Abstract
Volume fracturing is an effective means to improve the development effect of low permeability tight reservoir. While forming one or more main fractures, natural fractures can be continuously expanded to realize the communication between natural fractures and rock bedding and improve the reconstruction effect. In this paper, according to the characteristics of low permeability tight reservoir in the second member of Kong2 formation in Dagang area, reservoir characteristics analysis and volume fracturing process parameters were carried out, and key fracturing process parameters such as fracturing scale, injection rate and sand-liquid ratio suitable for the target block were optimized. The idea and technology of multi-stage and multi-fracture support for complex fractures are put forward to optimize the proppant types of fractures at all levels in the fracture network. The flow rate - temperature - concentration coupled graph was established to form the whole process of slickwater continuous sand addition. The field application effect of this technology is obvious, and it has important guiding significance to improve the reconstruction effect of similar reservoirs..
