Abstract
The utility model relates to a wired integrated inclinometer during drilling, which is provided with a column damper which is fixedly connected with a probe at axial direction and can tightly support the inner wall of a compression resistant outer cylinder at peripheral direction, and the lower end of the inclinometer probe is provided with a joint combiner. The utility model realizes integration structure of the inclinometer and the compression resistant outer cylinder, which not only can cause the whole length to be shortened, but also cause the whole assembling time of the inclinometer to be greatly shortened.
Description
The utility model belongs to detecting devices field, down-hole, oil field, specially refers to the integrated deviational survey instrument that is used for wired drilling.
In the oil field is surveyed, the use of steering tool has the history of decades, for a long time, the production of this Wired System for Inclination Measurement and use, all be based on a kind of state that inclinometer is separated with its resistance to compression urceolus, the product of this inclinometer is very tediously long, complicated, total length reaches 9 meters more than, inserting tube complex structure not only in the former inclinometer, and have between inclinometer and its urceolus inevitably than big gap, in the wired drilling operation process, especially under the situation of environment very severe, just exist by a relatively large margin during use and random impact, very adverse influence is arranged this application life to instrument, usually each manufacturer the highlyest provides 200 hours to the mean free error time of wired drilling, wishes in the use that this numerical value improves as far as possible, and wishing that design is a kind of can be to reduce impact injury, features simple structure, assembling, change all integral structure very easily, alleviate the impact in the use, increased the life-span.
The purpose of this utility model is for a kind of incorporate apparatus structure is provided, and it is very tediously long, complicated to make it can overcome the existing procucts structure, has bigger defectives such as vibration gap.And redesigning a kind of features simple structure, assembling, replacing be the integral structure of easy realization all.
The utility model relies on following technical proposals to realize, the integrated deviational survey instrument of a kind of wired drilling, comprise inclinometer axis body, resistance to compression urceolus, inserting tube and terminal part, it is characterized in that, one section cylindricality shock absorber is set, it is axially being fixedlyed connected with inserting tube, and the inside wall that can tightly support the resistance to compression urceolus in peripheral direction is fixed into one with it; Be provided with the contact combiner in the lower end of inclinometer probe.
At first adopted the shock absorber length that totally shortens dramatically, in original inclinometer, there is the gap in the resistance to compression urceolus of inserting tube and outside, the position of shock absorber is one section very long spring, make whole instrument tediously long, the position of contact combiner also is nonadjustable fastening devices relation, and after integrated, contact combination place is tie cable directly.In use, integrated deviational survey instrument upper end can directly connect extension bar and guide shoe, makes connection more convenient.
Good effect of the present utility model is, owing to realized the integral structure of inclinometer and resistance to compression urceolus, adopt axially and vibration absorber radially, reduce with stifled and cut off the impulsion that causes the original interstice and the harmful effect in application life, and, because simplified structure, entire length is shortened, the multi pack time of inclinometer is shortened dramatically, reduced to present 30 minutes by former about 2 hours, compress the oil field and used the operating time, also reduced the use cost in oil field.
Further specify embodiment below in conjunction with accompanying drawing:
Description of drawings: Fig. 1, integrated deviational survey instrument structural representation.
Among the figure, inclinometer body 1 is a major axis cylindricality, its periphery is a resistance to compression urceolus 2, what tightly be supported on inner radius is one section cylindricality shock absorber 3, the material of shock absorber can be selected rubber and elastic organic material for use, inserting tube 4 is fixedly connected on its below, and the inserting tube bottom is provided with the contact combiner 5 of adjustable spring, is terminal part 6 below.Incorporate dip circle structure can make overall length shorten more than 2 meters.
Claims (6)
1, a kind of wired drilling body one is changed inclinometer, comprise inclinometer axis body, resistance to compression urceolus, inserting tube and terminal part, it is characterized in that, one section cylindricality damper is set, it is axially being fixedlyed connected with inserting tube, the inside wall that can tightly support the resistance to compression urceolus in peripheral direction is fixed into one with it, be provided with the contact combiner in the lower end of inclinometer probe.
2, according to the described integrated deviational survey instrument of claim 1, it is characterized in that the material of shock absorber can be selected rubber and elastic organic material for use.
