摘　　要：针对伊拉克Missan油田群包含大段泥岩、石膏层、硬石膏、盐层和塑性泥岩等复杂地层,使用了一种密度高达2.30g/cm3,且具有低活度、强抑制性,以及优良流变性能的HIBDRILL钻井液体系,该钻井液成功地解决了钻头泥包、高压盐水侵、软泥岩的蠕动和盐膏层的蠕变造成的缩径等复杂问题。In allusion to the complex formation in Missan Oilfields of Iraq that contained a large section of shale,anhydrite,salt-bed and plastic shale,a high density HIBDRILL drilling fluid system which had density of 2.30g/cm3,low activity,strong inhibition and excellent rheologic property was used in operation.It can be used for successfully resolving the problems such as the balling-up of drill bits,high pressure brine invasion and the undergauge caused by creeping of soft shale of gypsum beds.
