Application of Gas Logging to Natural Gas Hydrate Prognosis in Sanlutian of Muli,Qinghai
摘要
Abstract
With the advantages of sensitive and quick monitoring hydrocarbon gases in different stratigraphies, gas logging has become a mature technology for exploring the conventional or unconventional oil and gas.Con-sidering that while the drilling tool is grinding strata bearing gas hydrate,the gas hydrate could decompose and release numbers of hydrocarbon gases which can be sensitively monitored by gas logging,this paper tries to dis-cuss and establish a real-time prognosis method to recognize gas hydrates in permafrost regions in Muli of Qing-hai.Taking drillhole DK8-19 in Sanlutian coal field in Muli of Qinghai as an example,the application,prob-lems and suggestions of this real-time prognosis through gas logging was discussed.The practical application shows that the goodness of fit between the result of singly using gas logging and that of combining geological analysis and testing is up to 85.71%,and the result of combining gas logging,geological analysis and testing will be better.关键词
