【摘要】 古岩溶发育过程中的塌陷是一种普遍现象,其形成的古岩溶塌陷体是重要的油气储集体。借鉴现代岩溶塌陷的成因机理,归纳了古岩溶塌陷与现代岩溶塌陷的相似之处,并从形成机理、联合塌陷体的成因及其储集意义等方面梳理了古岩溶塌陷的成因特点。对于古岩溶塌陷体,可通过钻井、岩心、探地雷达、地震、常规测井和FMI成像测井等技术手段来识别、研究。由于不同地质背景下古岩溶塌陷体发育模式不尽相同,使得研究过程中存在诸多问题。针对这些问题,提出了下一步亟待开展的3点工作建议。更多还原

【Abstract】 In the development and evolution of the paleokarst,the collapse of paleocave is a common phenomenon,and the collapsed-paleocave systems are good oil / gas reservoirs. Based on the formation mechanism of karst collapse,this paper illustrates the similarity of paleokarst collapse and karst collapse,then combs the genesis characteristics combined with the formation mechanism and the cause of coalesced collapsed-paleocave systems as high quality reservoirs. The collapsed-paleocave systems can be studied on the basis of characteristics of well drilling,cores,ground penetrating radar,seismic interpretation,conventional logging and FMI imaging logging.As the patterns of collapsed-paleocave systems vary in different geological settings,many problems remain to be resolved. To solve these problems,this paper put forward three proposals that are to be carried out urgently.更多还原
