Description
Technical field
This utility model relates to the process pipe string in a kind of oil-gas field development field, especially one can be with one
Time tubing string carries out a point multilamellar formation testing, can a formula of the selectivity any one layer of operation or any several layers divide again
Layer oil testing tech tubing string.
Background technology
Current prospect pit, the Oil testing technique of evaluation well have defined a set of ratio more completely connection and have tried
Oil test series, but existing Oil testing technique and instrument are still limited to for a certain certain layer position
Carry out Oil testing, for return under needing formation testing or on return the formation testing of straddle test, current technique is still
So there is defect.Carrying out multilamellar formation testing by layer technique with one-trip string is becoming greatly of Oil Test Technology development
Gesture.
Utility model content
Technical problem to be solved in the utility model is to provide an a kind of formula formation testing by layer process duct
Post, carries out the formation testing by layer to multilamellar with one-trip string, formation testing complete alternative go into operation any one layer or
Any several layer.
For solving the problems referred to above, the technical solution adopted in the utility model is: a kind of formula layering examination
Oil process pipe string, including the back taper set gradually from down to up, is located pipe nipple, the support of band slips and uses
The compression packer of hydraulic setting, the first sliding sleeve that can repeatedly switch, a Y341 packer,
Two sliding sleeves that can repeatedly switch, the 2nd Y341 packer, throwing-dragging type unaflow valve blocking machine, pressure transmission torr
Rubber bowl, hydraulic jet pump, all connected by oil pipe between above-mentioned each parts.
Open, when closing sliding sleeve that the first sliding sleeve that can repeatedly switch and second can switch repeatedly, need
With steel wire or coiled tubing by under supporting selectivity sliding sleeve switch instrument in sliding sleeve, pass through steel wire operation
Or the jarring action of continuous oil pipe operation makes sliding sleeve be turned on and off.
Described hydraulic jet pump, throwing-dragging type unaflow valve blocking machine, pressure transmission torr rubber bowl, a Y341
The minimum diameter of packer and the 2nd Y341 packer is all higher than outside the maximum of selectivity sliding sleeve switch instrument
Footpath, more than the support of band slips and the minimum diameter of the compression packer using hydraulic setting, band slips props up
The minimum diameter of the compression packer of support and employing hydraulic setting is more than the maximum inner diameter being located pipe nipple.

Sliding sleeve the 4, the oneth Y341 packer 5, second that can repeatedly switch every device 3, first can switch repeatedly
Sliding sleeve the 6, the 2nd Y341 packer 7, throwing-dragging type unaflow valve blocking machine 8, pressure transmission torr rubber bowl 9,
Hydraulic jet pumps 10 etc., are all connected by oil pipe 11 between above-mentioned each parts.
Be located when pipe nipple 2 is gone into the well and be in upper and lower connected state, need close basecoat time, under enter to join
Set blanking plug, will be located joint blocking, when needing to reopen basecoat, under enter blanking plug recovery
Blanking plug is pulled out by instrument.
During sliding sleeve 4 and 6 that opening and closing can switch repeatedly, need will join with steel wire or coiled tubing
To in sliding sleeve under the selectivity sliding sleeve switch instrument of set, by steel wire operation or the jarring of continuous oil pipe operation
Effect makes sliding sleeve be turned on and off.
It is any one that selectivity sliding sleeve switch instrument alternative is turned on and off in multiple identical sliding sleeve
Individual.
Described hydraulic jet pump 10, throwing-dragging type unaflow valve blocking machine 8, pressure transmission torr rubber bowl 9, Y341
The minimum diameter of packer 5 and 7 is all higher than the maximum outside diameter of selectivity sliding sleeve switch instrument, more than band card
Watt support and use the minimum diameter of compression packer 3 of hydraulic setting.Band slips supports and uses liquid
The minimum diameter of the compression packer 3 that pressure sets is more than the maximum inner diameter being located pipe nipple 2.
When tubing string is gone into the well, the sliding sleeve 4 and 6 that can repeatedly switch is all in closed mode.
