Meticulous Research For The Subtle Trap Of Reef

Reef is a kind of the special carbonate mass from the organic build-up and the oily sedimentation type in the carbonate sedimentation.It has widely hydrocarbon potentialiy.However,reef hydrocarbon reservoir belongs to the subtle trap which is more difficult for the exploration.Recent years,more geologists have taken studies for the reef, including reef's origin, strucrure,category, diagenesis,delineation of sedimentary facies zones,growth and evolution rule; and have gotten abundance results on the geological area.Some geophysicists had done some exploration for the reef involved the seismic data response.But,there are no more about the distribution and hydrocarbon prediction of local area reefs. Therefore, According to the advantages of multiple-science integration,which are the petroleum geology,palaeotectonics,sedimentology,petrology, geophysics as well as seismic stratigraphy, the author applies rich knowledges which are 3D seismic survey,well logging,drill core analysis, surface outcrop investigation data and previous study documents in that area and more new exploration methods to work on study of reef subtie trap reservoir prediction technology from theoretics to practical application,using 3D seismic data collection , processing,integratical interpretation technology within 3D visualization environment and reservoir prediction technology With more practices, create a set of technical method to give out a more detail description of the reef structure clusters in the Kenjiyak raea of Caspian basin, show out a good petroleum exploration further of reef subtie trap reservoir in this area.Main results of that topic involve below:(1)According to looked through a number of references, the author put forward to discover and predicte the reef subtie trap reservoir using the advace combine geology with geophysics.And it is the first to show out advantages of multiple-science integration on the research of the reef subtie trap reservoir.
