Fig. 1 is the schematic block diagram of the composition of the ambient parameter measurement pipe nipple of the present invention.
Detailed description of the invention
The ambient parameter of the present invention measures the component parts that pipe nipple is high speed the spread of the rumours logging instrument, and the ambient parameter with independent completion measures function, can independently manufacture, keeps in repair and debug, and needs and high speed the spread of the rumours logging instrument combines use.The ambient parameter being combined with the present invention measures high speed the spread of the rumours logging instrument of pipe nipple, by its distinctive instrument internal data/address bus and communication protocol, carries out data transmission between each composition functional module.
The data/address bus of above-mentioned high speed the spread of the rumours logging instrument, such as and carries out the transmitting-receiving of data and order between ambient parameter measurement pipe nipple, cable end voltage detection module, GR measurement pipe nipple etc..Furthermore it is also possible to have an external data bus, it is to realize carrying out data and the bus of order forwarding in high speed the spread of the rumours logging instrument and instrument string between other instruments.Two data buses are non-interference, and unique common factor is exactly high speed the spread of the rumours system (i.e. down-hole gateway), and the data that all of down-hole gathers are required to be aggregated into high speed the spread of the rumours system of high speed the spread of the rumours logging instrument and forward.
Hereinafter, referring to the drawings the ambient parameter measurement pipe nipple of the present invention is illustrated.
Fig. 1 is the schematic block diagram of the composition of the ambient parameter measurement pipe nipple of the present invention.
Have as it is shown in figure 1, the ambient parameter of the present invention measures pipe nipple 100: sensor 110, it includes a pressure transducer 111, temperature sensor 112 and resistivity sensor 113；Open pressure pretreatment circuit 121；Temperature pre-treatment circuit 122；Resistivity pretreatment circuit 123；Signal electrode drive circuit 124；AD sampling module 131；DAC(digital to analog converter) 132；FPGA(field programmable gate array) 140, it includes AD(digital-to-analogue) the AD control module that sampling module 131 is controlled, the sampled data cache module that sampled data is cached, electrode drive signal generator 143, the DA control module that DAC132 is controlled, control module and for storing the data memory module of data；And DSP(digital signal processor) 150, including control module, number bus 152, digital phase sensitivity detection module 153, temperature tension force processing module 154 and data read module.
After pressure transducer 111 is provided power supply, a corresponding pressure voltage signal is exported a pressure pretreatment circuit 121, after low-pass filtering through pressure pretreatment circuit 121 etc. process, then via AD sampling module 131 and pass to the temperature tension force processing module 154 of DSP150 by FPGA140 and carry out data process.
After temperature sensor 112 is provided power supply, corresponding temperature signal is exported Temperature pre-treatment circuit 122, after low-pass filtering through Temperature pre-treatment circuit 122 etc. process, then via AD sampling module 131 and pass to the temperature tension force processing module 154 of DSP150 by FPGA140 and carry out data process.
