WebJan 1, 2024 · The merely meso-pore perforation hole in impervious material has low sound absorption, and the merely micro-pore matrix material has a moderate sound absorption. In contrast, the double porosity material as a combination of the micro-pore matrix and meso-pore perforation hole has a significant enhancement effect on sound absorption. WebJan 15, 2024 · The schematic equivalent circuit and SAC absorption spectrum of the fewer-perforated structure in Fig. 13 (a) show that reducing the number of perforations decreases the resonance frequencies. The peak at about 543 Hz results from the combination of the two close peaks, and has a narrower bandwidth than the originally adjacent peaks together.

Classification of Porosity – Oilfield beginner

WebClassification of Porosity. Pores are classified based on their morphological viewpoint as: Catenary or inter connected pore: This type of pore has more than one throat connected with other pores and extraction of hydrocarbon is relatively easy from such pore, as shown. Interconnected pore. Cul-de-sac or connected or dead end: This type of pore ... WebJan 3, 2024 · Moreover, the perforation design significantly decreases the concentration drop caused by the flooding, as shown in Fig. 7b, as less liquid water blocks the pore space in the assembly and the transport resistance is small. Such optimization is evident when the perforation is located at the liquid water breakthrough point (Case 10). shv34 fastboot https://boldnraw.com
