Abstract
The utility model relates to a shock-proof device of a deep well testing instrument, which solves the problem of the damage of the testing instrument caused by the shock of a drilling pole of a high-temperature hard stratum of a deep well. The utility model is characterized in that the ladder surfaces of both ends of the testing instrument (5) are respectively provided with a vulcanized rubber spring (4) and a double-layer spring (3), and both ends of an outer barrel (1) are respectively and fixedly provided with a testing transfer short joint (2) and a conical dead block (6). The shock-proof device of the deep well testing instrument can meet the requirements of the problem of the shock reduction of the deep well testing instrument under various adverse industrial and mining conditions, guarantee the accuracy and the reliability of datum which are tested by the instrument, and extend the service life of the instrument.
Description
Technical field:
The utility model relates to oil drilling with the corollary apparatus that bores with the downhole testing instrument, belongs to deep-well downhole testing instrument antishock device.
Background technology:
In Process of Oil Well Drilling, tester will enter into the down-hole with drill bit, comes the data parameters under the measuring well.The design of earthquake resistant structure is generally all arranged with tester under the drilling well, mainly pass through various springs, rubber etc. as main vibration-absorptive material.But these vibration-absorptive materials can cause the inefficacy of vibration-absorptive material owing to be subjected to the long-time immersion of underground high-temperature drilling liquid, thereby, lose the effect of damping.Like this, drill string produces strong vibrations in drilling process, can cause the damage of tester, can't test downhole data.
The utility model content:
In order to overcome the problem that existing deep-well high temperature hard formation drill string vibration causes tester to damage.The utility model provides a kind of deep-well downhole testing instrument antishock device, and the vibration problems of deep-well downhole testing instrument can effectively be subdued and solve to this device, guarantees the accuracy and the reliability of instrument test data, prolongs the application life of instrument.
Technical solution adopted in the utility model is: this deep-well downhole testing instrument antishock device comprises urceolus and tester, tester places in the urceolus, the cascaded surface at tester two ends is equipped with vulcanized rubber spring and double-layer spring respectively, and respectively intrinsic test transmission short circuit in urceolus two ends and taper are extremely stifled.
The beneficial effects of the utility model are: because this deep-well downhole testing instrument antishock device, two ends at tester are equipped with vulcanized rubber spring and double-layer spring respectively, make tester and drill string be separated, apparatus subject directly is not subjected to the immersion of high-temperature drilling liquid, has played the effect of high temperature resistance; Vulcanized rubber spring and double-layer spring absorbing vibration, play step by step, the effect of dual absorbing vibration, satisfy the damping problem of down-hole tester under the various abominable industrial and mineral conditions, guaranteed the accuracy and the reliability of instrument test data, prolonged the application life of instrument.
Description of drawings:
Fig. 1 is that structure of the present utility model is partly cutd open figure.
1-urceolus among the figure, 2-transmits short circuit, the 3-double-layer spring, 4-vulcanized rubber spring, the 5-tester, the 6-taper is extremely stifled.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1, a kind of deep-well downhole testing instrument antishock device comprises urceolus 1 and tester 5, and tester 5 places in the urceolus 1, the cascaded surface at tester 5 two ends is equipped with vulcanized rubber spring 4 and double-layer spring 3 respectively, and short circuit 2 is transmitted in the respectively intrinsic test in urceolus 1 two ends and taper extremely blocks up 6.
In actual use, this deep-well downhole testing instrument antishock device, with drill bit G.I.H together, the data under tester 5 testing wells in the device.Because tester 5 is installed in the deep-well downhole testing instrument antishock device, and not isometric double-layer spring 3 is placed at the instrument two ends respectively, and vulcanized rubber spring 4 is enclosed within the instrument two ends, reach the sealing cushioning effect, make apparatus subject directly not be subjected to the bubble of invading of high-temperature drilling liquid, play the effect of high temperature resistance.This deep-well downhole testing instrument antishock device can satisfy the damping problem of down-hole tester under the various abominable industrial and mineral conditions, has guaranteed the accuracy and the reliability of instrument test data, has prolonged the application life of instrument.
Claims (1)
1, a kind of deep-well downhole testing instrument antishock device, comprise urceolus (1) and tester (5), tester (5) places in the urceolus (1), it is characterized in that: the cascaded surface at tester (5) two ends is equipped with vulcanized rubber spring (4) and double-layer spring (3) respectively, and short circuit (2) is transmitted in the respectively intrinsic test in urceolus (1) two ends and (6) are extremely blocked up in taper.
