3, a kind of method of intelligent seal-testing flow-measuring and adjusting, it is characterized in that: the control circuit flow process of a kind of intelligent seal-testing flow-measuring and adjusting instrument as claimed in claim 2 is: (a) main control CPU is connected with power supply, PC interface (227) is connected with main control CPU, upward pressure sensor (224), lower pressure sensor (237) is connected with three A/D converters respectively with flow transmitter (226), three A/D converters are connected with the corresponding signal port of main control CPU respectively, last motor (27), following motor (20) is connected with two control circuits respectively, and two control circuits are connected with main control CPU corresponding signal port respectively; (b) connect (227) by PC and required controlling parameter is set to main control CPU; (c) in flow-measuring and adjusting: flow transmitter (226) will detect the flow signal of place layer at any time and import in the main control CPU after the A/D converter conversion, judging actual flow after main control CPU is handled is to be greater than or less than parameter is set, and control signal is outputed in the control circuit that is connected with last motor (27) according to judged result, (27) positive of motor in the control or reverse rotation, make pilot plunger (111) downlink or uplink, regulate water hole (116) and cross the size in water cross section, thus the debugging flow; Test in the envelope in test, motor (20) switch time is set on ground down, make transmission mechanism (232) drive sealed plunger (216) downlink or uplink, close or open individual layer weep hole (233), then, upward pressure sensor (224) detects strata pressure, lower pressure sensor (237) detects water injection pressure, and respectively pressure signal in the input main control CPU, according to the pressure drop between water injection pressure and strata pressure, is judged whether packer seals after the A/D converter conversion;
Specific operation process is:
In the inclined to one side hole of the eccentric injection mandrel (3) of each layer, drop into a kind of adjustable blanking plug as claimed in claim 1; In the centre bore (32) of eccentric injection mandrel (3), drop into a kind of intelligent seal-testing flow-measuring and adjusting instrument as claimed in claim 2, accurately lead through the centralizer body (33) in the eccentric injection mandrel (3) by guide way (229), and when a kind of intelligent seal-testing flow-measuring and adjusting instrument as claimed in claim 2 passes through the centre bore (32) of eccentric injection mandrel (3), last retaining mechanism (24) is opened cursor (25), following retaining mechanism (222) is opened positioning wedged block (221), on carry certain distance, transfer again and make positioning wedged block (221) seat on the support (31) of eccentric injection mandrel (3), rotate the fishing head in many ways (11) that slips (29) blocks a kind of adjustable blanking plug as claimed in claim 1 simultaneously; Last leather cup (213) leans on upper sliding sleeve (211) and low sleeve (214) and low sleeve (214) and supporter (220) relative displacement distending with down cup (218), be sealed in respectively on the upper and lower sealing surface of eccentric injection mandrel (3) inwall weep hole (30), individual layer weep hole (233) is communicated with weep hole (30) on the eccentric injection mandrel (3);
When the force value of lower pressure sensor (237) or detected water filling of upward pressure sensor (224) or bloated sealed packer surpasses the starting pressure that a kind of intelligent seal-testing flow-measuring and adjusting instrument as claimed in claim 2 is provided with on ground, motor (27) rotation is gone up in main control CPU control, drive link (28) driven rotary slips (29) and fishing head (11) rotation in many ways, pilot plunger is moved on (111), making controlled water chew (113) is communicated with water hole (116), and the size in the water flowing cross section of the adjustable size of pilot plunger (111) Top Runby joint water hole (116), reach the size that ground is provided with thereby make controlled water chew (113), and normal water filling;
After water filling a period of time, main control CPU control motor (20) rotation down in as claimed in claim 2 a kind of intelligent seal-testing flow-measuring and adjusting instrument of next stage makes sealed plunger (216) close individual layer weep hole (233) and tests envelope work; After this layer is tested envelope and finished, move on the sealed plunger (216) and open individual layer water injection hole (233), the normal water filling of this layer;
In last layer or arbitrarily one deck repeats operation process, carries out this layer and tests envelope;
Treat that all layers test envelope and finish, pressure system balance behind the water filling certain hour, flow transmitter (226) begins survey to transfer the individual layer flow; When survey laminar flow amount is greater than or less than the ground value of setting, main control CPU control is gone up motor (27) and is rotated forward or backwards, drive pilot plunger (111) downlink or uplink, change the size of crossing the water cross section of water hole (116), when water injection rate is identical with the ground value of setting, last motor (27) stops the rotation, and finishes the work of transferring each individual layer water injection rate of surveying;
Pull a kind of intelligent seal-testing flow-measuring and adjusting instrument as claimed in claim 2 from top to bottom successively out, computer is connected with PC interface (227), playback can obtain data information.
