摘要:

天津地区蓟县系雾迷山组热储层岩性以碳酸盐岩为主,是天津地区目前开采层最深、开采强度最大、流体温度最高的主力开采层。钻遇该层的所有地热井均能开采出地热流体,反映了该热储层在区域上具有相对均一的发育特征。但通过钻探、井下物探及流体特征分析发现,因岩性不同、结构差异以及外部条件的变化,如溶蚀、构造、风化等多种因素对岩石裂隙改造的程度不同,导致不同构造部位、不同埋深的岩溶发育特征有较大差异,从而将岩溶分为裂隙型和裂隙孔隙型两大类。了解和掌握雾迷山组热储层深部岩溶发育特征,对天津地区地热资源勘查、开发和评价都具有十分重要的意义。

Abstract:

The Wumishan reservoir, main carbonate rock, is the main exploration reservoir with the deepest depth, the largest quantity and the highest fluid temperature. All geothermal wells of Wumishan have geothermal fluids,which shows that the reservoir has the relative homogeneous characteristics in the study region. The analysis of drilling, geophysical prospecting and fluid characteristics reveal that, lithologic difference, textural discrepancy and the changes of exogenous conditions, such as corrosion, structure and weathering, engender different rock fractures, thus, the very large different growth characteristics  of karst occur in the different structure positions and depths. Reservoirs are classfied into two kinds as follows,fracture  karst  and fracture porosity  karst.  It is very important for the exploration, development and evaluation of geothermal resources in Tianjin to comprehend and hold the characteristics of karst in  Wumishan reservoir.

Key words: Wumishan reservoir, karst structure, drilling, inhomogeneity, Tianjin
