钻探中为防止钻具粘附卡钻，降低井内的提升和旋转阻力，常常要用到大量的润滑剂。文中分析了６种不同类型的植物油下脚料的基本性质：酸价、色值、密度、含皂量、皂化价、磷脂量、挥发分等，并在一定条件下，通过化学反应将其改性后制成了润滑剂。测定了润滑剂在不同的钻井液体系中的基本性能，得到润滑性能与油品的酸价成正比，与磷脂含量成反比的特性。通过现场试验证明了此种润滑剂产品具有良好的降摩阻、配伍性和使用中不易发泡等特性。
Drilling to prevent sticking drill pipe stuck, reducing the shaft lift and rotation resistance, often to use a lot of lubricant. In this paper, the basic properties of six different types of vegetable oil scraps are analyzed: acid value, color value, density, soap content, saponification value, phospholipid content, volatiles and so on, and under certain conditions, it is modified by chemical reaction After made of lubricant. The basic properties of lubricants in different drilling fluid systems were determined, and the lubricating properties were directly proportional to the acid value of the oil and inversely proportional to the phospholipid content. The field test proves that this kind of lubricant has a good friction reduction, compatibility and easy to use in the foam characteristics.
