| 摘 要： | 在川西地区浅层油气勘探开发过程中,已总结出地震“低频、强振幅”油气预测模式,并早已应用于勘探中。随着该区勘探开发程度的提高,该模式作为已成熟的油气预测方法在一些地区出现了预测失误。这里经分析了地震“低频、强振幅”的形成机理后总结出了模式预测中典型的“陷井”,并提出了降低模式预测风险的附加条件。

| Abstract: | 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. |
