The present invention mainly comprises self power generation ultrasonic atomizatio under (1) input floatation type self power generation ultrasonic atomizing device B, (2) launching trapDevice A, three key steps of (3) opening well and making production. Specific as follows:
(1) throw in floatation type self power generation ultrasonic atomizing device B
As shown in Figure 1, when input, meet floatation type self power generation ultrasonic atomizing device B and this instrument is passed through with rope tool series windingGas production wellhead E transfers to the following design attitude of pit shaft C bottom hydrops liquid level D, slowly goes up rope rope, as shown in Figure 3, makes theTwo slips 21 move down with respect to all parts of the second body 22 and connection therewith and are stuck in tube inner wall, rope rope in continuationString out outside pit shaft C with rope tool until cut off the second shear pin 19, the second dispensers 17, floatation type self power generation is ultrasonicAtomising device B throws in successfully.
(2) self power generation ultrasonic atomizing device A under launching trap
As shown in Figure 1, when input, with rope tool string connecting downhole self power generation ultrasonic atomizing device A and by this instrument by adoptingGas well mouth E transfers to condensed liquid and starts appearance place, slowly goes up rope rope, as shown in Figure 2, makes the first slips 6 with respect to firstBody 5 and cone seat 7 move down and are stuck in tube inner wall; Rope rope in continuation, makes cylinder fixture block 10 and the first noumenon of cone seat 75 fishbone button 32 engages, and now, the first noumenon 5 with respect to moving on cone seat 7, promotes the first packing element together with the first overcoat 1211 strut, and reach pre-sealed effect (in the time of opening well and making production, because instrument is upper and lower thereby the first packing element 11 is contacted with pit shaft CThere is pressure reduction in trip, the first overcoat 12 continues to strut the first packing element 11, reaches the effect fully sealing with pit shaft C); Upper rope ropeString with rope tool until cut off the first shear pin 3, the first dispensers 1 that the first dispenser 1 is connected with the first noumenon 5Go out outside pit shaft C self power generation ultrasonic atomizing device A success under launching trap.
(3) opening well and making production
Open gas production wellhead E and produce valve, pit shaft C high speed air-flow starts pipeline outflow earthward. Due to the second packing element 23 withThe first packing element 11 and Well-wall sealer, high velocity air will drive by the perforate 31 of leaning to one side of the first overcoat 12, the second overcoat 24One vane rotary device 15, the second vane rotary device 27 High Rotation Speeds, thus make first/electrical storage device 16, second/electrical storage device28 generatings accumulate with and provided for the first ultrasonic atomizatio generator 14, the second sonic oscillation atomizing generator 26 by transmission electric wirePower, the first ultrasonic atomizatio generator 14, the second sonic oscillation atomizing generator 26 will be droplet by liquid phase atomization.
Because flotation tank 29 is subject to the buoyancy of shaft bottom hydrops, impel and on the second overcoat 24, push away the second packing element 23, the second packing elements 23Axial compression occurs will be sealed with pit shaft C barrel. Pit shaft C bottom liquid can only be by the second vane rotary device 27 newelsCylindrical hole 33 to second sonic oscillation atomizing generator 26, the second sonic oscillation atomizing generators 26 just liquid phase is atomized into littleDrop also moves from the second body 22 center cavities with air-flow;
Because the first packing element 11 fully seals with pit shaft C, can be at the first packing element 11 along the defluent condensed liquid of pit shaft C barrelAssemble with pit shaft C gap, in the time that condensed liquid exceedes the first noumenon 5, will flow to liquid cylinder along the first noumenon 5 center cavity inwalls13, the first ultrasonic atomizatio generators 14 will be droplet by interior liquid cylinder 13 condensed liquid atomization; Air-flow is by the first overcoat 12The lean to one side gap of perforate 31 and liquid cylinder 13 is carried droplet and on the center cavity by the first noumenon 5, is moved.
When shaft bottom hydrops liquid level D (is that liquid level D is lower than floating lower than floatation type self power generation ultrasonic atomizing device B certain distance relativelyWhen case the 29 bottom), the suffered buoyancy of flotation tank 29 reduces or is not subject to buoyancy, its gravity Main Function to drive the second overcoat 24 to move down,The second packing element 23 occurs axially to uphold and pit shaft C barrel depressurization; Flotation tank 29 continues to move down drive the second body 22 and moves down,Thereby make the second slips 21 releases, floatation type self power generation ultrasonic atomizing device B entirety moves down; When flotation tank 29 immerses well again, the suffered buoyancy of flotation tank 29 is greater than gravity and upwards pushes away the second overcoat 24, short when the following Theoretical Design of prodelta clay liquid liquid level D the positionMake the second packing element 23 again with Well-wall sealer, the second body 22 contact with the second slips 21 deciphering again, the second slips 21 andThe borehole wall is stuck; Floatation type self power generation ultrasonic atomizing device B atomization shaft bottom hydrops again.
The invention described above embodiment sequence number, just to describing, does not represent the quality of embodiment.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all the spirit and principles in the present invention itIn, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
