摘　　要：石南31井区清水河组砂砾岩油藏有效厚度小,平面非均质性严重,经4年开采,目前存在水平井水淹水窜严重、含水上升速度较大、产量递减加快的问题。同时由于测试工艺技术的受限,水平井的压力及温度监测资料缺乏,为分析油井泄油半径、井壁完善程度、控制面积及产出情况带来困难,影响油井动态分析与措施调控。对水平井压力监测的几种技术及应用情况进行了介绍,用现场测试实例证明了其可靠性和成熟性,为分析油藏目前地层压力状况及生产动态提供了可靠的资料和依据。Effective thickness of glutenite reservoir in the Qingshuihe group is small and whose areal heterogeneity is serious. After nearly four years of produced. now,the reservoir has series of problems at present,such as: horizontal well water flooding channeling serious,water cut raise speed and production decline accelerating. Meanwhile as testing technology limited,the lack of pressure and temperature monitoring data of horizontal wells,brings the difficulty for analysis of oil drainage radius,well-bore maturity,area of influence and the output and influences the well performance analysis and control measure. By introduction of several technologies of pressure monitoring and the application situation to the horizontal well,the reliability and maturation of this technical have been proved by field experiment,which provides a liable data and reference for the present formation pressure status and production dynamic. This technical for analysis of formation pressure and production performance provides a reliable data and the theoretical foundation.
