Abstract
The utility model relates to a high-efficiency wire-line workover unit used for carrying out job execution for technology service wells for steaming operation, fracturing, etc., which is composed of a main body (1), 2 (1/2), a short joint (2) and a coupling (3). The utility model has the advantages of simple structure, convenience and practicability, two construction tasks of cleaning bur and dirt for the bushings for oil wells and sand surface exploration can be completed smoothly with high efficiency nothing remains but to disassemble a pipe column once, the construction efficiency is increased and the labor intensity of workers is lightened.
Description
Technical field:
The utility model relates to a kind of downhole tool that technological measure wells such as vapour, pressure break carry out job execution that is used to annotate.
Background technology:
Annotate technological measure wells such as vapour, pressure break when carrying out job execution, must carry out the casing inner diameter drifting earlier and visit sand face twice important procedure.Whether at present, on-the-spot common way was lowered to drift size gauge tool before this oil well casing was carried out drifting, remove the burr on the Jing Neitaoguanbi and implement sleeve pipe intact, also will trip out former tubing string then and be lowered to light pipe and visit the sand face.Like this, need remove tubing string twice, not only increase the labour intensity of operating worker, and spended time is long, operating efficiency is low, and the construction cost height influences the raising of oil well ordinary production and economic benefit.
Summary of the invention:
The purpose of this utility model is to provide a kind of can simplify service shaft job execution operation, save the efficient drift size gauge tool of a large amount of human and material resources, financial resources.
The utility model is to realize like this." box cupling is connected with 2 with body with screw thread respectively for this kind drift size gauge tool is by drift size gauge tool body, 2 " pipe nipple and box cupling are formed, and one 2 are set in the drift size gauge tool body " pipe nipple, pipe nipple upper and lower end.During use, drift size gauge tool body upper end is connected with corresponding tubing string, 2 " connect the tail pipe of respective length under the box cupling.During construction operation, along with the intensification of underground work tubing string, this drift size gauge tool body part carries out scraping to the oil well casing wall, removes the foul in burr and the sleeve pipe, and implements sleeve pipe and whether meet standard-required.Needn't rise under the lower tubular column situation, with this drift size gauge tool with down connect the tail pipe co-operation and arrive sand face or artificial bottom of a well at last, can further finish the construction task of spy sand face.
The utility model is simple in structure, practical and convenient, adopt this drift size gauge tool only to need one trip can finish the clear burr of oil well casing, dirt drifting and two construction tasks of spy sand face smoothly, efficiently, improve efficiency of construction greatly, alleviate labor strength, save a large amount of operating costs, be suitable for and apply.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
As shown in the figure, " box cupling 3 is connected with 2 with body 1 with screw thread respectively for the utility model is by body 1,2 " pipe nipple 2 and box cupling 3 are formed, and its assembled relation is as follows: one 2 are set in the body 1 " pipe nipple 2, pipe nipple 2 upper and lower ends.Wherein, body 1 is the up-small and down-big hollow round tube body of diameter, and its material specification is identical with normally used drift size gauge tool.2 " pipe nipple 2 and box cupling 3 can adopt 2 respectively " tubing nipple and box cupling.
Claims (1)
1, a kind of efficient drift size gauge tool is by body (1), 2 " pipe nipple (2) and box cupling (3) are formed, and it is characterized in that: body is provided with one 2 in (1) " pipe nipple (2), " box cupling (3) is connected pipe nipple (2) upper and lower end with body (1) and 2 with screw thread respectively.
