摘要
塔中地区下奥陶统发育碳酸盐岩风化壳储集层,为评价这套储集层进行了测井响应特征研究。在研究岩溶风化壳发育的控制因素和分布特征基础上,以成像测井资料为基础结合常规测井在垂向上把岩溶层划分为表生岩溶带、垂直渗流岩溶带和水平潜流岩溶带。通过自然伽马能谱测井识别风化淋滤带,根据双侧向和孔隙度测井资料评价岩溶带的电性和物性特征,建立了不同岩溶带的成像测井特征图版和测井响应特征模式,并进行了岩溶带横向对比研究。
On the basis of research of control factor and distribution characteristic of the karst weathering crust development of Lower Ordovician carbonate rocks in Tazhong area, integrated with conventional well logs, the karst is divided into hypergene karsts, vertical percolation karsts and horizontal underwater current ones. Also, the electric imagine chart and the log response mode are built up using natural gamma ray spectrometry logs, dual laterologs and porosity logs. The lateral correlation study of the karsts in 4 wells is conducted.
