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.

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

Above, 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 fully automatic surface area and aperture 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, and is very suitable for shale gas, oil rock gas and mud page. Rock, sandstone oil, sandstone gas, limestone oil, coal-rock gas and other scientific research institutions and enterprises use it, which has important value for predicting shale gas reservoir reserves.
