两层合采井分层测压技术研究

Research of zonal pressure measuring technique in two-reservoir commingled producing well.

针对两层合采井无法进行分层压力测试这一问题 ,开展了两层合采井分层测压技术研究。结合两层合采井特殊的举升工艺 ,对井下仪器与井下工具进行了一体化设计 ,通过特殊的传压结构 ,井下仪器可以同时检测葡萄花层和扶余层的压力 ,通过电缆将整合调制后的数据传输至地面仪表中 ,地面仪表具有存储和直读两种工作方式。

We develop a zonal pressure measuring technique in two reservoir commingled producing well aiming to solve the problem that we could not measure that before,and integrally design downhole instruments and tools combining the specific lifting mandrel in two reservoir commingled producing well. The downhole instruments can simultaneously inspect the pressure of reservoir Putaohua and that of reservoir Fuyu by specific pressure conducting structure. The data after integrated modification are transferred to the surface equipment through a mono conductor cable, the surface equipment can work at two modes, memory and direct reading. On site testing results proves that the technique can meet the demands of zonal pressure measuring in two reservoir commingled producing well.
