Detailed description of the invention
As shown in Figure 1, ground and underground equipment two-way communication inclinometer, downhole system comprises fishing head (1), centering ring (2), inserting tube control pipe nipple (3), battery short section (4), pulse signal generator (5), is threaded from top to bottom.As shown in Figure 2,3, ground system comprises pressure sensor (6), wireless pressure sensor main frame (7), wireless receiving and dispatching main frame (8), digital treating meter (9).Pressure sensor (6), wireless pressure sensor main frame (7) realize communicating respectively by embedded radio receiving transmitting module with wireless receiving and dispatching main frame (8), digital treating meter (9).
During instrument work, first use digital treating meter (9) pulse signals generator (5) to carry out work schedule setting, then connect downhole system, transfer to shaft bottom.In downhole system, the work schedule of pulse signal generator (5) is able to programme, by arranging certain sequential, producing alternating pulses signal and can stop in real time, open instrument, realizing ground and underground equipment two-way communication.When opening or close underground equipment, slush pump state such as the sequential on Fig. 4 carries out start-stop, first termination of pumping T time, then turn on pump, in T time, pulser can produce 1 pulse, and then termination of pumping T time, second time turn on pump, in T time, pulser can produce 2 pulses, and then termination of pumping T time, turn on pump for the third time, in T time, pulser can produce 3 pulses, by the pressure sensor (6) on ground reacts pulse signal, digital treating meter (9) can demonstrate pulser actuating signal according to coding protocol, to realize ground and underground equipment two-way communication.
Be described in detail the utility model case study on implementation above, and set forth the concrete case method of detailed description of the invention in actual use procedure, the explanation of above examples of implementation is just for helping the use inclinometer understanding the inventive method; Meanwhile, for one of ordinary skill in the art, according to the thought of the inventive method, all will change in specific embodiments and applications, in sum, this description should not be construed as the restriction used this method invention.
