摘要

In the condition of high-salinity formation water, it's difficult to identify effectively the typical low resistivity gas-bearing sandstone formation with conventional interpretation method whose characteristics are high shale content, high bound water saturation , low resistivity and low gas saturation. According to the different response mechanism of three porosity curves to the gas-bearing formation, we can identify the low resistivity gas-bearing formation effectively with the porosity ratio method and porosity difference method.
