Abstract
The utility model discloses a self-lifting type water-injecting and flushing pipe string for a flushing well, which comprises a water-injecting pipe string. The water-injecting pipe string comprises an upper water-injecting pipe string section and a lower water-injecting pipe string section which are connected with each ohter through a hydraulic lifter; the hydraulic lifter is connected wiht a ground pressure control device through fluid control pipelines; the ground pressure control device is used for controlling the hydraulic lifter to lift or take down the lower water-injecting pipe string section through the fluid control pipelines; insert seals matched with isolation packers of a separate injection well are arranged on the lower water-injecting pipe string section; anti-return spit water distributors are arranged between the adjacent insert seals and are fixedly installed on the lower water-injecting pipe string section; and the isolation packers are installed in the casing of the separate injection well. The utility model has the beneficial effects that the input of a large number of labors, equipment and well-flushing expenses before and after washing is avoided, the platform work space is saved, the well-washing operation process of a water injection well is simplified, the usage amount of the labors and the equipment is reduced, and the production cost of an oil field is saved.
Description
Technical field
The utility model relates to a kind of used for water injection wells in oil fields washing well notes and washes tubing string, and particularly a kind of the notes from the lift-type washing well washed tubing string.
Background technology
At present, in the oil field flushing operation, conventional clean-out service all is the pumping and washing process of mentioning several endowels on adopting: promptly needs are removed the well head production tree before the well-flushing, and preventer is installed, and remove tubing hanger and carry several endowels on also, carry out clean-out service again.After clean-out service finished, several oil pipes of carrying on need being lowered to before the operation were installed tubing hanger, remove preventer and production tree is installed, and resumed production then or injected.In clean-out service, not only to drop into great amount of manpower, equipment and high well-flushing expense; And at sea the oil field receives the platform space restriction; Various production operations are frequent, face well-flushing personnel and hold facility platform resource and space for a long time and stop the predicament of other operations.Therefore, be badly in need of that a kind of operation is simple, duty cycle is shorter, drop into manpower, the less notes cleaning device of equipment.
Summary of the invention
The utility model provides a kind of the notes from the lift-type washing well to wash tubing string for solving the technical problem that exists in the known technology, and these notes are washed the clean-out service process that tubing string can be simplified water injection well, and the use amount of minimizing personnel and equipment is practiced thrift the cost of production in oil field.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of notes from the lift-type washing well washed tubing string; Comprise water injection string; Said water injection string comprises top water injection pipe shell of column and the bottom water injection pipe shell of column that links to each other through hydraulic lifting apparatus; Said hydraulic lifting apparatus is connected with the ground pressure control device through liquid controling pipe line, and said ground pressure control device is controlled said hydraulic lifting apparatus through said liquid controling pipe line and promoted or transfer said bottom water injection pipe shell of column; Said bottom water injection pipe shell of column is provided with the insertion sealing adaptive with the separate water injection well isolation packer; Between adjacent said insertion sealing, be provided with anti-returning and tell injection well downhole flow regulator; Said anti-returning told injection well downhole flow regulator and is packed on the water injection pipe shell of column of bottom, and said isolation packer is installed in the seperated layer water injection casing.
The bottom of said bottom water injection pipe shell of column is provided with ball-and-seat.
Advantage and the good effect that the utlity model has are: be employed between top water injection pipe shell of column and the bottom water injection pipe shell of column hydraulic lifting apparatus be set, adopt on the hydraulic lifting apparatus and carry or transfer bottom water injection pipe shell of column, thus the opening and closing of realization water injection string well-flushing passage; Accomplish water filling operation and well-flushing; When guaranteeing the well-flushing quality, interlayer can restore fully and put in place in the time of can also guaranteeing restoring injection, has avoided the input of a large amount of manpowers in well-flushing front and back, equipment and well-flushing expense; Practiced thrift the platform working space; Simplify the clean-out service process of water injection well, reduced the use amount of personnel and equipment, practiced thrift the cost of production in oil field.Bottom water injection pipe shell of column, be provided with and prevent returning the structure of telling injection well downhole flow regulator and ball-and-seat, not only satisfied the needs of water injection well water filling and well-flushing, also realized full pit shaft well-flushing in the bottom.
