摘要
Abstract
Under the control of the formation stress, the two-wing hydraulic fracture geometry has a limited controlling drainage area. Oil & gas well with this type fracture generally have a high initial production rate, but it declines rapidly. The multiple fracturing is a novel stimulation technique that not only increase in the number of the main fractures but also can rigorously control the fracture geometry. The number of directions of the main fractures can be controlled by the appropriate treatment parameters and technologies. In this way, these fractures can reach multiple the hydrocarbon reservoir areas simultaneously, which will increase the drainage area dramatically and keep the production rate in a higher level for a longer time. Based on the creating mechanism of multiple fractures, the feature of the minifrac and the G-function in multiple fracturing are induced. The field application indicates that multiple fracturing technique can greatly enhance the productivity of the well.关键词
