The specific embodiment
As shown in Figure 1-Figure 3, the present invention includes many sampling control module 1 and many sampling tubes module 2.Many sampling control module 1 are used for many sampling tubes module 2 is controlled, and many sampling tubes module 2 is used for formation fluid is taken a sample.
Many sampling control module 1 outside is cylindrical tube shape housing 11, and this housing 11 is detachably installed, so that the many sampling control module 1 of maintaining.In this housing 11, be provided with Address Recognition unit 12 and banked direction control valves control unit 13.Wherein, Address Recognition unit 12 is used for identification address, and sends the address information after this identification to banked direction control valves control unit 13.
After banked direction control valves control unit 13 receives address information after this identification, according to the electromagnetic valve sending controling instruction of this address information to corresponding sampling tube 211, with 211 opening and closing of control sampling tube, realize the control to sampling tube 211 sampling operations.
Also be provided with bearing toggle switch 14 on many sampling control module 1 housings 11 surfaces, this bearing toggle switch 14 can bear larger pressure, to adapt to the sampling operating environment.This bearing toggle switch 14 can be from the address of outside Set arbitrarily Address Recognition unit 12, thereby has simplified the wiring in many sampling control module 1, so that the present invention can infinitely expand.
2 connections of many sampling tubes module are arranged on many sampling control module 1 one ends.In the present embodiment, many sampling tubes module 2 comprises two groups of sampling tube groups 21, and every group of sampling tube group 21 comprises 3 sampling tubes 211.These 3 sampling tubes 211 evenly distribute take axial line as center of rotation diametrically, and these 3 sampling tube 211 extending directions are that many sampling tubes module 2 is axial.
Many sampling tubes module 2 comprises 6 sampling tubes 211 altogether in the present embodiment, and for single sampling tube, sampling efficiency has improved 6 times, and according to the needs of reality sampling operation, the quantity of sampling tube 211 can also continue to expand.The open and close of these 6 sampling tubes 211 are all controlled by banked direction control valves control unit 13.
