Unconventional Gas Geological Evaluation Test Research

As the global economic growthing, the contradiction of the energy consumption and demand is becoming more and more obvious. Today the content of the traditional energy is fewer and fewer, alternative energy has also been put on the agenda. The important position of the unconventional gas gets the attention of each country, but its exploitation in the difficulty and cost of mining becoming more and more obvious. And the research of the unconventional gas geological property becoming more and more obvious. As the rapid development of the econmy and science and technology, people’s living standard is improving. The traditonal drainage gas gathering menthod wasting time and energy,people also pursuit of a more superior and comfortable life.This work mainly in the following areas:1) The hardware design of measuring device includes mechanical hardware design and the hardware design of circuit.Mechanical design including test system, the most important is choicing the GAS mass flow meter is the key work of the Mechanical hardware design. Gas mass flowmeter is directly related to the accuracy requirement of experimental device, and also provide the signal to the single-chip microcomputer, related to the success of the whole, so the flowmeter selection is very important. The hardware design of the circuit is mainly vibration sensor conditioning circuit design, and microcontroller data acquisition and processing circuit design. Eventually we can be able to improve the anti-interference of the board and reduce its power consumption in fulfilling its functions.2) Measuring device software design, it include data acquisition A/D conversion process design, data storage program design, research phase of MCU and PC-communication program design, as well as LCD display module program design.3) PC-assisted treatment program design. Because the design of the device needs to be based on a large number of experiments, so for the convenience of experiments, saving test time, at the research stage we need the help of PC-power. PC-programming processing software is NI’s Lab VIEW. We need to achieve program design of data transfer between the PC and the slave, as well as digital processing of signals collected, mainly the value of the signal feature extraction.A high-accuracy of gas content automatic sizing device was designed to detectde the signal data of the gas volume, and the signal data was proportional to the gas volume. A high-speed serial A/D converter MCP3202was used to convert the analog signal to digital signal. A single chip microprocessor STC12C5410AD saves the data to its exteral RAM. STC12C5410AD can be programmed with serial port and integral the data during the bleeding process in every time. The MCU computes and analyzes the sample data, and save the result to the EEPROM memory.
