Sequence Stratigraphy Research About Liushagang Of Easten Of Hainan Fushan Depresssion

Eastern Hainan Fushan Depression is the main field and the white lotus flower district, many years of exploration confirmed that the flow in the region and the flow of three sections of a sand body development, stream Sec sand to mud pack dominated, reservoir is very rich, preliminary studies suggest that flow up and down a sand body can be divided into two sets of reservoir-cap portfolio, work area Of the main parts of the delta front sand bodies - mainly the former delta, the former sand body structure in the work area on the eastern part of the seismic section features clear, but Sand body distribution, reservoir and forming patterns in complex and east and west sides each with a different combination of reservoir and reservoir models. Depression from the perspective of the whole Sequence Stratigraphy starting study series and the correlation frame -work, depositional system and its development model, its purpose is to better division of strat -a, Seismic interpretation, analysis of source direction, and improve forecast accuracy of the reservoir. Collection of well data, including logging, stratification and the number of test oil According, the method of combining the use of well to seismic stratigraphy and correlation series framework, depositional systems and development patterns and characteristics of accum -ulation and total ,Results. Series and sequence stratigraphic correlation framework discussed in detail two third sequence boundary, the initial flooding surface and maximum flooding surface characteristics, and on .Single well stratigraphic sequence and sequence stratigraphic correlation of well; depositional system composition and development patterns, the first composition to determine the deposition of sedimentary systems, and details .Elaborate system of fine sand within the sedimentary facies and dispersion, combined with the sequence of sequence - the sedimentary system tracts distribution system.Sequence stratigraphic framework and depositional systems tracts within the depositional system is a form of sequence stratigraphy of the basic elements. Layer deposition system and deposition of the domain structure .Into a feature sequence determines the composition of different character of the pattern. Of the sedimentary sequence constitutes a pattern of basin depositional systems and facies of the sub- Cloth, in particular within the sequence, reservoir and cap configuration relationships and distribution of prediction is critical.The integrated use of paper sedimentology, sequence stratigraphy, petroleum geology and other disciplines, theories and methods in the study area sequence framework, sedimentary facies, Reservoir conditions, reservoir types were in-depth study, summed up the reservoir characteristics and controlling factors, and points out the direction for further exploration and Profit target area, the Eastern District of Hainan Fushan Depression causes and forecast oil and gas reservoirs have important guiding significance.
