Description
Technical Field
The invention relates to the field of oilfield technology development, in particular to a bidirectional sealing flow-collecting type flow regulator.
Background
At present, in the process of oil field development, the liquid level of an oil well is gradually reduced after an oil layer is produced to a certain degree, when the liquid level is reduced to the certain degree, a part of the oil well needs to be changed into a water injection well, the liquid level of the oil well is improved through water injection, and the oil pumping unit is convenient to produce oil. Because the thickness, permeability and porosity of each layer of the oil layer are different, separate layer water injection is required according to the condition among the layers of each well. The underground water injection pipe column of the water injection well is required to be provided with a packer (used for dividing an oil layer and preventing the two layers from communicating), a layered water distributor (used for distributing the water injection quantity of the oil layer), and a well flushing valve (used for reversely flushing the well through a sleeve when scale in the well is excessive, and flowing out of the well mouth through an oil pipe to bring out the scale under the well bottom). There are two main types of water distributors: one is a water distributor with a fixed water nozzle (the fixed water nozzle is arranged before the water distributor goes into the well to limit the water injection amount, and the water distributor has the defects of large error of layered water injection and complicated allocation); the other type is an adjustable water distributor, an adjustable water nozzle is installed in the adjustable water distributor, a well descending instrument is located on a positioning step of the water distributor, a test cable is connected with the well descending instrument through a ground generation instruction, then the water nozzle on the water distributor is adjusted by an adjusting instrument, and the layered water injection quantity is controlled by rotating an adjustable water distribution core. The water injection quantity measured by the instrument is obtained by a subtraction method, and the water injection quantity of each layer (the instrument is calibrated in a standard oil pipe when the flow is calibrated) is obtained by the measured water injection flow rate. In the long-term water injection process of a downhole oil pipe, the measurement error is large due to serious scaling in the oil pipe, so that the water injection quantity of each layer to be adjusted also generates great error. The current testing and adjusting method is changed, the testing and adjusting precision and accuracy of water injection of each layer are greatly improved, the working efficiency is improved, the production cost is reduced, and the economic benefit is increased.

The working principle of the invention is as follows:
the upper end of the steel wire armored test cable is connected with a ground control box, the lower end of the steel wire armored test cable is connected with a bridle circuit 1, the bridle circuit is connected with an underground instrument control circuit 2, and the underground instrument control circuit is communicated with a slip ring 5 at the lower end of a bidirectional sealed current-collecting type flow regulator through a current-collecting type flowmeter 3. And a ground control box sends a control instruction to command the underground control circuit, the flow-concentrating flowmeter and the bidirectional sealing flow-concentrating flow regulator to work. The invention mainly explains the working principle of the bidirectional sealing flow-collecting type flow regulator and the mutual relation of the self-locking anti-reverse-flow bridge type concentric adjustable water distributor of the layered water injection well related to the bidirectional sealing flow-collecting type flow regulator:
in the figure, 1, 2, 3 and 4 are instruments and assembly parts which are connected with a bidirectional sealed flow-concentrating type flow regulator in a well. When the ground control box supplies positive power to the upper direct current motor, the upper direct current motor drives the planetary gear reducer 13 to rotate, the rotating speed is reduced through the planetary gear reducer, and the torque is increased to drive the upper torsion screw 15 to rotate. The upper torsion screw 15 is connected with the central screw 19, holes for passing wires are arranged on the central screw 19 and the upper torsion screw 15, and a circuit coming out from the wire passing hole at the lower end of the central screw is connected with the lower motor through a two-core slip ring 17. The upper direct current motor 12 mainly functions to drive the central screw rod 19 to rotate forward and backward by the forward and backward rotation of the upper direct current motor through a ground instruction. When the central screw rod 19 rotates reversely, the lower end of the central screw rod 19 cooperates with the screw sleeve 37 to drive the screw sleeve 37 to move downwards. The screw sleeve 37 pulls the opening