Abstract
The utility model relates to an oil pipe connection protector for oil fields, and belongs to the field of petroleum equipment. The protector takes the shape of a pipe hoop; internal threads are formed at the thick opening end and the thin opening end of the protector; the difference between the inner diameters of the thick and the thin opening ends corresponds to the thickness of the inner liner of an oil pipe; and the inner surface of the protector is a smooth inclined surface. When the oil pipe connection protector is in use, a common oil pipe with no inner liner is in threaded connection with the thick opening end of the protector; and the oil pipe with the inner liner is in threaded connection with the thin opening end of the protector. The oil pipe connection protector has the benefits of simple structure, convenience in use and high practicability; and the phenomenon that when the common oil pipe with no inner liner and the oil pipe with the inner liner are connected during the use, a pumping rod collar clamps, tows and drags the oil pipe with the inner liner rigidly can be prevented effectively, so that the service life of the oil pipe with the inner liner is prolonged.
Description
Technical field
The utility model relates to the oil equipment field, and particularly a kind of oil field connects protector with oil pipe.
Background technology
Produce in the oil well of crude oil in petroleum industry, the ratio of inclined shaft accounts for 30% of whole oil wells, and in recent years quantity increase gradually, widely distributed.The tube inner wall eccentric wear is very serious, and some oil well some months will produce serious oil pipe mill and leak phenomenon, directly influences crude oil yield.Annual therefore cause directly, nearly 10,000,000,000 yuan of indirect loss, make the people startling.People from oil field be for addressing this problem a large amount of measures of having taked, as the compound lining oil pipe that adopts glass-lined, ceramic-lined, anticorrosion antiwear etc.But, when common no liner oil pipe is connected use with the oil pipe that has liner, the rigid card of beam hanger box cupling can occurs, drag, drag the phenomenon that has the liner oil pipe, cause having the oil pipe end breakage of liner, whole oil pipe can't use when serious, need stop well servicing, influences ordinary production.
Summary of the invention
The purpose of this utility model is to provide a kind of oil field to connect protector with oil pipe, has solved the liner oil pipe when reality is used, and easily causes having the oil pipe end breakage of liner, and whole oil pipe can't use when serious, need stop well servicing, influences problems such as ordinary production.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions:
The oil field connects protector with oil pipe, and protector is the pipe collar shape, and thick mouthful of end 1 is respectively equipped with internal thread with thin mouthful of end 2, and this thick mouthful of end 1 is corresponding with the thickness of thin mouthful of difference of holding 2 internal diameter and oil pipe liner, and the inner surface of protector is a smooth bevel.During use, common no liner oil pipe is threaded with thick mouthful of end 1 of protector, and the oil pipe that has liner is threaded with thin mouthful of end 2 of protector.
The beneficial effects of the utility model are: simple in structure, easy to use, effectively protect oil pipe, and increase oil pipe application life, practical.
Description of drawings
Fig. 1 is a structure cross-sectional schematic of the present utility model.
The specific embodiment
Further specify the detailed content of the present utility model and the specific embodiment thereof below in conjunction with accompanying drawing.
Referring to Fig. 1; oil field of the present utility model connects protector with oil pipe, and protector is the pipe collar shape, and thick mouthful of end 1 is respectively equipped with internal thread with thin mouthful of end 2; should thick mouthful end 1 corresponding with the thickness of thin mouthful of difference of holding 2 internal diameter and oil pipe liner, the inner surface of protector is a smooth bevel.During use, common no liner oil pipe is threaded with thick mouthful of end 1 of protector, and the oil pipe that has liner is threaded with thin mouthful of end 2 of protector.
Claims (1)
1. an oil field connects protector with oil pipe; it is characterized in that: protector is the pipe collar shape; thick mouthful of end (1) is respectively equipped with internal thread with thin mouthful of end (2), and the difference of this thick mouthful of end (1) and the thin mouthful of internal diameter of holding (2) and the thickness of oil pipe liner are corresponding, and the inner surface of protector is a smooth bevel.
