One of the most important activities in the petroleum reservoir development and management process is the historical matching process. Matched models are fundamental to making reliable future predictions possible and provide insight into the level of understanding of geological and reservoir models. Depending on the production data available in the field and the complexity of a reservoir, the historical matching process can be time-consuming. To obtain a suitable model, some modifications can be made to the geological and reservoir models, mainly in attributes with greater uncertainty, e.g. relative permeability curves, its distribution across the reservoir and other parameters with little uncertainty. 'samples. One of the objectives of this work is to perform historical matching on the Zhaozhouqiao oil field, specifically Block Zh86, using Schlumberger's Petrel-RE 2014 simulation software. Historical matching will be done based on trial and error by modifying some reservoir properties, scaling the end point, and modeling and including the aquifer. support in the system. The best historical match was achieved by changing the critical water saturation (SWCR) in the system, modeling aquifer media using the Carter Tracy Aquifer model, and changing the model's horizontal and vertical permeabilities. Once the historical match is obtained, two prediction strategies are developed and compared, where we performed forward modeling to establish a certain level of confidence in the reservoir model. Production indices; Water reduction, water production, oil production and oil rate of wells and the field as a whole were planned. Index results were presented over time and analyzed. The results show that block Zh86 of Zhaozhouqiao oil field is still very promising in terms of production. An uncertainty and sensitivity assessment was performed on the reservoir model to analyze the impact of certain reservoir properties on volume calculations and simulation results in the Zh86 block reservoir. model. The impact of the uncertainty in our SW and contact positions on the volume calculations in this model is visible. Keep in mind: this is just a sample.

Using a model with fine grid resolution allows the well to be placed.
