Reservoir Description Of Bao1 Block Of Keerqin Oil Field

In view of these problems revealed in fine reservoir description of middle-later period in complex fault block, according to the theory and methods of modem sequence stratigraphy, sedimentology, structure geology, hydrocarbon reservoir geology and reservoir engineering, the author make detailed reservoir correlation and also study on aspects of the structural and sedimentary characteristics of reservoir of Jiufutang Formation of Baoyi Oilfield in Liaohe Basin on the base of drilling data, logging data and 3D seismic data. The reservoir heterogeneity and characteristics are studied, and the geological attribute predictive model is also established under dense well pattern. Based on sedimentary microfacies, dynamic analysis and reservoir simulation, the distribution of remaining oil of complex fault block is revealed. In addition, the proposal of adjustment and allocation is also helpful to oilfield production management.Following conclusions are gained through the study on geology status, dynamics, simulation and distribution of remaining oil. The main type of sedimentary facies of Jiufutang is delta under water near bank deposits. The differences between time units influence the macroscopic degree of heterogeneity microcosmic one. On the basis of well data, drilling core and test data, second logging interpretation model of physical property of reservoir have been built. The calculation error of parameters is up to industry standard. In the practice, the model and standard plate have been proved effect.The reservoir is structural litho logic type. The calculation results indicate that the geological reserves is 1651.51×10~4t, oil-bearing area is 6.04km~2. Because of building model in detail and restudy of the parameter, the result is more truthful.The reservoir attribute predictive model is established under dense well pattern by using the method of sequence of guasse. The accurate remaining oil revealed through reservoir simulation.
