In order to better illustrate a kind of sampling process of sampler under smart well of controlled in wireless, shown in reference Fig. 6, can
It is divided into four-stage.
A. sample the preparatory stage.First with actuator, sampler body (1) is carried to well head, by hold-down bars (4)
So that convex switch (113) closes in insertion interim fixing hole (112), and this switching signal is sent into power control circuit
(1221) in, open the power supply of sampler body (1).Recycle wireless remote controller (2) that sampler body (1) is carried out
Sampling mode is arranged, and wherein sampling mode is divided into automatic timing mode and Manual ground control model, after setting success, wireless remote
By Chang Liang, hold-down bars (4) takes out the display lamp (24) of the corresponding function in control device (2) the most at last, completes this stage.
B. go into the well sample phase.By operating actuator, sampler body (1) is at the uniform velocity transferred to down-hole, arrival refers to
After determining sample position, stop the movement of sampler body (1) and wait it to complete to sample.
C. sampling completes to carry the stage.After reaching sample time, by operating actuator by sampler body (1)
At the uniform velocity above carry to well head.
D. turn the sample stage.The oil-feed connecting hole (32) of antispray sampling cup (3) is connected going out to sampler body (1)
After oilhole (137), by turning sample function button in the button (25) of wireless remote controller (2), remotely control sampler this
Body (1) first opens oil outlet (137), after open fuel feed hole (135) again, make sample by action of gravity flow into antispray sampling cup
(3) in.Observe sample capacity using scale (35), when reaching after needing capacity of sample of sampling, again by wireless remote control dress
Put and turn sample function button in the button (25) of (2), close oil outlet (137) and fuel feed hole (135), complete to turn sample.
Separately, because the fluid reservoir (136) of sampler body (1) holds than the sampling cup (34) of antispray sampling cup (3)
Amount is big, therefore after the completion of turning sample, in fluid reservoir (136) still can residual fraction sample, for ensureing the accurate of lower sub-sampling sample,
That can pass through wireless remote controller (2) turns sample function, by the residual sample emptying of fluid reservoir (136).
System, when carrying out well sampling, can complete to sample by two kinds of sampling modes, in order to better illustrate both
The flow process of pattern, with reference to shown in Fig. 7.
After the electric power starting of sampler body (1), pattern is sampled to it by wireless remote controller (2) and remotely sets
Put.
When selecting to be set to automatic timing mode, according to the speed of going into the well of sampler body (1), calculate and reach sampling
The time of depth, and be timing by remote setting, central processing circuit (1223) will open timer internal, start to count
When, wireless remote controller (2) synchronization opening timing, after reaching timing, the buzzer (23) of wireless remote controller (2) is sent out
Go out sound, remind and reached precalculated position, then stop actuator；Central processing circuit (1223) judges timing simultaneously
Arrive, automatically open up fuel feed hole (135), be sampled, and start default timing sample time, after sample time arrives, close into
Oilhole (135), completes whole sampling process；Wireless remote controller (2) is also synchronous to be sampled time timing, judges sample time
To then driving buzzer (23) to send sound, sampling is reminded to complete.
Separately, in sampling, during from load push-pull (131) drive push-pull bar (132) to the movement of load push-pull (131) direction, taper
Blanking plug (134) and piston (133) will move in fluid reservoir (136) simultaneously, and successively open oil outlet (137) and fuel feed hole
(135), sample is then by gravity and gas pressure, full of whole fluid reservoir (136)；According to sample be full of fluid reservoir (136) when
Between setting sample time.
When selecting to be set to Manual ground control model, the acceleration transducer (1222) of control circuit (122) is taking
Sampling device body (1) at the uniform velocity go into the well during its kinestate of real-time monitoring, and acceleration signal is sent into central processing circuit
(1223) calculated in and analyzed；After reaching depth selection, sampler body (1) is controlled to enter by ground actuator
The movement of the specific rule of row and stopping, thus complete specific kinetic characteristic.For example, one of predetermined movement characteristic is sampler
Body (1) is stopped by positive uniform motion to short time, when sampler body (1) is at the uniform velocity to down-hole positive movement to specific bit
Postpone, control sampler body (1) to stop moving by ground actuator, central processing circuit (1223) is according to acceleration
The detection signal of sensor (1222) knows that the kinestate of sampler body (1) is changed into stopping from positive uniform motion, and
More than 5 seconds, central processing circuit (1223) then controlled load push-pull (131) by control signal output circuit (1224) to dwell time
Open fuel feed hole (135)；And after reaching sample time, close fuel feed hole (135) and complete to sample.In the same manner, predetermined movement characteristic
Also can be for stopping to reverse uniform motion, positive uniform motion to reverse uniform motion, positive short time uniform motion for a long time
Stop etc. to the short time, thus realizing in well head to the different control signals of down-hole transmission.
