Remote data communication device for well logging debugging

Abstract

The invention relates to the field of oil exploration, and discloses a remote data communication device for well logging debugging, comprising a box body, a circuit board and a display module, wherein the circuit board is arranged in the box body; a display area is formed in the surface of the box body; the display module is arranged on the inner side of the display area; the circuit board comprises a voltage measuring circuit, a current measuring circuit and a CAN communication module; the display module is connected with the circuit board; and the display module is used for displaying the measured voltage value of the voltage measuring circuit and the measured current value of the current measuring circuit. The remote data communication device for well logging debugging provided by the invention is resistant to dust, water and vibration and wide in use environment, and is added with zigbee and FS33 communication modes on the basis of completing the CAN communication protocol, thus the stability and reliability of CAN communication is increased, the wireless connection with a communication target can be achieved, the measurement and display modes of voltage and current can be changed, and the display accuracy of data is improved.

Description

technical field [0001] The invention relates to the field of petroleum exploration, in particular to a remote data communication device for well logging debugging. Background technique [0002] Datadump is an important tool for on-site debugging or code update of products such as petroleum logging instruments LWD (LoggingWhileDrilling,) and MWD (MeasureWhileDrilling). In the prior art, the data download box used for Datadump uses a voltmeter and an ammeter to display voltage information and current information respectively. Often, the voltmeter and ammeter are damaged or the displayed readings are inaccurate, which seriously affects the stability and reliability of the data. , at the same time, the CAN communication function of the existing Datadump is unstable, and it is often impossible to connect to the CAN. The communication protocol is relatively simple, and the data download box of the Datadump must be connected to the logging equipment through a cable. Both situation...

Problems solved by technology

In the prior art, the data download box used for Datadump uses a voltmeter and an ammeter to display voltage information and current information respectively. Often, the voltmeter and ammeter are damaged or the displayed readings are inaccurate, which seriously affects the stability and reliability of the data. At the same time, the CAN communication function of the existing Datadump is unstable, and it often fails to connect to the CAN. The communication protocol is relatively simple, and the data download box of the Datadump must be connected to the logging equipment through a cable. In both cases, the labor cost and time cost are greatly increased for oil well logging commissioning.

[0003] Therefore, the Datadump download box in the prior art cannot meet the requirements of efficient and accurate logging, and it is urgent to develop a new type of remote data communication device for logging debugging
