一个天然气田的全面开发，应该加大“立体勘探”力度，对气田的新老气藏、气层、可能储层等进行系统认真地分析研究，优选立项并展开作业。通过四川盆地“立体勘探”实践，发现了许多产气层系和层段，资源储备明显增加。在气田内纵向上寻找新的接替层系或层段，重新认识四川盆地“立体勘探”，其基本经验就在于增强地质认识，以科研项目作支撑，技术配套适应勘探新需求，把握好勘探基本原则。“立体勘探” 的新选向研讨，有助于科学决策。

The stereoscopic exploration should be enhanced for the full development of natural gas field, and the reservoir of the gas field should be systematically analyzed.Many gas producing strata and layers are discovered through the stereoscopic exploration in Sichuan Basin, which makes the resources increase.We need to look for new succeeding strata and recognize the stereoscopic exploration for the further exploration in Sichuan Basin. The experience of stereoscopic exploration indicates that we should improve the geological cognition, choose new techniques to meet the exploration requirement and grasp the basic exploration principles.
