摘要
总结多年来水平井随钻地质导向钻井施工的实际经验,结合吐哈各油田不同的油藏特征,提出了吐哈油田水平井随钻地质导向的技术模式。主要内容包括:建立了"预测-验证-修正-寻找-确认-追踪"的"六步法"工作流程,提出了"标志层"的概念和确定原则,并初步筛选了各油田的"标志层",评价了目前常用随钻跟踪技术在吐哈油田不同油藏的适应性和组合应用方法,完善了以地质综合分析为基础、油藏和工程相结合的水平井地质导向技术。
This paper summarized the practical experiences on geological steering while drilling horizontal wells, and proposed the technique model for MWD geologic steering technique of horizontal well for Tuha Oilfield considering its special characteristics. It includes six-step-method prediction-validation- correction- searching- determination- track working flowing chart. The index-bed concept and determination principles were proposed. The initial index bed for each reservoir was identified. The applicability and combination of commonly used geological steering while drilling in Tuha Oilfield were evaluated. The geological steering while drilling technique was improved based on geological comprehensive analysis combined with reservoir and engineering.
