Abstract
The invention relates to a sensor capable of measuring the diameter of a discrete type steel pipe dynamically and statically in a non-contact mode. The sensor comprises a shell body (1), a groove (2), thermal insulation materials (3), insulating materials (4), a special coil (5), a signal line guide-out hole (6) and a protection layer (7). When a steel pipe to be measured dynamically passes through or is statically placed on a central position of the sensor, a sole electrical parameter corresponding to the diameter of the steel pipe is to appear, and thus a conversion function of a steel pipe diameter parameter and the electrical parameter is achieved.
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
