Two key technologies about exploration of stratigraphic/lithological reservoirs

Stratigraphic/lithologic traps play a very important role in reserves and production increase in Chinese onshore exploration. It is practically proved that the key exploration technologies are reservoir prediction and sequence stratigraphy. Generally, reservoir predicting technologies can be classified as: recurrence inversion, logging restriction inversion and pre-stack inversion, which should be fit to some conditions in application. To raise vertical resolution, reservoir feature reconstruction is an effective method and seismic attribution interpretation is also very important. The application of sequence stratigraphy is affected by marine sequence framework in Chinese petroleum plays. In the past several decades, continental sequence stratigraphy didn't industrialize through the combination of outcrop, drilling and logging. So six industrialization steps for sequence stratigraphy could be effectively presented in practical exploration.
