摘要

钻井液中发现的固体，特别是加重材料，会堵塞地层孔隙，对地层造成严重损害。本研究调查了使用由微粉化钛铁矿或微粉化重晶石加重的油基钻井液系统引起的地层损害。测定了油基泥浆体系的流变性能。进行了高压/高温（HP/HT）静态过滤实验。岩心驱替系统用于模拟动态条件，允许钻井液在岩心表面循环，并测量渗透率损伤。计算机断层扫描（CT）扫描分析显示地层损伤和固体侵入深度。介绍了无损伤微细钛铁矿基OBM的现场应用，说明了其优点。

Evaluation of Formation Damage of Oil-Based Drilling Fluids Weighted with Micronized Ilmenite or Micronized Barite

Solids found in drilling fluids, particularly weighting materials, can cause significant formation damage by plugging of formation pores. This study investigates formation damage caused by using oil-based drilling fluid systems weighted by micronized ilmenite or micronized barite. Rheological properties of the oil-based-mud (OBM) systems were measured. High-pressure/high-temperature (HP/HT) static filtration experiments were conducted. A coreflood system was used to simulate dynamic conditions, allowing for drilling fluid circulation at the face of the core and measuring permeability damage. Computed-tomography (CT) scan analysis revealed formation damage and depth of solid invasion. The paper presents field applications of nondamaging micronized-ilmenite-based OBM, illustrating its advantages.
