【 摘 要 】

At present, the A-transition belt water drive has a common foundation, encryption, and four sets of three well networks. The base layer and the encryption layer are very close to each other, and the room for structural adjustment is small. In order to improve the development effect of the encryption layer system, the layer is complemented by the infill hole. This paper expounds the specific practices and effects of layer complementation, through the complementation of layer system to reduce the well spacing and improve the injection and production relationship of narrow river channels, increase the connection direction, and broaden the adjustment space of reservoir and mining structure. It can fundamentally improve the mining and encryption layer mining effects, meet the needs of the development of one or two water flooding development, and achieve better development results by complementing the layers. Block overview; 2. The problem of the encryption layer; 3. The idea of complementing the layers; 4. Evaluation of the practice and effect of layer complementation; 5. Conclusions; References.
