Description
Technical Field
The invention relates to the field of oil and gas field operation equipment, in particular to an oil pipe scaling detection tool.
Background
In the production process of a gas well, oil gas conveyed by a pipeline contains mixed media such as organic matters, hydrogen sulfide, carbon dioxide and the like, and under the common influence of well temperature and well pressure, the media can scale on the inner wall of an oil pipe, so that the inner diameter of the oil pipe is reduced, and the safety of test operation is seriously endangered. Therefore, it is necessary to develop an oil pipe scale detection tool to facilitate the detection of oil pipe scale and the subsequent research of scale removal and prevention. For example, chinese patent No. CN 103967475 a, published as 20140806, discloses an oil pipe scale formation detection tool, wherein an elliptical elastic ring in a compressed state is mounted on a tool main body, a half shaft of the elastic ring in a longitudinal direction is compressed by positioning pins to form a short half shaft, a long half shaft in a transverse direction is the maximum outer diameter of the detection tool, and a plurality of positioning pins are arranged on the tool according to the size of the long half shaft of the elastic ring, i.e., the outer diameter of the tool. When the detection tool is used, the tool is placed into an oil pipe through a well testing winch, the position is recorded when the detection tool is blocked, the shear blade on the elastic ring can cut off the positioning pin on the tool body under the combined action of the elasticity of the elastic ring and the vibrator arranged at the other end of the detection tool, the long half shaft of the elastic ring is reduced, the short half shaft of the elastic ring is increased, the detection tool continues to detect downwards, and the scaling condition in the oil pipe can be obtained according to the change of the position of the blocking. However, due to the complicated shape of the scale in the oil pipe, different deformation amounts are generated on both sides of the elastic ring, and the maximum outer diameter of the tool is not the maximum outer diameter of the tool when the pin is preset, and the detection result obtained by shearing the locating pin is inaccurate.
Disclosure of Invention
The invention aims to provide an oil pipe scaling detection tool to solve the problem that the detection result of the existing detection tool is inaccurate.
The technical scheme of the invention is as follows: the utility model provides an oil pipe scale deposit detecting tool, includes body, dowel, is equipped with the cavity on the body, runs through the cavity interval and is provided with at least one dowel, still includes two shear slices, the shear slice articulate and constitute shear type structure on the body, shear type structure's outside protrusion body.
The shearing sheet is provided with a concave arc-shaped shearing edge.
The articulated end of the shearing sheet is provided with an articulated hole, and the edge of the shearing sheet deviating from the shearing edge is provided with a round angle at the end far away from the articulated end.
The shearing sheet is hinged on the position of the body close to the upper part of the cavity.
The invention has the beneficial effects that: the utility model provides an oil pipe scale deposit detecting means, adopts the scissors structure shearing dowel that two shear sections constitute, and the shape of shear section is fixed, can not warp and influence the detection result.

Detailed Description
The following further describes embodiments of the present invention with reference to the drawings.
A specific embodiment 1 of the oil pipe scale detection tool of the present invention is shown in fig. 1 to 2: the oil pipe scale formation detection tool comprises a body 1 and positioning pins 2, wherein the upper portion of the body is provided with a mounting screw hole 11 used for being connected with a vibration device, the lower portion of the body is provided with a conical guide head 12, a cavity 13 is formed in the body, 4 positioning pins 2 are arranged at intervals of penetrating through the cavity respectively, the oil pipe scale formation detection tool further comprises a shear type mechanism formed by two shear sheets 31 and 32, and the outer side of the shear type mechanism protrudes out of the body. The hinged end of the shearing sheets 31 and 32 is provided with a hinged hole, the other end of the shearing sheets is provided with a round angle, the guiding is convenient, the shearing edges of the shearing sheets are in a concave arc shape, and the two shearing sheets are hinged on the position, close to the upper part of the cavity, of the body through a hinged pin 4. When the two shearing sheets are in different opening and closing positions, the detection tool has different maximum outer diameters, and then a positioning pin 2 is arranged at a position corresponding to the corresponding outer diameter. When the two shear blades sequentially shear the pin, the maximum outer diameter of the tool is gradually reduced.
When the oil pipe scaling detection tool is used for detection, a well testing winch is used for descending the oil pipe scaling detector into a well, if the tool is blocked, the blocking position is recorded, at the moment, two shearing sheets are firstly sheared by the scaling of the oil pipe in the well, the shearing sheets are vibrated by a vibrator to shear the positioning pin, so that the opening of a shearing mechanism is reduced, the outer diameter of the tool is reduced, and then downward detection is continued. Therefore, the scaling condition of the oil pipe in the well can be accurately known through the change of resistance positions for several times, and then the later-stage scale prevention and removal research is carried out.
In embodiment 2 of the oil pipe fouling detection tool of the present invention, as shown in fig. 3, the shearing edges of the shearing blades 231, 232 are straight edges, and the shearing blades shear the dowel pin from top to bottom.
In example 1 of the oil pipe scale detection tool of the present invention, the shear blade has a concave arc-shaped shear edge. In other embodiments of the oil pipe scale detection tool of the present invention, the shearing edge of the shearing sheet may be an inwardly concave dogleg-shaped shearing edge.
In embodiments 1 and 2 of the oil pipe fouling detection tool of the present invention, the edges of the shear blades facing away from the shear edge are provided with rounded corners. In other embodiments of the oil pipe fouling detection tool of the present invention, the fillet may also be a bevel.
In embodiments 1 and 2 of the oil pipe scale detection tool of the present invention, two shear blades are hinged to the body by a hinge pin to form a scissor mechanism. In other embodiments of the oil pipe fouling detection tool of the present invention, the two shear blades may be hinged to the body by two hinge pins, respectively.
In embodiments 1 and 2 of the oil pipe scale detection tool of the present invention, the shear blade is hinged to the body at a position near the upper portion of the cavity. In other embodiments of the oil pipe scale detection tool of the present invention, the shear blade may also be hinged to the body near the lower portion of the cavity.