connecting sleeve 38 to drive the blocking sleeve 36 to move downwards, the blocking sleeve 36 is connected with the switch sleeve 33, and the switch sleeve 33 is connected with the two leather cup fixing sleeves 30 through screws and is connected with the positioning claw fixing sleeve 22 provided with the positioning claw 23. When the two leather cup fixing sleeves 30 and the positioning claw fixing sleeve 22 move downwards to a certain position under the driving of the switch sleeve 33, namely the leather cup 31 leaves the taper sleeve 29, and the positioning claw 23 retracts into the positioning claw fixing sleeve 22, the sliding screw block 16 on the upper torque screw 15 touches the limit switch, the power supply of the upper direct current motor 12 is cut off, the upper direct current motor stops rotating, and the contraction state of the two leather cups 31 and the contraction state of the positioning claw 23 are completed. When the invention is put into a well and put on a self-locking anti-reverse-flow bridge type concentric adjustable water distributor for layered water injection, the bidirectional sealing current-collecting type flow regulator needs to be powered positively, the upper direct current motor 12 drives the relevant mechanisms and parts to rotate positively, the screw sleeve 37 moves upwards to push the large pressure spring 35 to push the switch sleeve 33 to move upwards, and the switch sleeve 33 drives the two leather cups 31, the positioning claws 23 and the fixed sleeve 34 to move upwards synchronously. When a certain position is reached, the limit switch stops the rotation of the upper direct current motor 12, at this time, two leather cups and a positioning claw are fixed on a rotating core of a self-locking anti-reverse-flow bridge type concentric adjustable water distributor installed on an underground water injection pipe column, injected water of a water injection well passes through a flow-concentrating type flowmeter and two side channels in a two-way sealing flow-concentrating type flow regulator, then passes through water outlets of the flow regulator and a middle water outlet of the rotating core of the self-locking anti-reverse-flow bridge type concentric adjustable water distributor, and because two water outlets corresponding to the rotating core are also formed in a main body of the self-locking anti-reverse-flow bridge type concentric adjustable water distributor, the water distributor can only discharge water when the two water outlets are communicated. The size of the overlapping area of the rotary core and the position of the water outlet hole on the self-locking anti-reverse-spitting bridge type concentric adjustable water distributor is changed, so that the water yield is changed. The size of the water flow is controlled by a ground control box to enable a lower direct current motor to work, the rotation of the rotating core in the positive and negative directions is changed through the positive and negative rotation of the lower direct current motor, and the rotation of the rotating core changes the size or the on and off of the water flow of the self-locking anti-reverse-spitting bridge type concentric adjustable water distributor.
The working principle of the lower part of the bidirectional sealing flow-collecting type flow regulator is as follows:
when the ground control box gives an instruction, the lower direct current motor drives the planetary gear reducer to rotate, the output shaft of the planetary gear reducer 13 drives the torque sleeve 50, the torque sleeve drives the lower torque screw 46, the lower torque screw drives the torque screw (54) to rotate, the rotation of the torque screw drives the sliding screw block 53 to move up and down, the sliding screw block 53 rotates slowly in the lower spiral groove of the fixed anti-rotation sleeve 45, two ends of the sliding screw block 53 are associated with the fork-shaped torque sleeve, when the sliding screw block 53 rotates and moves along the spiral groove of the fixed anti-rotation sleeve, the torque sleeve 55 also rotates slowly correspondingly, and the mechanism is designed to reduce the rotating speed and increase the torque, namely, reduce the rotating speed by 30 times and increase the torque by more than 20 times. The lower end of the torsion shaft sleeve 55 is connected with a torsion arm main body 61, a torsion arm 59 is arranged on the torsion arm main body 61, a large roller 56 is fixed on the torsion arm by a pin, when the torsion shaft sleeve 55 rotates, the torsion arm main body 61 is driven to rotate, and the torsion arm 59 and the large roller 56 are inserted into a fixed anti-rotation sleeve groove of the self-locking anti-reverse-flow bridge type concentric adjustable water distributor, so that the effect of preventing the lower end of the bidirectional sealing flow collection type flow regulator from rotating is achieved, the reaction force drives a rotating core at the upper end of the self-locking anti-reverse-flow bridge type concentric adjustable water distributor to rotate in the forward and reverse directions, and the effects of collecting and adjustable stratified water injection are achieved.
