Abstract
The utility model relates to an eccentric water injection tool for a highly deviated well and belongs to an underground water injection tool for separate layer water injection of a water injection well of an oil field. The eccentric water injection tool for the highly deviated well is suitable for carrying out construction operation, dropping and fishing test and separate layer water injection on the highly deviated water injection well of the oil field. An upper joint is in threaded connection with an upper connecting sleeve and is sealed by an O-shaped ring; the upper connecting sleeve is in threaded connection with a working barrel and is sealed by an O-shaped ring; the working barrel is in threaded connection with a lower connecting sleeve and is sealed by an O-shaped ring; the lower connecting sleeve is in threaded connection with a lower joint and is sealed by an O-shaped ring; a righting body is positioned in the upper connecting sleeve and is connected with the working barrel by a bolt; a bracket is positioned in the lower connecting sleeve; a step of the bracket is sleeved on a step of the working barrel and is fixed by a screw; a guiding body is positioned in the bracket and is connected with the bracket by a bolt; and a blanking plug is positioned in a deflection hole of the working barrel. The eccentric water injection tool has a reasonable structure and is suitable for carrying out construction operation and dropping and fishing test in the highly deviated well.
Description
Affiliated technical field
The utility model relates to a kind of underground water-injection instrument that is used for the water injection well in oil fields seperated layer water injection, especially is applicable to the eccentric water filling instrument of high angle hole seperated layer water injection.
Background technology
In oilfield development process, water filling plays an important role to the raising of Oilfield developing and recovery ratio, recover the oil and the balance of the water filling enforcement direction that will in a very long time, become to attach most importance to, along with continually developing of oil field, improving constantly of drilling technology, oil field big gradient well quantity is increasing year by year, the pulling success rate in high angle hole of eccentric injection mandrel in the past is low, can not satisfy the demand for development of oil-field flooding technology, so a kind of water filling instrument that is used for the high angle hole seperated layer water injection is badly in need of in the oil field.Existing hollow distributor, with one heart the intrinsic feature limits of injection well downhole flow regulator the progression of dispensing, pulling is also inconvenient.
Summary of the invention
In order to solve the deficiency of existing water filling instrument, satisfy the waterflooding requirement of oil field high angle hole, the utility model provides a kind of big inclined shaft eccentric water filling instrument.The utility model is rational in infrastructure, is applicable to construction operation in high angle hole, dropping-fishing test.
The technical scheme that its technical problem that solves the utility model adopts is: high angle hole eccentric center water-distributing instrument, top connection is threaded with upper joint sleeve, and pass through seal with O ring, upper joint sleeve is threaded with seating nipple, and pass through seal with O ring, seating nipple is threaded with lower joint sleeve, and by seal with O ring, lower joint sleeve is threaded with lower contact, and pass through seal with O ring, centralizer body is positioned at upper joint sleeve, links to each other with seating nipple by bolt, and support is positioned at lower joint sleeve, the step of support is enclosed within on the step of seating nipple and passes through screw, guide way is positioned at support, links to each other with support by bolt, and blanking plug is positioned at the inclined to one side hole of seating nipple.Centralizer body is provided with the opening righting trough, guide way is provided with guide track and open slot, the guide track upper end is a cusped edge, the lower end links to each other with open slot, seating nipple is provided with inclined to one side hole and water filling port, and support is provided with spout, and the inner oil tube screw thread is arranged at top connection top, outer tubing round thread is arranged at the lower contact bottom, is connected with oil pipe when being used to go into the well.
During use, earlier with the eccentric water filling instrument of big inclined shaft down to the downhole designs position, after suppressing the dispensing packer that makes on the water injection string and enter duty by ground, go into the well with special-purpose throw in catcher and to drag for blanking plug, special-purpose throw in catcher is after guide track on the guide way and open slot guiding, catch blanking plug and blanking plug pulled out, blanking plug dead stifled is replaced by water nozzle after, blanking plug is had high input in the inclined to one side hole of the eccentric water filling tool work of inclined shaft tube by special-purpose throw in catcher again.At this moment, can carry out water filling to purpose water filling layer.
The beneficial effects of the utility model are, provide a kind of can be in the high angle hole of oil field construction operation, dropping-fishing test, the eccentric water filling instrument of big inclined shaft that carries out seperated layer water injection.
