无论是国际还是国内,石油天然气井喷事故屡见不鲜。我国石油天然气井控应急救援技术发展历程和建设现状如何?发展方向是什么?井控,就是采用一定的方法,平衡地层孔隙压力,保证作业施工的顺利进行。根据所采取的控制方法不同,可以把井控作业分为一次井控、二次井控和三次井控。一次井控是指依靠适当的钻井液密度,来控制住地层孔隙压力,使地层流体不能侵入井内,井涌量
Whether it is international or domestic, oil and gas blowout accidents are common. What is the development direction and the status quo of the construction of the well control emergency rescue technology for oil and natural gas in China? Well control is to use certain methods to balance the formation pore pressure and ensure the smooth operation of the construction. According to the different control methods taken, well control operations can be divided into primary well control, secondary well control and three well control. A well control refers to relying on the appropriate drilling fluid density, to control the formation pore pressure, so that fluid can not intrude into the well, the well volume
