摘要

将千米桥碳酸盐岩古潜山的岩溶发育分为风化壳岩溶和缝洞系岩溶两种成因类型,并论述了两类岩溶的岩石学、矿物学和同位素地球化学鉴别标志。结合勘探和生产成果,阐明了千米桥潜山气藏的天然气分布是受整体构造高点的控制,含气储层受潜山顶面200m左右范围内的风化壳岩溶控制。认为缝洞系岩溶的发育具有明显的期次性,对产层的沟通起着重要的作用。

Abstract

The paleo-harst of Qianmiqiao carbonate buried hill can be divided into two types, the weathering shell harst and the fracture-cavity harst. The paper discussed detailedly the distinguish characteristic of petrology, mineralogy and isotope geochemistry of above types. Combined the results of exploration and development, some points were put forward: a.The distribution of gas trap was controlled by the top of structure; b. The effectual reservoir distributed within about 200 meter to the weathering shell top and was controlled by the weathering shell harst; c. The fracture-cavity harst has obvious periods that was important for connecting productive reservoir.
