镇泾油田HH37P1水平井钻完井技术

Drilling and Completion Technology Used in Horizontal Well of Zhenjing Oilfield

摘要:

为评价水平井开发镇泾油田长8油藏的经济技术可行性，部署了HH37P1水平井。分析了该井的施工难点，提出了相应的技术对策。现场施工中通过优化钻具组合、控制井眼轨迹、调节钻井液性能及配合相应的工程工艺技术，使HH37P1水平井顺利完钻。通过测井资料结合录井显示，采用预置管柱完井方式配合后期压裂改造，初见成效。HH37P1井的成功实施为有效开发镇泾油田提供了新的途径。

Abstract:

To evaluate economic and technical feasibilities of Chang 8 reservoir in Zhengjing oil field developed by horizontal well, HH37P1 well was arranged. The construction difficulties were analyzed with corresponding technical measures. By optimizing bottom hole assembly, controlling well trajectory, regulating drilling fluid properties and combining corresponding engineering technology, HH37P1 horizontal well was successfully drilled. The combination of logging data and logging showed the initial success by using presetting pipe string completion and following fracturing reformation. The successful implementation of HH37P1 horizontal well provides a new approach to effective development of Zhenjing oilfield.
