Abstract
本发明涉及一种非接触动、静态测量离散型钢管直径的传感器，由壳体(1)，凹槽(2)，隔热材料(3)，绝缘材料(4)，特殊线圈(5)，信号线导出孔(6)，保护层(7)组成，当待测钢管动态通过或静态放置在传感器的中心位置时，将会有一个唯一与钢管直径相对应的电参数出现，实现钢管直径参数与电参数的转换功能。
The invention relates to a sensor for non-contact dynamic and static measurement of the diameter of a discrete steel pipe, which consists of a housing (1), a groove (2), a heat insulating material (3), an insulating material (4), a special coil (5), The signal line lead-out hole (6) and the protective layer (7) are composed. When the steel pipe to be tested passes through dynamically or is statically placed at the center of the sensor, there will be a unique electrical parameter corresponding to the diameter of the steel pipe, and the diameter parameter of the steel pipe will be realized. Conversion functions with electrical parameters.
Description
Technical field
The present invention relates to a kind of product sensor, the sensor of the dynamic and static measurement discrete type mine locating of specifically a kind of noncontact drilling operation drill pipe diameter.
Background technology
In oil exploitation or other exploration operations, the operation of drilling rod, cease and desist order, connection between drilling rod, the position judgment of pipe collar etc. all need be known the parameter (drilling rod quantity, caliber thickness, pipe collar quantity etc.) of downhole tool, robotization when realizing operation is controlled, noncontact kinetic measurement caliber is effective and feasible means, and during due to probing, environment is badly complicated, and the temperature difference is large, interference source or chaff interference are many, and the sensor design that can complete the kinetic measurement drill pipe diameter is a larger difficult problem always.Due to the mine locating or petroleum drilling only have limited several specifications with drilling rod, therefore the present invention is only applicable to the dynamic and static measurement to the discrete type diameter of steel tube.
Summary of the invention
Technical matters to be solved by this invention is: the sensor of the dynamic and static measurement mine locating of a kind of noncontact drilling well with drill pipe diameter is provided,
The technical solution adopted for the present invention to solve the technical problems is: sensor design is: housing (1), groove (2), heat-barrier material (3); insulating material (4); special coil (5), signal wire leadout hole (6), protective seam (7).
The invention has the beneficial effects as follows, designed the sensor device of equal energy perception diameter of steel tube under a kind of dynamic and static two states, when steel pipe to be measured dynamically by or static when being placed on the center of sensor, occur having a unique electrical quantity corresponding with diameter of steel tube, realize the translation function of diameter of steel tube parameter and electrical quantity.
Description of drawings
Accompanying drawing 1 is enforcement structural representation of the present invention, and accompanying drawing 2 is orthogonal view of the present invention.
In figure: device housing (1), groove (2), heat-barrier material (3), insulating material (4), special coil (5), signal wire leadout hole (6), protective seam (7).
Embodiment
Illustrate referring to the drawings the present invention is done following concrete detailed description: as shown in Figures 1 and 2, structure of the present invention comprises housing (1), groove (2), heat-barrier material (3), insulating material (4), special coil (5), coil (5) and signal wire leadout hole (6), insulation material layer (7).It is characterized in that: sensor is by housing (1); groove (2); heat-barrier material (3); insulating material (4); special coil (5); signal wire leadout hole (6); protective seam (7) forms; groove (2) is carved with in the inside surface boring of housing (1); be fixed with successively heat-barrier material (3) and insulating material (4) on groove (2) surface; special coil (5) is embedded in the outside of insulating material (4), the upper also dressing non-metal insulating material protective seam (7) in its surface.
Enforcement recited above is only that the preferred embodiment of the present invention is described; be not that the spirit and scope of the present invention are limited; under the prerequisite that does not break away from design concept of the present invention; various modification and improvement that in this area, common engineering technical personnel make technical scheme of the present invention; all should fall into protection scope of the present invention; the technology contents that the present invention asks for protection all is documented in claims
