摘要

设计特点和使用水基解决方案的需求使得确保直井无故障钻井的任务变得非常简单。这项工作是跨学科方法分析井筒不稳定机制的一个例子。不稳定可以由复杂的原因引起,在这种情况下,标准的地质力学计算不足以解决问题。工程计算和实验室化学研究被整合到地质力学建模的过程中。在这三个领域提出的建议是相互依存、不可分割的。要取得良好的效果,必须同时遵守一套措施。该项目的关键任务是:确定钻井密度,起下钻条件,钻井液流变性参数,选择最佳抑制粘土膨胀的体系。

Interdisciplinary Approach for Wellbore Stability During Slimhole Drilling at Volga-Urals Basin Oilfield
The design features and the need to use a water-based solution make the task of ensuring trouble-free drilling of vertical wells non-trivial. This work is an example of an interdisciplinary approach to the analysis of the mechanisms of instability of the wellbore. Instability can be caused by a complex of reasons, in this case, standard geomechanical calculations are not enough to solve the problem. Engineering calculations and laboratory chemical studies are integrated into the process of geomechanical modeling. The recommendations developed in all three areas are interdependent and inseparable from each other. To achieve good results, it is necessary to comply with a set of measures at the same time. The key tasks of the project were: determination of drilling density, tripping the pipe conditions, parameters of the drilling fluid rheology, selection of a system for the best inhibition of clay swelling.
