In recent years, shale gas has gradually been regarded as a non-conventional natural gas resource with great potential. It is one of the most concerned types of energy at present. At present, large-scale exploration and test mining development has been carried out in many places in China.
In March 2012, the four ministries and commissions jointly issued the “12th Five-Year†development plan for shale gas and proposed that the annual output of shale gas in China will reach 6.5 billion cubic meters in 2015, and the annual output will reach 60 billion to 100 billion cubic meters by 2020. Meter.
Oil shale is a special kind of reservoir, which is quite different from ordinary reservoirs. It is generally of ultra-low porosity and low permeability type. The pore structure of oil shale reservoirs is relatively complex, the pore diameter is small, nano-scale pores are generally developed, and a large amount of shale gas is stored in oil shale in an adsorbed state. The presence of nanoscale pores in oil shale makes it important to study the flow of gases in these pores and the governing equations. Nano-oil and gas is an important direction of future geological innovation. Nano-oil and gas are mainly distributed in source rock formations and near-source tight reservoirs in close contact with them, covering shale oil, shale gas, coalbed methane, tight sandstone oil, Tight sandstone gas, tight limestone oil, etc., the pore throat diameter of the reservoir is generally nanometer. The nanopore of the oil shale determines its specific surface area is very large, probably in
Studying and testing the important data such as porosity, pore size distribution and specific surface area of ​​oil shale is of great significance for studying the gas content of oil shale, the occurrence of natural gas and determining whether it has industrial exploration and development value. The 3H-2000PS series automatic surface and aperture analyzer independently developed by Bethes Instrument Technology adopts the static volumetric measurement principle. It has a number of technical patents, and specially designed the sample tube for core testing. The only independent P0 test in China. The instrument is widely used in many research institutes and enterprises including China University of Petroleum, Shanghai University, Beijing Institute of Technology, and Central South University. It is highly praised by customers. 3H-2000PS1 fully automatic surface and aperture The analyzer has high cost performance, high precision and high test efficiency. It is a professional instrument for testing core pore size, pore size distribution and specific surface area. It is very suitable for shale gas, oil rock gas, mud shale, sandstone oil and sandstone gas. The use of scientific research institutions and enterprises such as limestone oil and coal-rock gas has important value for predicting shale gas reservoir reserves.
Bitcoin mining equipment is mainly highly specialized ASIC mill , The maximum computing power of a single miner is 110T/s( Ant S19Pro mill ), The scale of computing power of the whole network is 120EH/s above . Ethereum's mining equipment is mainly graphics card mining machine , Professional ASIC Mining machines are very few , On the one hand, it is because of the of Ethereum mining algorithm [ resist ASIC sex " Improved R & D efficiency ASIC The threshold of the miner , So how much do you know about the mainstream Ethereum mining machine ?
Ethereum mining algorithm has higher requirements for memory , The purpose of this design limits ASIC The use of chips in Ethereum mining . From the results , Most Ethereum mining machines are graphics card machines , This reflects the application of Ethereum mining algorithm ASIC Success on . From the absolute value of computational power scale , The computing power of Ethereum is about 200TH/s, The computing power of bitcoin is about 120EH/s, The latter is close to the former 60 ten thousandfold .
ASIC Mining machines have high computing power , Large power consumption , Like the latest ant S19Pro mill , Rated power consumption is 3250W, Need to consume... Every day 78 Degree electricity , According to the current currency price and 0.23 The electricity price in wet season is RMB , The proportion of electricity charge is 30.68%. Other older bitcoins ASIC mill , Like ants T17 series , The proportion of electricity charges generally exceeds 50%. by comparison , The power consumption of the graphics card miner is low , The proportion of electricity is also low . such as 5600XT8 Graphics card miner of card .
Ant S19-95T It adopts aluminum alloy profile electromechanical integrated design , Parallel four fan structure . According to the measured data , In line with and better than the official data .S19 The series is provided by TSMC 7nm chip , A new generation of customized chips with perfect whole machine architecture and high conversion rate APW12 Power Supply , Reduce power loss during conversion , Use more energy-saving , Greatly shorten the return cycle of the miner . In addition, the newly upgraded mining machine operation interface is also more humanized , Real time computing power . The average computing power and the operation of each chip are clear at a glance .
Shenma mining machine M30S-86T/88T/90T, Bit micro 2020 Launched in 2013 M30S Series of new mining machines , Announced that it would M30S The series is expanded to three 3X product . stay 3X In the new standard , Bit micro promises a one-year warranty for its series of products . This series of mining machines are provided by Samsung 8nm chip , Among them, god horse M30S series , The power consumption is 38J/T, Provide higher computing power , Lower power consumption and high stability.
