Sandstone reservoir micro-pore analysis system based on geological causes

Abstract

The invention discloses a sandstone reservoir micro-pore analysis system based on geological causes. The systemcomprises a rock stratum analysis unit, a sound wave analysis unit, an information analysis unit, a pore permeability test unit and an information storage library unit, and is characterized in that the rock stratum analysis unit is in communication connection with the information analysis unit; the sound wave analysis unit is in communication connection with the information analysis unit, the information analysis unit is in communication connection with the information storage library unit, and the pore permeability test unit is in communication connection with the information analysis unit. According to the present invention, information comparison is carried out through the rock stratum analysis unit and according to the local geological causes, the speed of obtaining the information, such as the characteristics, the structure and the configuration relation of the rock stratum, etc., is increased, the information obtaining difficulty is reduced, and the manpower and material resources are saved.

Description

technical field [0001] The invention relates to the field of geological analysis, in particular to an analysis system for microscopic pores of sandstone reservoirs based on geological genesis. Background technique [0002] A rock formation that can store and infiltrate fluids is called a reservoir that can store and infiltrate oil and gas. It must have a storage space (porosity) and a certain connectivity (permeability) of the storage space. The so-called sandstone reservoir should be the high content of sandstone in its rock. The deep high pressure and low permeability sandstone reservoir belongs to the category of low permeability reservoir, but it is different from the conventional low permeability reservoir. The large changes in formation pressure during reservoir development lead to changes in pore structure and physical properties, which affect the effect of oilfield development. Understanding the microscopic pore-throat characteristics of the reservoir is the key to ...
