Current status and progress in research of hydrocarbon cap rocks
摘要
Abstract
It was reviewed in this paper the history and current status of the research of hydrocarbon cap rocks. The research progress in both mud and evaporite cap rocks was summarized, and the current research status of dynamic sealing mechanism was analyzed. There are 5 stages in the research development of cap rocks, and the focus of research has shifted from rock physics to deformation process and sealing effectiveness during hydrocarbon accumulation, such as study in high quality seals, mechanical properties of cap rocks, matching between sealing capacity and accumulation conditions, and so on. Extensive literature review suggests that evaporites are very important hydrocarbon seals all over the world and karstification in later stages would affect the sealing capacity; sedimentary texture, structure, and composition (especially clay content) of the mud rocks show fairly important influencees on sealing capacity of mud rock seals; deeply buried mud rocks which have been through high diagenetic evolution still show excellent sealing capacity. Capillary physical sealing, overpressure sealing, capillary multiphase sealing and several other types of sealing mechanism have been discovered and studied, but the capillary physical sealing is the most fundamental sealing mechanism. Counties that are active in cap rock research include the United States of America, Norway, Austrialia, Britain, Italy, Germany, and so on. Institutions involved are mainly colleges and universities, goverment institutions, and petroleum companies.关键词
