contact 2 and lower circulation passage 4, when measuring instrument and meet card in down-hole and building the pressure in this utility model, as shown in Figure 2, when pressure reaches setting value, safety pin 11 is cut off, lower contact 2 comes downwards to the lower section of O RunddichtringO 13, depart from sealing surface, O RunddichtringO 13 can not realize sealing, now hydraulic oil can ooze out from the contact surface of top connection 1 with lower contact 2 and realize pressure release;Lower limit boss 7 coordinates with hanging platform 9, it is ensured that when lower contact 2 is descending, will not completely disengage between lower contact 2 and top connection 1.
Above technical characteristic constitutes most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease non-essential technical characteristic according to actual needs, meet the demand of different situations.
