The Reservoir Accurate Description And Research Of Water Flooding Development In Xindian Field

This article is based on the accurate formation description and establish reservoir mathematical model of this field by the theorical research of reservoir engineering. Then predict water cut and production by history fitting and direct out how to unjust the injection-production system to the field.In this article, by analyzing the development characters of Xindian field, numerical simulation and the predict results of generally unjust means, it fit with the original georgic reserves, original geological pressure of oil area, the actual recovery and water cut very well. This can benefit for numerical simulation. The research can predict that Saertu reservoir of Xindian field is the front surfaces sedimentation of delta and it is different from outer front surfaces of other Saertu reservoir in the west. It is distributed by oil, gas and water vertically in Xindian field and gas reservoir distributes in the seven sedimentation units of the reservoir of S I - GIY. This article also includes the research of the producing reserves of reservoir and calculates the reserve according to monomer-sand. Xindian field has the potential of in filled and out pushed by numerical simulation. It can distribute 6 in-filled wells and 7 out-pushed wells. After the out-pushed wells are finished, the field should take the method of separate zone water injection. There are 5convented injection wells and they are Du3 1-13. Du35-13. Du39-14. Du49-14. 46-14. the oil recovery rate is controlled on 2%. injection-production ratio is 1.2. water intake per unit thickness is 2.6m3/m.d. then the effect of water flood will be very good.
