Fine Reservoir Description Of Ng3-4 In Bo89 Block Of Gudao Oilfield

For Bo89 Block of Gudao Oilfield Ng3-4 to carry out stratigraphic correlation, down to the deposition time units. On this basis, combined with the implementation of well-seismic fault system, description of each deposition time unit body structure forms the top surface of the sand. Starting from coring wells, reservoir characteristics according to research carried out by a point to the line of research ideas and then to the surface, describing reservoir heterogeneity. Comprehensive logging, testing, production test and other information, to develop a standard electric water sentenced to identify, describe water distribution, estimating reserves. On the basis of these studies, and reservoir development combined with the establishment of a three-dimensional fine geological model for the numerical simulation research and development programs adjusted basis.Bo89 Block of the Gudao Oilfield Ng3-4 can be divided into nine small vertical layer 11 deposition time unit, East West overall structural configuration, each developmental East and West boundary of a fault. Reservoir having a longitudinal multi- layer, thin, flat dramatic changes, strong heterogeneity, a strong sensitivity characteristics. Each unit has a separate deposition time water systems, oil distribution in the high parts of the structure, reservoir depth of 1190 ~ 1270 m, reservoir lithology type genus- a layered structure common oil reservoir, geological reserves of 469×104t.
