The Study Detailed Reservoir In Reservoirs Heidimiao Of Honggang Oilfield

Reservoirs Heidimiao of Honggang oilfield faced some problems in the development process,which include fine structure features of sublayer made clear, the lack of study about deposition microfacies, oil-water interface does not implement. These problems have constrained the effective development of gas reservoirs, To solve these problems, carrying out " The study detailed reservoir in reservoirs Heidimiao of Honggang oilfield ." Geological basis for the provision of oilfield development .Implementation of seismic re-interpretation of structure, reservoir correlation, the study of deposition microfacies ,Application of Logging,we have the following conclusions: 1.Considering the various geological factors which caused bed response, For better reproduction of the advance and retreat lake water evolution, the establishment of isochronous interface layer, The original "top sand mud bottom" of Stratified programs has been adjusted, Adjusted are a prodelta mud deposits at the bottom of sublayer, the delta front at the top of sublayer, the overall performance is the prograde-type sedimentary sequence are composed a number of anti-cyclic sedimentary sequences.2.the study of the area is the layer Heidimiao and the main of deposition is delta front environment, the west side of the area is prodelta environment, Source from the east, northeast, rather than the west, northwest, HI3-HII1 sublayer is the delta frontand prodelta, Including delta front intrafacied can be further subdivided into microfacies types,included underwater distributary channel and mouth bar, sand sheet and so on.3. the main reservoir sand bodies of HI3-HII1 sublayer of Heidimiao is delta front distributary channel and mouth bar sand body,and have the best hydrocarbon.。so well and development program designs should fully consider the type of microfacies factor.。4.Follow the procedure of core coresponding the logging ,then logging mark the seismic data, got minus stucutre and small faults of top Putaohua reservoir with the 3D seismic information.
