Abstract
The utility model relates to the technical field of measure while drilling (MWD) vertical pipe pressure sensors, in particular to a safety shock-absorbing connector of an MWD vertical pipe pressure sensor, which comprises a high-pressure hose, a steel wire rope and adapters, wherein the adapters are respectively fixedly installed at two ends of the high-pressure hose, the steel wire rope is connected between the two adapters, and the high-pressure hose is in a curved shape. The safety shock-absorbing connector of the MWD vertical pipe pressure sensor is reasonable and compact in structure and convenient to use, and the high-pressure hose and the steel wire rope are in flexible connection. On the premise that equipment safety is guaranteed, vibration with high frequency is effectively prevented from being transmitted to the pressure sensor, vibration strength and resonant frequency are reduced, equipment resonance causing damage of the MWD vertical pipe pressure sensor is eliminated, damage of the pressure sensor is avoided, and accordingly the cost is reduced.
Description
Technical field
the utility model relates to MWD standpipe pressure sensor linkage technical field, is a kind of MWD standpipe pressure sensor safe shock-absorbing connection.
Background technology
(measurement while drilling) uses mud pulse generator that the signal of measuring is sent to ground from the down-hole usually; On the standpipe of slurry transportation, insert MWD standpipe pressure sensor; The pressure of record during mud circulation changes and receives underground signal; MWD standpipe pressure sensor commonly used adopts the diffuse si technology to produce, and poorly designed outside framework can cause the resonance frequency of pressure sensor and rig vibration source to be in step with, and the resonance of formation can cause the ceramic substrate breakage to cause; Make MWD standpipe pressure sensor scrap and can't repair, and replacement cost is high.
Summary of the invention
the utility model provides a kind of MWD standpipe pressure sensor safe shock-absorbing connection, has overcome the deficiency of above-mentioned prior art, and it can effectively solve the problem that MWD standpipe pressure sensor damages easily.
The technical scheme of
the utility model realizes through following measure: a kind of MWD standpipe pressure sensor safe shock-absorbing connection comprises high-pressure hose, wire rope and adapter; The two ends of high-pressure hose are installed with adapter respectively, between two adapters, are connected with wire rope, and high-pressure hose is bending.
Be to the further optimization of above-mentioned utility model technical scheme below or/and improve:
above-mentioned high-pressure hose and two adapters can be fixedly installed togather through screw thread respectively.
On
above-mentioned two adapters internal thread and external screw thread can be arranged respectively.
the utility model reasonable and compact in structure, easy to use, high-pressure hose and wire rope are and flexibly connect; Under the prerequisite that guarantees device security; Can effectively stop the vibration of upper frequency to be sent to pressure sensor, reduce oscillation intensity and resonance frequency, eliminate the equipment resonance that causes MWD standpipe pressure sensor to damage; Prevent that pressure sensor from damaging, thereby reduced cost.
Description of drawings
Main TV structure sketch map when
accompanying drawing 1 is the utility model and 4 and 5 installations.
Coding in
accompanying drawing is respectively: 1 is high-pressure hose, and 2 is wire rope, and 3 is adapter, and 4 is the standpipe joint, and 5 is MWD standpipe pressure sensor.
The specific embodiment
the utility model does not receive the restriction of following embodiment, can confirm concrete embodiment according to the technical scheme and the actual conditions of the utility model.
are in the utility model; For the ease of describing; The description of the relative position relation of each parts all is to describe according to the Butut mode of Figure of description 1, as: the position relation of upper and lower, left and right etc. is what to confirm according to the Butut direction of Figure of description.
Below in conjunction with embodiment and accompanying drawing the utility model is further described:
shown in accompanying drawing 1, this MWD standpipe pressure sensor safe shock-absorbing connection comprises high-pressure hose 1, wire rope 2 and adapter 3; The two ends of high-pressure hose 1 are installed with adapter 3 respectively, between two adapters 3, are connected with wire rope 2, and high-pressure hose 1 is bending.Adapter 3 links to each other through high-pressure hose 1, ties down with steel cable 2 between two adapters 3, makes high-pressure hose 1 be in case of bending; When slush pump turn on pump circulation time, high-pressure hose 1 has exceptionally straight tendency, if the while is suppressed accidents such as pump; Possibly cause high-pressure hose fracture, wire rope 2 can prevent that adapter 3 from flying out and hurt sb.'s feelings, play the security protection effect; High-pressure hose 1 and wire rope 2 are and flexibly connect; Can effectively stop the vibration of upper frequency to be sent to MWD standpipe pressure sensor 5, reduce oscillation intensity and resonance frequency, thereby prevent resonance.
Can according to actual needs above-mentioned MWD standpipe pressure sensor safe shock-absorbing connection be done further to optimize or/and improve:
Shown in accompanying drawing 1, for the ease of installation and removal, high-pressure hose 1 and two adapters 3 are fixedly installed togather through screw thread respectively
.
for the ease of installation and removal, have internal thread and external screw thread respectively on two adapters 3 shown in accompanying drawing 1.During use, two adapters 3 are linked together with MWD standpipe pressure sensor 5 through external screw thread and internal thread and standpipe joint 4 respectively.
Above technical characterictic has constituted the most preferred embodiment of the utility model, and it has stronger compliance and best implementation result, can increase and decrease non-essential technical characterictic according to actual needs, satisfies the demand of different situations.
