摘要
PeriScope随钻测井具有独特的定向测量,对流体和地层边界非常敏感的特点,它能360°成像,显示最佳导向方位,由于探测深度大,并能提早发出警报,因而能及时对井下情况作出判断,制定相应的对策。现场应用6口井,油层钻遇率高达98.4%,开发效果显著,平均单井日产油25.4t,是设计产能的3.69倍。这项技术对于地质控制程度低、薄层、底水油藏具有广阔的应用前景。
PeriScope as a logging while drilling （LWD） tool is characterized by peculiar directional measurement, sensitivity to fluids and formation boundary, imaging in 360°, displaying optimal orientation and alarming ahead of time for in-time decision-making in deep investigation. Applied to six horizontal wells, it allowed the reservoir-encountered rates to reach up to 98.4%, with 25.4 t oil per day per well in average, being 3.69 times of design productivity. This technique is of wide applicable potentials for development of reservoirs with thin layer and bottom water.
