Abstract
A special reamer for a coiled tubing relates to the field of coiled tubing operation in the oil field and comprises a connecting rod, wherein the upper end of the connecting rod is sleeved with a gravity hammer; the lower end of the connecting rod is connected with a picking knife made of high-speed tool steel; and the lower end of the connecting rod, which is connected with the picking knife, is in replaceable connection with a reamer made of hard alloy steel. According to the internal diameter of the coiled tubing, the special reamer for picking and reaming is made of high-speed tool steel and hard alloy material; and when the special reamer is in use, the high-speed tool steel is used for picking welding seams in the coiled tubing at first, and then the hard alloy reamer is used for precise reaming, so that the field work intensity is reduced and the reaming precision of the inner wall of the coiled tubing and the leak tightness of the coiled tubing and the connector are both improved.
Description
Technical field
The utility model relates to coiled tubing operation field, oil field.
Background technology
The coiled tubing implement is in the oil field formation testing, test, well workover, aspects such as operation are extensive use of, the oil pipe that uses also length thickness has nothing in common with each other, but all oil pipes all are to connect with the pressure welding of low-carbon alloy roll of steel plate to form, there is a weld seam all the time in tube inner wall, when the oil pipe female connector is installed, must remove oil pipe end 100mm clean with interior weld seam, and reach the certain precision requirement, otherwise influence the sealing between oil pipe and the connector easily, traditional oil pipe reamer is to make with medium carbon steel, cutting power is poor, make troubles to execute-in-place, the precision after the processing is low, suppresses job execution in the oil pipe circulation and brings potential safety hazard.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of coiled tubing special reamer to be provided, and cutting power is strong, and execute-in-place is convenient, the oil pipe precision height after the processing.
The purpose of this utility model is achieved in that the coiled tubing special reamer, comprise connecting rod, the upper end of connecting rod is nested with gravity drop hammer, the lower end of connecting rod connects by what high-speed tool steel was made picks sharpener, picks the reamer that the replaceable connection in lower end of the connecting rod of sharpener is made by hard alloy steel in connection.
Operating principle of the present utility model: during use gravity drop hammer is enclosed within on the connecting rod, to pick the instrument of cutting is connected on the connecting rod, by on hit gravity drop hammer and reject weld seam in the oil pipe, connect carbide-tipped reamer again, rotation ream limit, limit is with hitting reamer on the gravity drop hammer to the ream position.
According to pipe aperture, select for use high-speed tool steel and Hardmetal materials to make to pick and cut and the ream special reamer, first with the weld seam in the high-speed tool steel rejecting oil pipe during use, carry out accurate ream with carbide-tipped reamer again, namely reduce site work intensity, improved the ream precision of tube inner wall and the sealing of oil pipe and connector.
