The external threads of the upper joint are connected with the internal threads of the packer, the external threads of the eccentric pipe are connected with the internal threads of an eccentric hole of the upper joint, and the internal threads of the lower joint are connected with the external threads of the packer. An upper baffle plate and a lower baffle plate which are arranged on the lower middle part of the packer clamp the root of an eccentric disc, are penetrated by the eccentric pipe form the central hole, and are tightly pressed by a pressing sleeve to play a sealing and isolating function. The controller solves the problem of the production uninterrupted sand cleanness of the pumping well.
Description
The utility model relates to pumpingh well oil production technology, downhole tool technology, particularly is a kind of pumpingh well sand washing controller that do not stop production.
Pumpingh well has arrived development late stage owing to the oil field in process of production, and oil reservoir shakes out in a large number, must take the oil reservoir sand control measure, because of often causing oil layer blocking behind the formation sand production, well inner product sand can't be gone out, cause oil well to stop production when serious, need operation again, oil well is resumed production.Prior art can not satisfy present oil field pumping well and produce needs, can not solve above-mentioned existing problems.
The purpose of this utility model is at the prior art weak point, designs a kind of pumpingh well sand washing controller that do not stop production.Separate the sand washing problem that never stops production.Above-mentioned purpose is realized by following technical proposals:
This pumpingh well does not stop production the sand washing controller by top connection, eccentric pipe, packer, lower contact four parts are formed, it is characterized in that top connection is positioned at the packer upper end, eccentric pipe is positioned at packer centre bore eccentric position, lower contact is positioned at the packer lower end, the top connection external screw thread connects with the packer internal thread, the internal thread of eccentric pipe external screw thread and top connection eccentric orfice links, lower contact internal thread and packer external screw thread link, therein the bottom set on, lower baffle clips eccentric packing, eccentric pipe is from last, lower baffle, eccentric packing eccentric orfice center is passed, gland external screw thread and lower contact aperture internal thread link, to go up, lower baffle, eccentric packing is fixed on the lower contact inner chamber, and eccentric pipe fixed, constitute an integral body.
Above-mentioned oil pumper does not stop production, and top connection top is internal thread in the sand washing controller, and the bottom is an external screw thread, and endoporus is provided with an eccentric semi-round ring shape through hole and an off-centre operation cylindricality endoporus, and is provided with internal thread in the hole, and vertical the communicating of clear opening that is provided with top.
Lower contact profile in the above-mentioned sand washing controller that do not stop production is identical with top connection, and the centre is a cylindrical hole, a ring-shaped step is arranged below uniform three the inside and outside clear openings on the circumferential same plane, middle part, 120 ° of angles, through hole.
Upper and lower plate washer in the above-mentioned sand washing controller that do not stop production presents cylindrical, is provided with through hole on the same axis of off-centre operation cylindricality endoporus of eccentric position and top connection.
The packing shape of the above-mentioned sand washing controller that do not stop production is identical with upper and lower plate washer shape, and thickness is oil-resistant rubber material greater than plate washer.
Gland in the above-mentioned sand washing controller that do not stop production presents tubular, and top is provided with external screw thread, and lower bottom end is provided with symmetrical through hole.
The above-mentioned sand washing controller that do not stop production is used fashionable dress pipe arrangement post from top to bottom: oil pipe, oil well pump, top connection, packer, lower contact (interior dress sand clean out pipe), tail pipe (3～4) oil pipe, wrapping wire pipe, plug head.
Technology is as follows in the above-mentioned sand washing controller that do not stop production: taking different measure according to the oil well downhole conditions, at first, is the high service source: the one, and can use cementing truck, tank car to supply water; The 2nd, adopt from the water injection well to the oil well on a fixedly water supply flow process; The 3rd, application activity formula water under high pressure tengential belt supplies water from the water injection well to the oil well.Secondly, can take fixedly water supply flow process, take water mixing sand washing under the pump, oil well be taken out of with output liquid in process of production, thereby prevented that sand from burying oil reservoir for the thick well of oil.The 3rd, can take regular sand washing for general well, application activity formula water under high pressure tengential belt is progressively groped the sand washing cycle according to the sand production situation.The 4th, flushing fluid sewage, 45～55 ℃ of water temperatures, pressure is answered-15MPa.
Advantage of the present utility model is that it is simple in structure, be convenient to make, unique off-centre design, passage is big, be convenient to sand is gone out, can solve casing deformation well, stratum sand proof well, sand control sand production problem not, prolong pump detection period, reduce operating cost, every mouthful of pumpingh well can reduce twice of operation every year, economize on the use of funds 80,000 yuan, significant for oil field development, be worthy of popularization.
For the clear technical scheme of announcing the application, be further elaborated below in conjunction with accompanying drawing 1,2,3:
Accompanying drawing 1: be that the rod-pumped well sand washing controller master that do not stop production looks the complete section structural representation
Accompanying drawing 2: the A-A that is accompanying drawing 1 is to view
Accompanying drawing 3: be upper and lower plate washer master TV structure schematic diagram in the accompanying drawing 1
In conjunction with the accompanying drawings enforcement of the present utility model is described below:
In the accompanying drawing, the 1st, top connection, the 2nd, packer rubber, the 3rd, packer, the 4th, sand clean out pipe, the 5th, last plate washer, the 6th, eccentric packing, the 7th, lower baffle, the 8th, gland, the 9th, lower contact.
The rod-pumped well sand washing controller assemble sequence that do not stop production is as follows: at first off-centre operation cylindricality endoporus D internal thread in the top connection 1 is connected with eccentric pipe 4 external screw threads; Second is connected top connection 1 bottom external screw thread with packer 3 upper end internal threads; The 3rd is connected lower contact 9 internal threads with packer lower end external screw thread; The 4th is will go up plate washer 5, packing 6, lower baffle 7 successively to be inserted in from sand clean out pipe 4, and above eccentric part and sand clean out pipe 4 off-centre are matched; The 5th, gland 8 is inserted in from sand clean out pipe 4, catch on gland base apertures G with the eave tile wrench, positive hour hands rotation makes its external screw thread be connected with lower contact 9 lower end internal threads, and up to compressing packing, assembling finishes.
The liquid flow aspect is as follows during sand washing: enter sand clean out pipe 4 centre bore Fs by oil sets annular space by hole B, C in the top connection 1 from water under high pressure on the ground, after liquid washes the outer oil reservoir sand of wrapping wire pipe by the wrapping wire pipe, liquid is taken behind the sand along returning on the oil casing annular space by hole E in the lower contact, enter packer 3 inner chambers, by top connection 1 inner semi-round ring shape A duct, enter tubing string and sand liquid is gone out ground again by the pressure of surface pump.
