Layered oil production: Background. In view of the current situation that the oil well joint production cannot meet the production needs due to the prominent contradiction between multiple layers and layers, the layer-stuck method is generally adopted for production. The main layer-stuck pipe string structure is as follows: Control layer-production layer. Production layer-control layer. Production layer-control layer-production layer. Through the application of various layer-stuck pipe strings, the problem of inter-layer interference is effectively solved, but the full play of the production capacity of each layer of the oil well is limited. At present, there is an urgent need for a layered co-production technology that can effectively mobilize each contributing oil layer and avoid inter-layer interference, fully tap the production capacity of the oil well, increase the production of the oil well, and improve the development time.
