Abstract
The utility model relates to a drift well gauge tool applied for oil-gas field underground steel wire operation well drifting, mainly comprising a connection head, a connection pipe and a scraping body, wherein the connection head is cylindrical and a raised annular step is arranged on the connection head. The cylindrical connection pipe is connected with a lower end of the connection head and a center hole is arranged on the connection pipe. An axial flowing channel is arranged on the connection pipe wall. A cylindrical scraping body is connected with the lower end of the connection pipe, symmetric inclined surfaces with inclined degree of 30-60 degree are arranged on the lower part of the scraping body, a guide head is arranged on the lower end of the scraping body and two end of two inclined surfaces and two inclined surfaces are symmetrically distributed at the outer side of the guide head. The effect of the drift well gauge tool is that: in case of having the function of the conventional drift well gauge tool, the drift well gauge tool smoothly passes the relative large step in the well shaft, therefore the working success ratio is ensured and the working risk is reduced.
Description
Technical field
The utility model relates to the oil-gas field downhole operation technical field, and the special tool of particularly a kind of down-hole steel wire operation is a kind of drift size gauge tool.
Background technology
Steel wire operation is an operation that often relates in the oil gas field manufacturing process, and it is simple to have equipment.Low price, in light weight, simple to operate, be easy to go into the well and characteristics such as applied widely, be commonly used to finish work such as pressure and temp test, production logging, spy sand face, paraffin cutting, pulling blanking plug, switching sliding sleeve, oil pipe punching.Drift size gauge tool is the instrument that steel wire operation is gone into the well for first, its mainly act on be the cleaning borehole wall and the guaranteeing instrument that will be lowered to and instrument can be smoothly down to the position of expection.
Chinese patent notification number: CN201121497 provides " a kind of multi-functional drift size gauge tool ".Comprise the drift size gauge tool main body, in the bottom of drift size gauge tool main body sawtooth is set, wherein, the inwall of 10～30 centimetres drift size gauge tool main body is provided with the barb of a plurality of triangles in the distance bottom, and barb slopes inwardly.Effect: by bottom hard sawtooth is set at existing drift size gauge tool, cover mill the sand washing construction convenient, not only save time but also increase work efficiency.When the drifting tubing string is met card, can anti-circulation well cleanup, be convenient to accident treatment.
At present, steel wire operation drift size gauge tool bottom side is considered as plane structure, and there is chamfering its inside, can realize the function of cleaning tube wall, can't pass through but run into the bigger step that undergauge produced, thereby influence next step operation because its plane structure causes in the bigger directional well of hole deviation.
The utility model content
The purpose of this utility model is: a kind of drift size gauge tool is provided, and having cleaning borehole wall function again can be by step in the bigger well.
The technical solution adopted in the utility model is: drift size gauge tool, mainly form by connector, tube connector and scraping body, connector is the cylinder bodily form, the raised annular step is arranged on connector, connector is that screw thread also can snap joint, be used for connecing, with the drift size gauge tool G.I.H with standard steel wire power tool polyphone.It is characterized in that: be connected with cylinder bodily form tube connector in the lower end of connector, tube connector has centre bore; Connecting the circulation passage that has on the tube wall vertically, circulation passage can guarantee that the impurity that the borehole fluid and the cleaning borehole wall produce passes through from drift size gauge tool inside smoothly.Be connected with cylindrical shape scraping body in the lower end of tube connector, the gradient of symmetry is arranged at the bottom of scraping body is the inclined-plane of 30～60 degree, in the lower end of scraping body and in the lower end on two inclined-planes target seeker is arranged, and is symmetrically distributed with two inclined-planes in the outside of target seeker.Target seeker can be smoothly by the step less than the drift size gauge tool radius, and the body of scraping simultaneously has skiving blade, can clean tube wall.
The gradient on two inclined-planes that the described target seeker outside is symmetrically distributed is between 30～60 degree.
The beneficial effects of the utility model: the utility model drift size gauge tool, possess the situation of original drift size gauge tool function, can be smoothly by big step in the pit shaft, thereby guaranteed operation success rate, reduce operating risk.Have that processing is simple, operation convenient, expense reaches the little advantage of risk less.
Description of drawings
Fig. 1 is the utility model drift size gauge tool structural profile schematic diagram.
Fig. 2 is the A-A generalized section of Fig. 1.
Fig. 3 is the partial left pseudosection of Fig. 1.
Among the figure, 1-connector, 2-tube connector, 3-circulation passage, 4-scraping body, 5-inclined-plane, 6-target seeker.
The specific embodiment
Embodiment 1: with a multi-functional drift size gauge tool is example, and the utility model is described in further detail.
The utility model drift size gauge tool is used to solve conventional drift size gauge tool can't be by big step problem in the pit shaft.
Consult Fig. 1.Drift size gauge tool mainly is made up of connector 1, tube connector 2 and scraping body 4.Connector 1 is the cylinder bodily form, and the raised annular step is arranged on connector 1, and can adopt is screwed connection.Be connected with cylinder bodily form tube connector 2 in the lower end of connector 1, it is 40 millimeters centre bore that tube connector 2 has diameter.It is 20 millimeters that two width are vertically arranged on tube connector 2 walls, and length is 60 millimeters circulation passage 3.Be connected with external diameter in the lower end of tube connector 2 and be 50 millimeters cylindrical shape scraping body 4, the gradient of symmetry is arranged at the bottom of scraping body 4 is the inclined-planes 5 of 45 degree.In the lower end of scraping body 4 and in the lower end on two inclined-planes 5 target seeker 6 is arranged, be symmetrically distributed with the inclined-plane of two 45 degree in the outside of target seeker 6.The thickness of target seeker 6 is 8 millimeters.
