Study on the main controlling factors and methods of the lower limit of effective reservoir porosity and permeability in Dengying Formation in Penglai gas area
This project takes the carbonate reservoir of the Dengying Formation in the Penglai gas area as the research object,and uses analytical testing methods such as X-ray diffraction,scanning electron microscopy,cast thin sections,high-pressure mercury injection,and nuclear magnetic resonance to systematically analyze the lithology and physical properties of the reservoir.,pore structure characteristics,on this basis,the reservoirs are classified and evaluated,and the lower limit of the reservoir physical properties is clarified,which provides technical support for reservoir evaluation and reserve scale determination of the Dengying Formation in the Penglai gas area.
