The distribution, the status of exploration and exploitation as well as the reservoir geological characteristics and formation mechanism of low-permeability oil and gas resources were systematically investigated. The main affecting factors of the low\|permeability oil and gas resources are as follows: not easy to identify oil and gas reservoirs, difficult identification of oil and gas layer, low permeability, starting pressure gradient, small elastic energy, slow effectiveness of water injection wells, significant decrease in liquid water production index after water breakthrough, serious water channeling and flooding. Multi\|parameter joint inversion of reservoir prediction technology, fracturing technology, well optimization technologies, advanced water technology, horizontal wells technology, CO2 miscible flooding techniques, microbial enhanced oil recovery technology are special technologies for exploration and exploitation of low\|permeability oil and gas resources.
