The record test stressor layer of manometer 2 of external pressure is surveyed, sampler 5 is sampled in process fluid flow, unsealed after the completion of operation
Two packers act downhole tool, carry out setting-out in face of sample in sampler 5 on ground, open eduction valve 7, volume of releasing
Liquid in cylinder 6；
The function that cable is layered component in rapid determination tube column is as follows：
Electric packer 1, lower electric packer 4 on 1.：Predominantly separate test zone, setting force and deblocking power from
Annular space head of liquid；
2. relief valve 3：After packer setting, relief valve 3 is opened, is that the annulus fluid between two packers flows into volume
Cylinder 6 establishes current by pass, and the operating force of relief valve 3 is also from annular space head of liquid；
3. the external manometer 2 for surveying external pressure：Measure test stressor layer；
4. sampler 5：Test layer sample is taken, carries out setting-out on ground；
5. volume cylinder 6：The annulus fluid between two packers is stored, volume cylinder 6 is initially air collector, volume cylinder 6
Volume, which can according to need, to be designed, and after relief valve 3 is opened, annular space well killing fluid is flowed under the influence of gravity into volume cylinder 6, to
After kill-job liquid stream between two packers is complete, the outflow of test layer product；
6. eduction valve 7：Mechanically actuated, on ground, the liquid in volume cylinder 6 is drained；
7. centre bore, main spindle and the centre bore of lower contact, sampler 5 and appearance of top connection in lower electric packer 4
Product cylinder 6 is the space of annulus fluid excretion after two packer settings；
Wherein, upper electric packer 1 and lower 4 working principle of electric packer are：When packer is just installed into, set electronic
Push rod 8 and deblocking electric pushrod 9 are in elongation state, set the O-ring closing on electric pushrod 8 and set runner 15, deblocking electricity
Dynamic push rod 9 closes deblocking runner 16 under the auxiliary of sealing ring；
When setting, the starting that is powered sets electric pushrod 8, makes to set the contraction of electric pushrod 8, opening sets runner 15, sets
Electric pushrod 2 powers off, and is maintained at push rod contraction state, annulus fluid sets cavity 18 along the arrival of runner 15 is set, in differential pressure
The motoricity to its 26 direction of lower contact is generated in mandrel 10, differential pressure mandrel 10 and upper jack rabbit 23 are together to its lower contact 26
Direction movement, first cuts off 21, continues to move to the direction of its lower contact 26, compresses packing element 24 to setting completely, fluid column pressure
Power always exists, so packer can be always held at the state of setting at this time；
When deblocking, be powered starting deblocking electric pushrod 9, makes to unseal the contraction of electric pushrod 9, opens deblocking runner 16, deblocking
Electric pushrod 9 powers off, and is maintained at push rod contraction state, annulus fluid reaches deblocking cavity 19 along deblocking runner 16, due to solution
Envelope 19 area of cavity, which is greater than, sets 18 area of cavity, and the power moved to its 14 direction of top connection is generated in pressure difference mandrel 10, is pressed
Poor mandrel 10 and upper jack rabbit 23 are moved to its 14 direction of top connection together, and upper jack rabbit 23 is against on jointing 22 not completely
