随钻测压工具Geo-Tap在渤中25-1油田E3S井的应用

Application of Geo-Tap in Well E3S of Bozhong25-1 Oilfield

为了获得渤中25-1油田目前的地层压力数据,验证该油田储层的压力衰竭情况,在E3井侧钻过程中使用哈利伯顿随钻测压工具Geo-Tap在打开油藏的同时测量了地层压力。为获得真实的压力数据,在钻井液等外来液体尚未渗入地层的情况下,吸取地层原始液体进行测量。根据测量所获得的数据,可确定地层压力及其地层相关物性参数,这些数据对后续的采油作业具有指导作用。简要介绍了随钻测压工具Geo-Tap的工作原理、测试流程及在E3S井中的测试过程。

In order to obtain current formation pressure to verify reservoir pressure declining, formation pressure while drilling （FPWD）, Geo-Tap was used to evaluate formation pressure while drilling through pay zones in Well E3. Before drilling fluid infiltrate into formation, the original formation fluid was retrieved. Using the measured data, the initial formation pressure and formation-related parameters are determined. These data are important for the following oil production. This paper introduces the working principle of Geo-Tap and field applications on Well E3S.
