1results about How to "Achieve reasonable control" patented technology

The application discloses a fracturing method for reducing the influence of fracturing on a fault, and comprises the following steps: according to the fault type, the fault extension, the distance between the fault and the fracturing section and the micro-fracture development degree, the maximum displacement and the maximum injection liquid volume of the first section fracturing construction are determined; supercritical carbon dioxide is used as a pre-fluid to perform the first section fracturing construction; according to the distance between the fault and the fracturing section, the microseismic event spatial distribution monitored in the first section fracturing construction and the micro-fracture development degree between the two fracturing sections and the fault, the minimum time interval of the adjacent construction section is determined; the micro-fracture development degree between the fracturing section and the fault is rechecked, the maximum displacement and the maximum injection liquid volume of the second section fracturing construction are determined; the second section fracturing construction is performed based on the minimum time interval; and the above steps are repeated until the fracturing construction of all sections is completed. The application can be directly applied to an oil and gas development site, greatly reduces the influence of fracturing on the fault, and achieves the purpose of safe fracturing.
