油基钻井液提切剂标准用基浆探讨

Exploration of Standard Base Mud for Oil-based Drilling Fluid Rheology Modifier

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。

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.
