In order to clear up the mechanism of water control and shutoff by continuous packer filling and the main controlling factors of filling, a mathematical model of fracture filling was established to simulate the changes in natural fracture opening, conductivity, filling degree, and filling volume with pressure in the filling process, the main factors affecting the filling process were analyzed, and the effectiveness characteristics and reasons were summarized in conjunction with the actual oilfield conditions. Research shows that the initial fracture opening and fracture direction are the main geological factors that affect the water control construction process; whether the pumping pressure in the filling process, especially in the initial stage, reach the threshold of effective filling pressure has a significant impact on the fracture plugging effect. This study provides a reference for the optimization and effect evaluation of measure wells, and lays a foundation for the quantitative study of water control by supersaturated fracture filling.
