| 摘 要： | 雄安新区蓟县系雾迷山组中赋存丰富的地热资源,研究雾迷山组岩溶热储特征及优质储集层发育的主控因素是地热资源勘探的基础。综合运用野外剖面、岩心、薄片、钻井、测井、录井等地质与地球物理资料,对雾迷山组岩溶热储特征和演化过程进行了深入研究,明确了优质储集层形成的控制因素,预测了有利靶区。结果表明,雾迷山组岩溶热储主要岩性为晶粒白云岩、颗粒白云岩、微生物白云岩、硅质白云岩和角砾白云岩等,溶蚀孔洞、裂缝及其组合为主要的储集空间类型。雾迷山组热储平均孔隙度为3.18%,平均渗透率为91.48×10-3 μm2;其中角砾白云岩物性最好。雾迷山组岩溶热储经历了沉积—准同生期成孔(雾迷山沉积期)、Ⅰ期表生增孔(雾迷山沉积期后至青白口纪前)、Ⅰ期埋藏减孔(青白口纪前至三叠纪)、Ⅱ期表生增孔(三叠纪—古近纪)、Ⅱ期埋藏减孔(新近纪—第四纪)5个阶段,岩性及岩相、成岩作用和构造应力是雾迷山组有利热储形成的主控因素。藻云坪—云坪相、表生岩溶、埋藏溶蚀、准同生岩溶、岩溶高地—斜坡和地层裂缝段比率大于0.4的6项叠合区是研究区最有利的岩溶热储发育区。

| Abstract: | There are abundant geothermal resources in the Jixianian Wumishan Formation of Xiong’an New Area. To study the characteristics and main controlling factors of high-quality karstic geothermal reservoirs in the Wumishan Formation is the basis of the exploration of geothermal resources. The geological and geophysical data, including outcrops,cores,thin sections,drilling and logging,are utilized to study of the characteristics and evolution process of karstic geothermal reservoirs in the Wumishan Formation. The aim of this article is to clarify the controlling factors of formation and development of high-quality geothermal reservoirs,and to predict the favorable target areas. The results indicate that the main lithologies of the karstic geothermal reservoirs in the Wumishan Formation are grain dolomite,granular dolomite,microbial dolomite,siliceous dolomite and breccia dolomite. The main reservoir spaces are caves,vuggy pores and fractures. The average porosity of the geothermal reservoirs in the Wumishan Formation is 3.18%,and the average permeability is 91.48 ×10-3μm2 . Among them,the breccia has the best petrophysical properties. The karstic geothermal reservoirs of the Wumishan Formation mainly experienced five stages of evolution including sedimentation-penecontemporaneous pore formation(Jxw),epigenic karstic stage Ⅰ(after Jxw-before Qb),burial stage Ⅰ(before Qb-T),epigenic karstic stage Ⅱ(T-E)and burial stageII(N-Q).The lithologies and lithofacies,diagenesis and tectonic stress are the main controlling factors for the formation of favorable karstic geothermal reservoirs in the Wumishan Formation. The most potential areas of the karstic geothermal reservoirs in the study area are located at regions characterized as the algal dolomitic flat-dolomitic flat,the epigenic karst,the buried karst,the penecontemporaneous karst,the karst platform-slope and the thickness ratio between fractures and the Wumishan Formation larger than 0.4. |
