Oil shale reservoir pore testing significance and method - Database & Sql Blog Articles

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 nanopores of oil shale determine that its specific surface area is very large, about 200m2/g. These micropores and cracks are the storage space for oil and gas.

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.
