METHOD FOR CONTROLLING THE TRAJECTORY OF A HYDRAULIC FRACTURE IN STRATA-CONTAINING NATURAL FRACTURES

摘要

The method of controlling the parameters of a hydraulic fracture comprises creating a matrix of relationship between initial formation, injection and fracture parameters of and a predicted increment of a hydraulic fracture path. The matrix is used for retrieving and deriving the predicted increment of the fracture path, depending on the actual initial parameters of a fracture being created. The actual increment of the hydraulic fracture path is measured and compared with the predicted increment of the fracture path. In case of a discrepancy between the actual and predicted increments, the actual initial parameters of the fracture are changed.
