Purpose.
In order that those skilled in the art more fully understand the present invention program, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.
With reference to Fig. 1, a kind of electrical block diagram for direction discernment circuit embodiments of logging well of the present invention, the well logging are shown
Direction discernment circuit 100 can include：
Depth transducer 101 with A roads output end and B roads output end；
Double D trigger 102；
First NAND gate 103 and the second NAND gate 104；
The data terminal of the double D trigger 102 is connected with A roads output end, clock triggering end and B roads output end
It is connected；
The first input end of first NAND gate 103 is connected with A roads output end, the second input and described couple of D
The in-phase output end Q of trigger 102 is connected；
The first input end of second NAND gate 104 is connected with B roads output end, the second input and described couple of D
The reversed-phase output of trigger 102It is connected；
Wherein, the phase difference between the first via output and second tunnel output is 90 °；
When first NAND gate 103 is output as high level, it is determined that well logging direction is downward；
When second NAND gate 104 is output as high level, it is determined that well logging direction is upward.
In the present invention, well logging direction discernment circuit 100 includes depth transducer 101, Double bottom trigger, the first NAND gate
