The Expansion Of Hydraulic Fracture Morphology Of Rocks And Formation Mechanism

To increase the production and injection of oil and gas wells, hydraulic fracturing is an effective method of oil and gas layer transformation. At present, Fracturing theory has a rapid development in our country. Fracturing technology has increasingly got everyone’s attention, and the fracturing technology need to develop and improve.The fracturing stress analysis and the calculation of the block were based on the ground in an oilfield. The corresponding summary analysis of crack propagation mechanism was made in the case of hydraulic rock fracturing. The morphology of the rock cracks and expansion was calculated.The main contents are:1)The research status at home and abroad study of hydraulic fracturing summary. For a certain oil field fracturing block calculation of ground stress experiment. Improve the application of in-situ stress in fracturing. 2) Summarizes the existing analysis of the fracturing operation curve interpretation. To deepen the understanding and try new explanation.3) Simulated fracture morphology by the software. Thereby have a qualitative understanding of fracturing expansion.4) The simulation of fracture morphology and crack propagation mechanism were analyzed and summarized.5) Summarizes the results of the above studies to form hydraulic fracturing in rock crevices and propagation mechanism, ultimately derived theoretical summary.
