Application of OverDrive software in F block

Reservoir permeability has changed after long-term water injection development in Lamadian oilfield. A large amount of injected water is injected along the high permeability layer and ultra-high permeability layer for a long time, gradually forming inefficient and ineffective circulation, which seriously affects the oilfield development benefit. Therefore, this paper firstly uses the efficient identification and treatment system of invalid circulation field, and selects nine identification parameters to quickly identify invalid circulation well layer in F area. Secondly, through the analysis of the identification results, the macro distribution law of invalid cycle is summarized. Finally, combined with the types of invalid circulation, the corresponding adjustment countermeasures are formulated, and further determine the potential of ineffective circulation well treatment in the block. This study can effectively guide the development effect of water flooding in F zone by carrying out corresponding governance work.
