摘要
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.关键词
