摘要/Abstract

摘要： 为解决尼日尔Agadem复杂地貌沙漠油田因钻机搬迁及材料运输困难、地层复杂，导致钻井效率低，钻井成本高的问题，保障油田效益开发。基于复杂沙漠地貌及条带状油藏分布特点，提出了应用小规模"工厂化"（3~5口井）钻井工艺，通过地质工程经济一体化优化丛式井规模、井场位置、井口布置、井眼轨迹及井身结构设计，优化钻井液体系及重复利用，优化PDC+螺杆一趟钻及固井质量保障技术，钻机设备改造及优化平移工序，提高工厂化钻井效率及固井质量。实际应用表明，优化形成的小规模"工厂化"钻井模式及配套技术，可有效提高复杂断块沙漠油田钻井效率，大幅降低钻井成本。

Abstract: The Agadem Oilfield of Niger is located in the Sahara desert area, and the bad natural environment, and drilling rig moving and material transportation difficulties lead to low drilling efficiency and high daily operation cost drilling investment. Based on the analysis of the reservoir new well plan characteristics, we put forward the application of small-scale factory drilling to reduce the well site construction cost, improve the efficiency of the drilling rig moving, so as to improve drilling efficiency and material utilization, achieve the purpose of reducing drilling cost through rig moving process optimization, cluster well site location optimization, well slot and borehole trajectory optimization, casing program optimization, drilling fluid system optimization and reutilization, PDC + motor one trip drilling and cementing quality security technology research. Actual construction application proves that small-scale factory drilling and matching technology apply successfully in the field with remarkable effect.

Key words: desert oilfield, complex fault block, small-scale cluster wells, factory drilling, one trip drilling
