摘　　要：针对钻井液用润滑剂在实际应用中存在的问题,研制开发了固体润滑剂OCL-RH。该润滑剂是以石墨为主,辅以少量无毒矿物油及多种表面活性剂,经物理化学作用精制加工而成,为黑色固体粉末。经室内试验初步证明,固体润滑剂OCL-RH具有良好的润滑性、抗温性及一定的抑制性,与钻井液配伍性较好,对钻井液流变性无影响,并且具有一定的降滤失作用;可在淡水、海水和盐水钻井液中使用,最佳加量为1%,使用方便,维护处理简单;无毒、无污染,无荧光,不影响地质录井,有利于发现油气层。In order to solve problems of conventional lubricants for drilling fluid, a solid lubricant OCL-RH with black appearance was developed. OCL-RH is produced mainly from graphite, assisted with non-toxic-ity mineral oil and some surface active agents. Tests in lab illustrated that OCL-RH possesses good lubrication, thermal stability and some inhibition property. It not only provides some filtration control, but plays no role in drilling fluid rheological property development. In addition, it works well in clean water drilling fluid, seawater drilling fluid, salt-water drilling fluid, and the optimal addition is 1%. With no toxicity and no fluorescence, OCL-RH is an environmental friendly product.
