Description

Technical field:

[0001] The invention relates to a method for oil-gas exploration and development well oil-gas-water layer interpretation, in particular to a multi-parameter dimensionality reduction oil-gas-water layer identification method. Background technique:

[0002] For a long time, the oil industry has widely used electrical logging and mud logging data to explain oil and gas layers in the exploration and development of oil fields, which has played a vital role in the oil industry. In the long-term scientific research and production practice, according to the characteristics of oil fields from exploration to development in different stages, many methods have been formed, and many oil and gas layers have been explained according to the characteristics of oil and gas layers with high resistivity and high acoustic time difference. confirmed. However, with the continuous deepening of oil and gas exploration, the target geological conditions of exploration and development...
