摘要
井喷失控是石油及天然气开发中出现的重大恶性事故 ,它将严重危及人民的生命财产 ,污染良田 ,破坏生态环境 ,造成地下资源损失。文章利用空气中紊动射流理论 ,视失控井喷流为一束沉没自由紊动射流 ,分析喷流形状特征尺寸和速度场分布及参数的确定方法 ,为失控井喷着火井处理方案分析 ,处理设计及处理作业提供基础数据 ,达到快速清障、灭火、重建井口控制系统。
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.
