Abstract
The utility model provides a flexible short circuit of oil pipe, characterized by inner tube (3) one end is connected coupling (1), installs rubber ring (4) on the other end outer wall, and its outside of tubes still overlaps and is equipped with outer tube (2), and outer tube (2) one end attach fitting (5), and rubber ring (4) are also installed to the other end. The utility model has the advantages of being simple in structure and convenient in operation, reliable operation for in-process such as oil field sand washing, well-flushing is installed in the tap lower extreme, and axial and radial relative movement are realized to accessible inner tube (3) and outer tube (2), thereby have reduced the oil pipe column and have added single construction degree of difficulty.
Description
Technical field: the utility model relates to a kind of oil field and uses downhole tool, especially for the flexible short circuit of a kind of oil pipe of underground work.
Background technology: before the utility model, the single modes that add that adopt owing to the first-class load of the fire hose is bigger, have increased difficulty to adding single construction more when deepening tubing string in the underground work processes such as each Sand-washing in Oilfield, well-flushing.
Summary of the invention: the purpose of the utility model is: for oilfield downhole operation provides a kind of oil pipe short circuit that stretches; Can be installed on the water tap lower end; Because this device can be realized axially and relatively moving radially through interior pipe and outer tube, add single difficulty of construction thereby reduced tubing string.
The purpose of the utility model realizes through following measure: a kind of oil pipe short circuit that stretches; Be to constitute by box cupling, interior pipe, outer tube, cushion rubber, joint; It is characterized in that the interior Guan Yiduan of elongate tubular is connected with the box cupling of tubing thread, be processed with seal groove on the other end outer wall and cushion rubber is installed, the outer outer tube that also is set with elongate tubular of its pipe; Outer tube one end is connected with the joint of tubing thread, is processed with seal groove on the other end inwall and cushion rubber is installed.
The utility model is simple in structure, easy to operate, reliable operation, is used for processes such as Sand-washing in Oilfield, well-flushing and is installed on the water tap lower end, can realize axially and relatively moving radially through interior pipe and outer tube, adds single difficulty of construction thereby reduced tubing string.
Description of drawings: Fig. 1 is the structural representation of the flexible short circuit of oil pipe.
The specific embodiment: the flexible short circuit of oil pipe is to be made up of box cupling 1, interior pipe 3, outer tube 2, cushion rubber 4, joint 5; Interior pipe 3 one ends of elongate tubular are connected with the box cupling 1 of tubing thread; Be processed with seal groove on the other end outer wall and cushion rubber 4 is installed; The outer outer tube 2 that also is set with elongate tubular of its pipe, outer tube 2 one ends are connected with the joint 5 of tubing thread, be processed with seal groove on the other end inwall and cushion rubber 4 is installed.
The operating principle and the method for using of the flexible short circuit of oil pipe are: through box cupling 1 this device is installed on the water tap lower end earlier, it is single to connect oil pipe through joint 5 again, just can it be mentioned with the downhole oil tubing string to be connected; Because pipe 3 and outer tube 2 can relatively move vertically or radially in connection procedure, can be adjusted to best link position with oil pipe is single, thereby reduce the difficulty of construction that is connected with the downhole oil tubing string; Also because interior pipe 3 has long flexible distance with outer tube 2, can extend adds single construction depth at every turn, thereby has improved the efficiency of construction of underground work.
