| 摘 要： | 深水浅层钻井过程中可能遇到浅水流、浅层气以及天然气水合物层分解等3种浅层地质灾害（简称＂三浅＂）。要规避这些风险,必须需要开展浅水流、浅层气和天然气水合物成因机理、识别特征及工程危害等方面的研究。国外利用地球物理识别技术和数值模拟方法,结合深水油气钻井测井开展了这方面的研究,在＂三浅＂地质灾害的形成机理和控制因素方面取得了较为重要的研究进展。目前国内学者利用地球物理方法在南海北部深水区LW3-1大气田的周围发现了超压系统、浅层气和天然气水合物。深水水道砂体的发现也推断南海北部深水区具有＂三浅＂地质灾害发育的地质条件。随着深水油气勘探开发的不断深入,评估和预测南海北部深水钻井的＂三浅＂地质灾害十分迫切。

| Abstract: | Shallow water flow,shallow gas and gas hydrate have been encountered in the deep water drilling. In order to predict the geological disasters we need to study the mechanism,identification and engineering dangerous. By using geophysics and numerous modelling,in combination with drilling hole and well logging data,there are great progresses in the‘three shallow＇geological disasters. For the time being,we also found the over pressured system,shallow gas and gas hydrate in the LW3-1 gas field. The discovery of deepwater channel sand indicated that possibility existence of shallow water flow. By the progress of deepwater hydrocarbon exploration and development,it is very important to evaluate and predict the‘three shallow＇geological disasters. |
