摘要
在总结和分析451口井地层水测试资料的基础上,对蜀南地区茅口组地层水矿化度和水型特征进行研究,结合钻井、地震、测井等资料,系统总结了古岩溶的垂向分带模式,阐述了各岩溶带在剖面上的发育特征,并对不同化学性质的地层水的储存方式进行了分析。结果表明:该区地层水矿化度普遍较低,变化范围大,矿化度分布特征与地层水势能有关。CaCl2型地层水矿化度较高,具正向浓缩、深变质、渗流缓慢等特征,NaHCO3型、Na2SO4型、MgCl2型水矿化度较低,其出现与岩溶作用有关,所在地区的地层水性质不活跃。古岩溶带在垂向上可分为:表层岩溶带、垂直渗流岩溶带、水平径流岩溶带和深部潜流岩溶带,不同岩溶带特征各异。CaCl2型水的形成与大气淡水淋滤、地层压实释水和埋藏变质作用有关,以深层滞留水方式赋存于地层孔隙中,低矿化度水则以封存水方式储存于岩溶封闭体中。
Based on a summary and analysis of the analytical data of the formation water in 451 wells,the authors studied the characteristics of the salinity and types of the formation water of Maokou Formation in Shunan area.In combination with the drilling,seismic and logging data,this paper has systematically summarized the vertical zonal mode of the paleokarst,elaborated the development features of various karst zones along the profile,and analyzed the storage styles of the formation waters with different chemical properties.The result shows that the salinity of the formation water is on the whole relatively low with a large variation range and that the distribution of the salinity is connected with the potential energy.CaCl2-type formation water is of high salinity,positive condensation,high metamorphism and slow seepage.NaHCO3-type water,Na2SO4-type water and MgCl2-type water have low salinity,their existence is related to karstification,and the place of their distribution is of negative water property.The paleokarst system can be divided into four vertical sections: surface karst zone,vertical infiltration karst zone,horizontal runoff karst zone and deep underflow karst zone,with each zone having its own features.The generation of CaCl2-type formation water is related to such factors as the leaching of atmospheric water,the releasing of compaction water,and the burial metamorphism.Such formation water is stored in pores in the form of deep resident water while the low-salinity water is kept in the karst closed system in the form of burial water.
