THE MECHANISM AND TRAP OF "LOW FREQUENCY AND HIGH AMPLITUDE" ON SHALLOW GAS SA NDSTONE IN WESTERN SICHUAN
LI Jia-pen · Computing Techniques for Geophysical and Geochemical Exploration · 2003
The oil and gas forecast model--low frequency and high amplitude o n shallow gas sandstone in western Sichuan has been summarized and applied in e xploration and development for a long time and performed many successful case s. Following the target deepen of exploration and development, the model had, however, shown some misplays in some regions. The paper puts forward the additi onal conditions to reduce the forecast risk based upon analyzing the mechanism o f low frequency and high amplitude and summing up the typical traps of the fo recast model.
