Evaluation of Water Injection Development Effect in Yan10 Reservoir in A Oil Region of Wuqi Oilfield
The Yan10 oil reservoir in A oil region of Wuqi oilfield started water injection development in 2018,and the main layer was Yan101-1.The edge+point shaped water injection well network was adopted,and the natural decline rate of the oil region decreased obviously after water injection development.However,the heterogeneity of the Yan10 oil reservoir plane was highly,causing uneven water line advancement after water injection,and some oil wells had a fast increase in water content.Therefore,it is necessary to evaluate the effectiveness of oilfield water injection development for providing a basis for comprehensive management.
