Abstract
The utility model provides a kind of and has the stile surveying inclined function.Of the present utility model have the stile surveying inclined function, comprise tubular body, it is characterized in that: the two ends up and down of described tubular body are respectively arranged with a pair gauge head, a pair gauge head being positioned at the top of described tubular body and a pair gauge head being positioned at tubular body bottom are symmetrically distributed in the both sides of tubular body axis, each described gauge head be embedded in described tubular body inwall and by spring Bonding pressure measurement mechanism.The utility model can the inclination conditions of at-once monitor well bore in the process of creeping into, and is convenient to timely correction, ensure that the verticality of boring, improve the wellbore quality of boring.
Description
technical field:
The utility model relates to and a kind ofly has the stile surveying inclined function, belongs to earth source heat pump and develops corollary equipment technical field.
background technology:
Geothermal drilling feature is: many in 2000-3000m well depth, its heat reservori and cap rock mostly are structure Area cracked.Geothermal drilling stratum is loose, broken, interbedding of soft and hard rocks, attitude of rocks are not mild; And these distribution of strata are extensive; Geothermal drilling acquires a certain degree of difficulty.Drilling well gradient is with very much and is caused drill string wear, fatigue; Key-seating sticking; Make a trip, setting of casing difficulty; Cementing quality is poor, in order to ensure that the gradient of drilling well is in controlled scope, adopting centralizer to be enclosed within drilling rod and creeping into, avoiding the phenomenon that bit freezing occurs when borehole wall falls block, and play effective well straightening effect, guarantee carrying out smoothly of engineering.
The use of centralizer is in the wearing and tearing avoiding drilling rod to a certain extent, serve good anti-oblique effect simultaneously, but in the use procedure of reality, be subject to the impact of the many factors such as design of geologic(al) factor, drilling assembly, still inclination to a certain degree can be there is in drilling process, and existing centralizer can not the inclined degree of Timeliness coverage well bore, thus can not accomplish timely adjustment, cause final well bore control of gradient not ideal enough.
summary of the invention:
The purpose of this utility model provides a kind of for above-mentioned Problems existing to have the stile surveying inclined function, can the inclination conditions of at-once monitor well bore in the process of creeping into, be convenient to timely correction, ensure that the verticality of boring, improve the wellbore quality of boring.
Above-mentioned object is realized by following technical scheme:
There is the stile surveying inclined function, comprise tubular body, the two ends up and down of described tubular body are respectively arranged with a pair gauge head, a pair gauge head being positioned at the top of described tubular body and a pair gauge head being positioned at tubular body bottom are symmetrically distributed in the both sides of tubular body axis, each described gauge head be embedded in described tubular body inwall and by spring Bonding pressure measurement mechanism.
Described has the stile surveying inclined function, described gauge head comprises one and is embedded in described tubular body inwall can perpendicular to the pole of described tubular body inwall movement, the spring described in the connection of one end of described pole, the other end of described pole stretches out the inwall of described tubular body.
Described has the stile surveying inclined function, and the one end of described pole being stretched out the inwall of described tubular body is hemispherical.
Described has the stile surveying inclined function, and described device for pressure measurement adopts pressure sensor and is arranged on the spring base of described spring.
Described has the stile surveying inclined function, and the outer cover of described tubular body is equipped with one group of rolling bearing, described rolling bearing is installed one group of floor.
Beneficial effect:
1. centralizer of the present utility model is sleeved on drilling rod, in the process of rod boring, the gauge head at upper and lower two ends measures suffered pressure in real time, when the deviate of the pressure that superposed two gauge heads and/or two gauge heads being positioned at bottom record is larger, then can judge, drilling rod there occurs deflection, needs to correct in time, ensure that the verticality of boring, improve the wellbore quality of boring.
2. tubular body outside of the present utility model connects floor by rolling bearing, makes the rolling friction being become bearing in the process of creeping between centralizer and the borehole wall from sliding friction, creeps into more smooth and easy.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
In figure: 1, tubular body, 2, gauge head, 3, spring, 4, device for pressure measurement; 5, rolling bearing; 6, floor.
detailed description of the invention:
