油基钻井液提切剂标准用基浆探讨

摘要：

为了满足高温深井、大斜度定向井、页岩长水平井等复杂井的钻探需求，提高油基钻井液的切力相当重要。目前提切剂产品标准制定不统一，均为各企业标准，且没有统一的基准物，无法对提切剂进行对比分析。收集了6种现场用提切剂，讨论了提切剂评价所需的基浆，为提切剂的检验统一标准基础，同时为提切剂标准的制定提供参考，有利于提切剂质量分析。

Abstract:

In order to meet the drilling needs of complex wells such as high-temperature deep wells, highly deviated directional wells, and shale long horizontal wells, it is important to improve the shear force of oil-based drilling fluids. At present, the product standards for rheology modifiers are not uniform, which are all enterprise standards without unified reference material. Based on the collected test data of 6 rheology modifiers and experimental data, the required base mud for the evaluation of rheology modifiers is discussed, providing a basis for the inspection of rheology modifiers and reference for the development of rheology modifier standards, which is beneficial for the quality analysis of rheology modifiers.
