摘要： An apparatus includes a scale removal head, a scale collector, a circulating plate assembly, and a guide. The scale removal head includes a plurality of blades that scrape against a wall of a wellbore to remove scale from the wall of the wellbore in response to rotation of the apparatus. The scale collector defines a first inner region within a surrounding slotted chamber. The circulating plate assembly defines a second inner region within a pipe. The first inner region and the second inner region together define a collection volume for accumulating and storing scale that has been removed from the wall of the wellbore. The guide includes a plurality of blades that scrape against the wall of the wellbore to remove scale from the wall of the wellbore as the apparatus rotates.

摘要： An integral permanent bridge plug assembly for a wellbore. The integral permanent bridge plug assembly includes a permanent bridge plug mounted to a cylindrical body, a setting sleeve, a bottom connection, an engagement assembly mounted to an outer diameter of the cylindrical body that is selectively extendible between a recessed position and an extended position, and a scraper including a plurality of blades and configured to engage the wellbore tubular in which the permanent bridge plug is to be set. The wellbore has a wellbore tubular having an internal diameter surface. When deployed, the integral permanent bridge plug assembly is configured to both scrape the internal diameter surface of the wellbore tubular and set an isolation barrier in a single trip into the wellbore.

摘要： A method of removing dope from a tubing system in a wellbore includes the step of, prior to setting a production packer, reverse circulating fluid within a tubing-casing annulus (TCA) so that is flows from the tubing-casing annulus into a first tubing and propels at least one wiper plug within the first tubing in an uphole direction, thereby wiping the inside of the first tubing and removing excess dope.

摘要： A mechanical drilling and removal tool and method for use in wireline and other operations for drilling through and removing paraffin, scale and other deposits from tubing in oil wells, all without the need for any electrical or hydraulic input to the tool, the tool comprising: (a) a tool body having an outer surface removably engageable with the inner wall of oil well tubing and having a threaded inner surface for receiving a threaded shaft, the outer surface of the tool body being engageable with the inner wall of oil well tubing when a rapid dynamic upward force is applied to the tool body and being disengageable when a steady upward force is applied; (b) a threaded shaft having a head end, a threaded body, and a threaded bit end and having the body threads complementary to the threaded inner surface of the tool body, the shaft being movable longitudinally downward through the tool body when a downward force is applied to the head end while the tool body is engaged with the inner wall of oil well tubing, thereby causing the shaft to rotate within the tool body and causing the threaded bit end to drill into and collect between paddle threads on the bit a deposit disposed below the tool body; and (c) a ratchet, attached to the head end portion of the shaft, to prevent the shaft from rotating when the shaft is moved longitudinally upward, thereby allowing the entire drilling and removal tool, along with the collected deposit, to be removed from the oil well tubing when a steady upward force is applied to the head end of the shaft. The bit can be a separate piece removably connected to the threaded shaft.

摘要： A method includes inserting a flexible cable into a cleaning region of a channel of a component via a cleaning port, rotating the flexible cable about an axis within the channel to interact a tip with deposits disposed within the cleaning region of the channel, moving the flexible cable within the cleaning region of the channel along a length of the channel, and removing portions of the deposits from the cleaning region of the channel via a second port. The flexible cable includes the axis and the tip. A diameter of the tip is different than a diameter of the flexible cable. The tip is configured to loosen the portions of the deposits.

摘要： A BOP cleaning tool includes a first pipe section with a through central channel and radial channels to external fins, with nozzles for flushing fluid from the central channel out into a BOP bore for washing cavities in the BOP bore, the central channel provided with a flow control sleeve provided with holes, the flow control sleeve displaceable from a radially closed initial first closed position to a second position with the holes aligned with the inner radial channels for starting flushing through the nozzles, and further displaceable to a radially closed third position with the holes out of alignment with the inner radial channels for halting the flushing through the nozzles. The flow control sleeve is displaceable from the first, initial position by a first dart dropped into the first pipe section and stopping in a first seat in the flow control sleeve below the holes, thereby closing the central channel, building pressure in the central channel, displacing the flow control sleeve to the second position and redirecting pipe flow to the nozzles. Flow control sleeve is displaceable from the second position to the third, closed position by a second dart dropped into the first pipe section and stopping at the first dart, the second dart blocking the holes thereby building pressure in the first pipe section, further displacing the flow control sleeve to the third position triggering a release mechanism for the first seat to release the first dart and the second dart.
