Abstract
The utility model relates to a continuous oil pipe vibration reinforcing device which belongs to continuous oil pipe downwell tools. In operation, the upper part of the continuous oil pipe vibration reinforcing device is connected with a weight increasing rod, and the lower part is connected with a vibrating device for vibration operation. A long mandrel, a short mandrel and a piston extending shaft are successively connected through a screw thread for forming a mandrel assembly. An oil injection nipple, a mandrel outer cylinder, a piston outer cylinder and a lower joint are successively connected through a screw thread for forming an outer cylinder assembly. Dynamic connection is formed between the mandrel assembly and the outer cylinder assembly through a dynamic sealing assembly. The chambers of the mandrel assembly and the outer cylinder are filled by liquid. The dynamic connection and the liquid form a closed liquid cylinder. A balancing piston and the closed liquid cylinder form a hydraulic spring. Because the hydraulic spring has characteristics of energy storage and releasing delay, delaying and reinforcing functions are performed on vibration of the vibrating device.
Description
Technical field
The present invention relates to petroleum machinery downhole tool field, particularly a kind of and weighted lever and bumper jar are used coiled tubing jarring booster.
Background technology
The coiled tubing first Application is during World War II, and 1962 really are applied to petroleum industry.The 60-70 age is in the exploratory stage, and the eighties is along with the raising of steel material and the significant innovation of coiled tubing manufacturing process, and the improving constantly of coiled tubing equipment availability performance, and makes the coiled tubing service behaviour fundamentally be improved.Now, the coiled tubing technology is promoted the use of in a plurality of fields of oil exploration abroad.And domestic coiled tubing operation development is late, and is low with respect to external level of operation.And one of principal element that this technology of restriction coiled tubing is applied in China is the development of underground work instrument.The present utility model belongs to a kind of of coiled tubing downhole tool, is mainly used in the jarring operation in drilling well or the well workover.
Summary of the invention
The present invention is that the jarring that a kind of and coiled tubing bumper jar connect use strengthens instrument.In operation process, when operation in the well was met stifled or met card, its top linked to each other with weighted lever by axle, and the bottom links to each other with bumper jar by lower contact, and supporting bumper jar carries out jarring de-plugging or unfreezing.The liquid spring that itself is made up of a plurality of complicated parts is because storage power and the release delay of liquid spring play time-delay and humidification to the jarring operation.
The main component content of this instrument is as follows:
Grow axle (1) and lack axle (7), piston outrigger shaft (10) successively by being threaded into the axle one; Oiling pipe nipple (2), axle urceolus (4), piston urceolus (6) and lower contact (11) also connect into the urceolus one by screw thread successively; Between axle one and urceolus one, be dynamically connected by dynamic sealing assembly formation, be full of liquid in the cavity of the two, form airtight fluid cylinder.The inside and outside wall of dummy piston (8) respectively has one group of movable sealing that its pressure at two ends is sealed, and dummy piston (8) and airtight fluid cylinder have formed hydraulic spring grease cup.
Description of drawings
Fig. 1 is the structure chart of coiled tubing jarring booster and since structure elongated be difficult to show with a width of cloth figure clear, so separately demonstration among Fig. 1.
Fig. 2 is the contract drawing of the structure chart of coiled tubing jarring booster.
Among the figure, 1-long axle; 2-oiling pipe nipple; 3-oil filler plug; 4-axle urceolus; 5-sealing semi-ring; 6-piston urceolus; 7-short axle; 8-dummy piston; 9-dynamic sealing assembly; 10-piston outrigger shaft; 11-lower contact.
The specific embodiment
When transmit downward pressure from weighted lever, the axle one is stressed downwards, and liquid promotes dummy piston (8) and also moves downward, and along with the downward passing of dummy piston (8), dummy piston (8) lower liquid pressure increases storage power gradually.When the fluid pressure of dummy piston (8) bottom greatly to overcoming various dynamic sealing assemblies (9) and sealing the frictional resistance of semi-ring (5), the liquid promotion lower contact (11) of dummy piston (8) bottom, piston urceolus (6), axle urceolus (4) move downward, because lower contact is connected with the top connection of bumper jar, thereby promote the downward jarring of bumper jar.Hydraulic spring grease cup is out of shape storage power by push-and-pull, because the retardation characteristics the when energy storage of liquid and release, it is operated by direct push-and-pull, energy-storage function plays the amplification enhancing to the downforce of weighted lever transmission, by acceleration being provided for weighted lever and providing free travel for bumper jar top, the spring strain is removed when the bumper jar free stroke, and energy stored also will be released, and weighted lever and bumper jar could accelerate when being subjected to strong jarring.Its retardation characteristics can not pass on the bumper jar downforce of weighted lever immediately, are a kind of good protections to the bumper jar in the operation.
Otherwise when preparing upwards to carry out the jarring operation, all are stressed, motion is with above-mentioned opposite, drive the bumper jar jarring that makes progress at last.Its jarring enhancing and delay function are same as described above.
The present invention's design is in the demand of analyzing bumper jar operation real process, carries out appropriate design targetedly, satisfies user demand.
