Abstract: In the Dagang region, the Ordovician is 600 ~ 800 m thick and mainIy consists of Iimestones and doIostones. Karst reservoirs are deveIoped. The main controIs on karst reservoirs are ：IithoIogy, depositionaI environments, hydroIogy, an- cient Iandform, fractures and weathering time and so on. The IithoIogy composed of doIostones and gypsum is favorabIe for the deveIopment of karst reservoirs. TidaI fIat environments are favorabIe facies to deveIop karst reservoirs. Karst reservoirs are mainIy deveIoped 20 to 200 m beneath the unconformity. Beofore the Carboniferous, the Iand surface of the study area incIined from southwest to northeast, and the ground water fIew from southwest to northeast. Karst reservoir beIt formed in this time aIso trends southwest-northeast. The karst sIope and karst depression with no standing water are favorabIe for the karst reservoir deveIopment, especiaIIy the karst sIope. Karst reservoirs tend to deveIop in the pIace where fractures and fauIts are abundant, and the trend of fractures and fauIts controIs the trend of karst reservoir beIts The Ionger the weathering time, the better the karst wiIIbe deveIoped.
