Abstract：The connectivity between injection and production wells is significant to adjust and optimize oilfield deve-lopment plans and improve oil recovery. Injection-production connectivity can be analyzed dynamically and statically. The dynamic analysis is based on dynamic data of oilfields, which can directly show the dynamic connectivity between injection and production wells but cannot clarify the distribution of sand bodies between injection and production wells. Static analysis is the basis of reservoir connectivity, but it cannot fully reflect the reservoir changes and connectivity changes during the late injection and production period. Therefore, taking Block A of Xinjiang Oilfield as an example, this paper analyzes the connectivity between injection and production wells by dynamic and static analyses. Firstly, the monthly production report, dynamic fluid level, production and suction profile, tracer, and other dynamic data are analyzed to obtain the dynamic connectivity relations. Secondly, combined with static reservoir lithology, physical properties, and seismic inversion results, the distribution laws of sand bodies between injection and production wells are obtained. Finally, according to connectivity analysis results, geo-logical modeling and numerical simulation are carried out to provide suggestions for hole filling, fracturing, and water plugging. This method can provide a basis for the adjustment of oilfield deve-lopment plans.
