| 中文摘要:哈深斜1井是胜利油田部署的一口重点风险预探井，该井为双靶点定向井，具有井斜角大、稳斜段长、水平位移大的特点。作为风险预探井，可借鉴的邻井实钻资料少，地层岩性、地层压力及层段变化不确定性因素相对较大，确定合理的井身结构、轨道类型、钻井液性能以及相关配套工艺措施是保证该井顺利施工的基础。在对有限的邻井资料进行详细分析的基础上，总结出本井钻井工程设计的技术难点，并有针对性的从井眼轨道设计、井身结构设计、钻具组合及钻井方式选择、钻井液设计和固井设计5个方面提出优化方案及技术措施，为胜利油田风险预探井的设计与施工提供了技术支持和理论依据。 |

| Abstract:Well Hasheng-X1 is an important risk wildcat in Shengli oilfield, which is a directional well with double targets with high deviation angle, long steady inclined section and large horizontal displacement. As a risk wildcat, there is less drilling data of adjacent wells and there are uncertain factors of formation lithology, formation pressure and layer section variety. It is an important basis to ensure smooth construction to determine reasonable casing program, optimized trajectory, good mud performance parameters and other relevant technical measures. Based on the detail analysis on the very few information, the optimized schemes and technical measures were proposed in well trajectory design, casing program design, bottom hole assembly & drilling method selection, drilling fluid design and cementing design; these above could be the technical support and theoretical basis to the design of the risk wildcat in Shengli oilfield. |
