摘要

摘要: 综述了国内外微锰加重钻井液的研究进展，分析了高密度钻井液用加重剂的优点及存在的问题，阐述了微锰加重材料的化学组分、理化性能、微观形状及粒度分布、Zeta电性、沉降动力稳定性、密度、酸溶性和莫氏硬度。与传统高密度钻井液用加重材料（重晶石和铁矿粉）相比，微锰具有颗粒小、呈球形、比表面积较高等特点，微锰加重钻井液表现出良好的流变性、沉降稳定性和润滑性，较好地解决了高密度钻井液的流变性与沉降性之间的矛盾。介绍了微锰对钻井液性能及储层保护的影响，给出了其在科威特北部深井、壳牌Cormorant North油田的过油管旋转钻井（TTRD）的现场应用结果。

Abstract: This paper summarizes the progresses made abroad in micro manganese weighted drill-in fluids, analyzes the advantages and disadvantages of weighting materials used in high density drilling fluids, and describes the properties of micro manganese powder weighting agent, such as its chemical composition, physic-chemical property, microscopic shape, particle size distribution, Zeta potential, dynamic stability, density, acid solubility and Mohs' scale of hardness. Compared with traditional weighting materials (barite and hematite etc.) used in high density drilling fluids, micro manganese powder has these properties such as smaller particle sizes, better sphericity and higher specific surface area. Drilling fluids weighted with micro manganese powder show good rheology, antisettling property and lubricity, satisfactorily resolving the contradiction between the rheology and anti-settling property of a high density drilling fluid. The authors have paid much attention in introducing the effects of micro manganese powder on the properties of drill-in fluids and reservoir protection, and presented the application results of the micro manganese powder weighted drilling fluids in north Kuwait and Cormorant North oilfields.
