地质勘探

Burial dolomitization is a critical model of dolostone reservoir genesis. Many issues involved in dolomitization diagenetic system, such as thermal fluid origin and its metasomatism process of burial dolomitization, later dissolution period and its process characteristics, have become the difficulties and frontier areas both for petroleum exploration and for scientific research in marine carbonate rock fields.
