- Abstract:
- For the practice of petroleum exploration, the traditional petroleum geological theory has made great contributions to the development of petroleum industry. But, with the development of petroleum exploration into unconventional petroleum, the traditional petroleum geological theory and insight have come across with many problems and challenges, which can not direct unconventional hydrocarbon exploration effectively. In the perspective of condition of unconventional hydrocarbon accumulation, “source” is not only the rock generating hydrocarbon, but also reservoir and target; tight rock can be effective reservoir; enclosed mechanism of unconventional hydrocarbon is different from the conventional hydrocarbon; continuous and quasi-continuous hydrocarbon accumulation is not controlled by traditional trap condition; detention and short distance migration can form hydrocarbon reservoir; the evaluation methods of storage conditions are not exactly the same as conventional hydrocarbon. In the perspective of hydrocarbon accumulation mechanism, hydrocarbon reservoir can be formed under the mechanism of non-buoyancy in continuous large area; in the perspective of state hydrocarbon occurrence, besides free state, hydrocarbon can be accumulated in the states of adsorption and dissolution; in the perspective of distribution model of hydrocarbon enrichment, except for trap and high point, hydrocarbon can be accumulated in basin sub-sag and slope, sag-wide oil-bearing. The unconventional hydrocarbon resource around the world is more than 4 times of conventional hydrocarbon resource, indicating tremendous exploration prospect.
