在油气田的开发过程中,试气是井下作业中从钻井到气田开发之间非常重要的一道工序,是指利用一套专用的设备及一定的技术措施,来降低井内液柱的压力,使产层内的流体流入井内并在诱导作用下进入地面,然后对井下的气层进行直接测试,从而取得有关地层内的油、气、水层的产能、压力、温度和油、气、水的物理性质等资料的一种工艺过程。 In the process of oil and gas field development, test gas is a very important process from drilling to gas field development in downhole operations. It refers to using a special set of equipment and certain technical measures to reduce the pressure of the liquid column in the well, The fluid in the layer flows into the well and enters the ground under the inductive effect, and then the downhole gas layer is directly tested to obtain the physical, physical, mechanical, structural, energy, temperature, and oil, gas, Nature and other information of a process.
