The natural fracture and regional geostress determine the fracture propagation together, which makes it difficult for conventional methods to predict the fracture propagation direction in different positions. But the fourdimensional fracturing monitoring results are used to constrain ant body tracking technology, and then to predict the stress weak point, which can indicate the direction of fracturing grow. 172 stress weak points are identified via 51 layers, use the improved ant tracking method to match them by adjusting the parameters such as initial boundary, tracking deviation, illegal step length, legal step number and stop standard. The results are applied to verify the fracture zones of 5 newly monitored vertical wells and 2 horizontal wells, and the fracture trend is consistent with the prediction results, and the complexity of the predicted result has a good correlation with the productivity of the fractured wells. It shows that the fracture trend distribution predicted by this method is accurate, which provides reliable support for later complex fracture fracturing and well location deployment.
