| 中文摘要:在地质勘探钻井中一般不需要进行井口压力控制。辽西金羊盆地“羊D1” 钻井采用地质勘探井的钻井工艺方法进行油气勘探，需要预备有井口压力控制措施。地质钻井设备和井控装置如何耦合是本文讨论的重点。以该井为例，介绍了用全液压岩心钻机全孔金刚石绳索取心钻进工艺施工油气勘探井的施工工艺。钻进中综合考虑了YDX-6型全液压岩心钻机平台的下方空间尺寸、井身结构设计以及本钻井的井口压力控制等要求，选择和设计了一套满足小口径取心钻探施工要求的井控装置。 |

| Abstract:Generally, it is unnecessary to control wellhead pressure in geological exploration drilling, while for Yang D 1 well in Jinlingsi Yangshan basin of west Liaoling, the oil and gas exploration was carried out with the drilling method of geological exploration wells, wellhead pressure control measures should be prepared, and the coupling of geological drilling equipment and well control device is the focus of this paper. Take this well as the example, the construction process of oil and gas exploration well with full hydraulic core drilling rig for full hole diamond core drilling is presented. The space dimension below YDX-6 full hydraulic core drilling machine platform, casing program design, wellhead pressure control and some other requirements were taken into account in drilling operation, a set of well control equipment is determined and designed, which can meet small-diameter core drilling construction. |
