| Abstract: | Blow out lost control is a serious accident for oil and gas development, which will harm people′s life and property, pollute agricultural fields, destroy ecological environment, and make underground resource losing. Using the jet theory of air turbulent motion, the article regards the lost control blowout flow as a free turbulent jet flow, analyzes the characteristics of jet flow shape, the distribution of its velocity field, and the parameters identifying method. This method provides the basic data for the handling program, design and job of the blowout firing well, so as to clear away obstacles, distinct fire, rebuild well head system, and control the jet flow rapidly. |
