摘　　要：地层压力测试在油藏开发设计中至关重要,为研究地层压力剖面,估算地层渗透率,确定流体界面,防止井漏、井喷等井下事故的发生提供可靠的数据。随钻地层压力测试可高效获取高精度地层压力值,确保井下安全。介绍了中海油服自行研制的随钻实时地层压力测试器(IFPT)的工作原理、测试流程以及在渤海X油田的应用效果。现场应用表明,IFPT测压技术验证了储层压力的变化情况,为后期调整开发注采计划提供了重要的参考。Formation pressure test is important in reservoir development design.It provides reliable data for studying formation pressure profile,estimating formation permeability,determining fluid interface and preventing downhole accidents such as lost circulation and blowout.Formation pressure test while drilling can obtain high-precision formation pressure value efficiently and ensure downhole safety.The working principle and testing process of the real-time formation pressure tester(IFPT)developed by COSL and its application in X oilfield in Bohai are introduced.Field application shows that IFPT pressure measurement technology verifies the change of reservoir pressure and provides an important basis for adjusting the injection and production plan of development in the later stage.
