摘要
尔多斯盆地长庆气田中区马五１４储层分为气层、低产水层、中高产纯水层、气水同层、干层五种产层类型，建立了相对应的测井综合判识标准。剖析了马五１４气藏的成藏条件，认为燕山中期的构造运动系天然气运移聚集的转折点，后期天然气由西向东运移而聚集在上倾方向致密遮挡带下的圈闭内。研究了马五１４储层气、水分布特征及天然气富集规律。
The M5 1 4 reservoir is divided into gas beds, water beds with less production, water beds with higher production , water and gas beds and dry beds. A comprehensive logging identification criterion is established. The reservior forming conditions are analyzed. The key time of gas migration and accumulation was followed after the tectonic middle Yanshan activity had occurred. The gas migrated from west to east and accumulated in traps which were sealed by the up dipping tight zones. The principle of gas accumulation and the distribution characleristics of water and gas are specified in detail in this paper.
