Geophysical exploration technology. Applications in lithological and stratigraphic reservoirs / Технология геофизических исследований. Применение в литологических и стратиграфических коллекторах

In China, oil and gas resources mainly accumulated in the Mesozoic and Cenozoic continental basins, and the proven reserves of oil and gas in continental basins account for three-quarters and nearly half of China’s total reserves, respectively (Zhai, 1996). Almost 95% of the proven oil reserves in China are concentrated in continental basins (Dai, 2000). After more than half a century of exploration, a large number of structural reservoirs and some lithological and stratigraphic reservoirs were discovered in continental basins. Although the exploration efforts of many Mesozoic and Cenozoic basins has been relatively high, especially for eastern basins, there is still a great potential for the exploration of lithological and stratigraphic reservoirs. In order to promote petroleum exploration development, we must develop new technologies and methods, and strengthen the basic research theories targeting lithological and stratigraphic reservoirs, using petroleum geological characteristics of continental basins (Jia, 2003). <...>
