Abstract
This utility model relates to an oil tube drift diameter gauge for inspecting the oil tube inner diameter before the oil field workover operations, consisting of a little entity 1, fixed entities 2, 4 and a joint lever 3; wherein, the two upper and lower fixed entities 4, 2 with the same specifications are connected through the joint lever 3, and the front end of the lower fixed entity 2 is connected to the little entity 1 of a thinner diameter by screw thread. The oil tube drift diameter gauge has advantages of simple structure, easy preparation and convenience for using. By using it, workers can smoothly complete the paraffin removal on the oil tube inner wall and checking-up of the oil tube curving degree, ensuring a smooth workover operation. The instrument can be used time and again for a plurality of times under the conditions of conforming the working standards, thus saving the cost of workover operations.
Description
Technical field:
The utility model relates to a kind of preceding oil pipe latus rectum checking tool of oil well repairing operation construction that is used for.
Background technology:
Tube inner wall wax removal, the inspection of tubing bending degree are the important preliminary work before the oil well repairing operation construction, and very important to guaranteeing the workover rig service to oil well quality, the comparatively serious old oil pipe of long period or wax deposition is all the more so for using.At present, the oil pipe drift diameter gauge that is adopted when oil pipe wax removal latus rectum inspection work is carried out at the scene is an identical permanent entity of two diameter up and down, the middle employing is connected by the less connecting link of diameter, by the permanent entity part tube inner wall carried out wax removal or oil pipe is carried out the degree of crook inspection.When carrying out above work, carry on the hook that the oil pipe lower end progressively erects in the oil pipe process on slideway, the oil pipe drift diameter gauge of putting into oil pipe owing to the inertia reason drops on the slideway rapidly with big inertial force, and clash into it, make drift diameter gauge permanent entity diameter become big, can't continue in the testing afterwards to use.For this reason, the frequent drift diameter gauge that meets construction reference of changing of having to causes the goods and materials waste, and cost increases.
Summary of the invention:
The utility model purpose is to provide a kind of oil pipe drift diameter gauge that not only can guarantee construction reference but also can repeatedly use repeatedly.
The utility model is to realize like this.This kind oil pipe drift diameter gauge is made up of little entity, permanent entity and connecting link; promptly set up the thinner little entity of a diameter at existing oil pipe drift diameter gauge bottom permanent entity front end; make when the oil pipe latus rectum detects the little entity by this drift diameter gauge front end at first contact with slideway; thereby protect its permanent entity diameter to remain unchanged; meet construction reference; can prolong simultaneously drift diameter gauge serviceable life, save and produce this.This kind oil pipe drift diameter gauge principle of work is as follows: under the workover rig service to oil well before the oil pipe, this oil pipe drift diameter gauge is put into oil pipe inside, then by the hook oil pipe of slinging, after oil pipe is vertically sling, the little entity of the oil pipe drift diameter gauge in the oil pipe is at first fallen above the slideway, and permanent entity just drops on the slideway then.Finish the inspection of inner wax removal of oil pipe and tubing bending degree successively according to above-mentioned method, the oil pipe after the inspection is gone into the well by screwed connection.
The utility model is simple in structure, is easy to make, and is easy to use, utilizes it can finish tube inner wall wax removal and tubing bending degree inspection work smoothly, guarantees that workover operation construction carries out smoothly.This instrument is saved the cost of workover treatment guaranteeing to meet under the situation of construction reference and can repeatedly using repeatedly.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
The utility model is provided by following examples.
Below in conjunction with accompanying drawing the utility model is described further.
As shown in the figure, the utility model is made up of little entity 1, permanent entity 2,4 and connecting link 3, its structure, assembled relation are as follows: be connected by connecting link 3 between the identical permanent entity 4,2 of upper and lower two specifications, following permanent entity 2 front ends are hinged with the thinner little entity 1 of a diameter by screw thread.Wherein, upper and lower two permanent entities 4,2 and connecting link therebetween 3 are made as one, two permanent entity external diameters and standard oil bore match, promptly there is not wax deposition or oil pipe does not have under the crooked situation at tube inner wall, drift diameter gauge can pass through in oil pipe smoothly, and following permanent entity 2 is provided with to be connected with little entity 1 uses internal thread.Connecting link 3 diameters are slightly little.Little entity 1 is a filled circles body of rod, and the one end is provided with to be connected with following permanent entity 2 internal threads uses external thread.
