| Abstract: | ??Carbonate rock palaeokarst is closely related to oil-gas,and the karst vugs are the important places of oil-gas enrichment. Besides understanding the factors of palaeokarst burial location,genesis etc.,the relation between palaeokarst vug distribution and palaeokarst types must be known to find the oil-gas reservoirs relative to palaeokarst.Through studying karst rocks statum occurrence and rock consolidated degree when developing,carbonate rock palaeokarst is divided into horizontal palaeokarst and fold palaeokarst;furthermore,in the light of karst patterns,it is divided into 4 types such as horizontal limestone karst, horizontal dolomite karst,fold limestone karst and fold dolomite karst.In order to probe the characteristics and distributive laws of the various karst reservoirs, based on discussing palaeoclimate, palaeogeomorphology,lithology,palaeolopographic structure etc.controlling palaeokarst reservoir development and according to the characteristics and main control factors of the various palaeokarst types,4 modes of palaeokarst reservoir distribution are summarized.The vug development patterns,characteristics and distributive laws of the various karst modes are expounded by examples. |
