Distribution of Clastic Karst Reservoirs of the Paleogene Dongying Formation in the Jidong Laoyemiao Oil Field
摘要
Abstract
Carbonate karst reservoir is very common, but no reports on clastic karst reservoir. The clastic karst reservoirs have been discovered in the Paleogene Dongying Formation in the Jidong Laoyemiao oil field in this study. The distribution and control factors of the clastic karst reservoir are very similar to those of the carbonate karst reservoir. The sedimentary facies of sandstone reservoir of the Dongying Formation is delta. Within sandstone reservoir, calcareous cementation is widespread. Based on the core and log data analysis, sandstone karst reservoir developed in a zone of 150 m in thickness below an unconformity between the Neogene and Paleogene strata. The porosity of the sandstone karst reservoir is mainly produced by the dissolution of calcareous cements. We suggest that a zone below unconformity is favorable to reservoir development for calcareous sandstone.关键词
