摘要:

利用露头、钻井及岩心等资料,以地球化学、储层、气体成因以及构造保存条件等为重点研究对象,对湖南省常德地区牛蹄塘组页岩气的成藏条件开展了系统分析。研究表明:该区域牛蹄塘组富有机质页岩具有机碳含量高、厚度大、热演化程度普遍较高的特点;页岩的有效孔隙度为2%~5%,储集空间主要以基质孔隙为主,朗格缪尔体积分布于1~3.5m 3/t之间;盖层厚度较大(>200m),具备形成页岩气的生、储、盖条件。分析了常德1井产水产气的原因,指出所产气、水主要产自牛蹄塘组底部富有机质页岩中的封闭裂缝体系中,处于地层水交替阻滞带,所产烃类气体主要为原油裂解气,非烃类气体主要为过成熟阶段产物,并混入了部分大气,氦气为壳源无机成因。明确了常德地区页岩气成藏过程及散失模式,认为构造破坏、地层水散失和扩散作用是页岩气散失的主要途径,页岩的含气性主要受构造及保存条件控制。优选常德1井以西(地层水交替阻滞带以下)保存条件较好的区域为页岩气分布的有利区,具有较大的资源潜力。

Abstract:

Based on the geochemistry,reservoir,origin of gas and structure preserving condition,we systematically discuss the accumulation condition of Changde Niutitang shale by using outcrops,drilling and core data.The organic rich shale of Niutitang Formation has good hydrocarbon generation conditions which are characterized by high TOC,great thickness and high thermal evolution degree,good reservoir conditions characterized by 2%-5% effective porosity and high maximum adsorption capacity (1-3.5m 3/t) whose main storage space of organic rich shale is the matrix pore and thick cap rocks (>200m).It has founded out the reason why Changde 1 well produces both gas and water and established the producing gas and water model.The gas and water is mainly from the fractures of Niutitang organic rich shale in the obstructive replacing zone and the gas is a mixture of the gas generating from shale in over mature stage and the air,and may have some deep source gas.We preliminarily analyzes the shale gas accumulation process and dissipation model,and makes clear the main gas content influence factors of organic rich shale of Niutitang Formation are the tectonic movement and the preservation condition and the diffusion of gas is also an important factor.We optimized the west part of well Changde 1 which has great resource potential as the promising exploration target due to good preservation condition for shale gas.

Key words: Changde area, Shale gas, Accumulation process, Influence factors, Dissipation model, Gas-bearing properties
