建南气田石炭系气藏地质特征及潜力分析

建南气田石炭系气藏为一具有边水的地层一构造复合气藏，气层分布稳定，是以细粉晶云岩和角砾云岩为主的微裂缝一溶孔型储层。通过对石炭系气藏地质研究，结合各生产井生产情况，认为黄龙组储层尚有一定扩边潜力，在储量范围内、井控面积外，尚可进一步部署井位外扩探边。

Geologic Feature and Capability Analysis of Gas Reservoir of Carboniferous System in Jiannan Gas Field

. Gas reservoir of carboniferous system in Jiannan Gas Field is a layer--structure compounding gas reservoir with edge water, in which gas layer has a stable distribution and belongs to microfractttre--dissolved pore reservoir with fine powder crystal dolomite and breccias as its main members. Through geologic study of gas reservoir of car- boniferous system and according to production status of each producing well, it is believed that the reservoir stratum in Huanglong Formation still has some extension capability, so it is possible to make a further plan for well--site ex- ternal expansion delineation within the scope of reserves as well as outside well control area.
