排612—平279井位于新疆准噶尔盆地车排子地区的一口三开水平井,其钻探目的是为了开采排612区块白垩系超稠油油藏。该井目的层油藏埋深较浅(垂深仅300 m左右),造斜率高,施工速度快,地层非均质性严重,增加了井眼轨迹控制的难度。通过分析排612-平279井可能出现的施工难点、优化剖面设计、优选动力钻具、钻具组合以及仪器,成功的完成了该井的钻探要求,对该区块后续水平井的施工具有一定的指导意义。 Block 612 - Ping 279 Wells are located in a tri-level horizontal well in the Chepaizi area of ​​the Junggar Basin in Xinjiang. The purpose of drilling is to extract the Cretaceous super-heavy oil reservoirs in Block 612. The reservoir in the target reservoir is shallow (only about 300 m deep) with high slope-making rate, high construction speed and serious formation heterogeneity, which makes it more difficult to control well trajectory. By analyzing the possible construction difficulties in 612-Ping-279 well, optimizing the profile design, preferably the power drill, the drilling assembly and the instrument, the drilling requirements of the well were successfully completed, and the construction of the subsequent horizontal well in the block was certain The guiding significance.
