深盆气藏为一种主要发育在碎屑岩致密储层中的非常规气藏 ,产气储层的基本特性是低孔隙度、低渗透率、高含水饱和度以及异常 (低 )地层流体压力等 .这些特点的存在使得深盆气藏的地质开发具有很多特殊性 ,以地质分析为基础 ,结合钻井工程和开发工艺等进行全面分析 ,最终目的是降低生产成本 ,提高开发效益 .对深盆气藏地质开发的多种技术进行了简单讨论 .深盆气藏的主要开发目标是其中的甜点、黄油层以及与其相邻发育的共、次生油气成藏组合 ,井位部署需要仔细的地质资料分析 ,储层保护需要特殊的钻井技术 ,产量提高需要有效地增产措施 .因此 ,深盆气藏的开发需要综合配套技术 .
Deep-basin gas reservoirs are unconventional gas reservoirs mainly developed in clastic tight reservoirs. The basic characteristics of gas-producing reservoirs are low porosity, low permeability, high water saturation and abnormal (low) formation fluid Pressure, etc. The existence of these characteristics makes the geologic development of deep basin gas reservoirs have many particularities, and based on geological analysis, combined with drilling engineering and development process, the ultimate goal is to reduce production costs and improve development benefits. A brief discussion is made on a number of techniques for the geologic development of basin gas reservoirs. The major development targets for deep basin gas reservoirs are the desserts, the butter layer, and the secondary and secondary hydrocarbon accumulation combinations developed adjacent to it, which require careful Geological data analysis and reservoir protection require special drilling technology, and the yield increase needs effective stimulation measures. Therefore, the development of deep basin gas reservoirs needs comprehensive supporting technologies.
