（一）“六五”期间，我们在研制成功S-S润滑剂、YZ-84润滑剂以及LPC抗钙添加剂的基础上，还成功地研制了S-S、YZ-84润滑剂与OP，平平加、吐温非离子表面活性剂，以及与LPC抗钙添加剂复配的复合型润滑剂12种，它们均能抗5000ppm左右浓度的Ca~(++)侵，其中与LPC抗钙添加剂复配的复合型润滑剂抗Ca~(++)能力达到10000ppm。我们研制的复合型润滑剂在本局261、264大队，以及江西省地矿局909大队受Ca~(++)强烈污染的地层总共试验了2857m进尺，取得了较好的经济效益：
(A) During the “Sixth Five-Year Plan”, based on the successful development of SS lubricants, YZ-84 lubricants and LPC anti-calcium additives, we successfully developed SS, YZ-84 lubricants and OP, Twelve kinds of complex lubricants combined with LPC anti-calcium additive were able to resist Ca ~ (++) invasion at a concentration of about 5000ppm. Among them, the complex with LPC anti-calcium additive Lubricant anti-Ca ~ (++) capacity of 10000ppm. We developed a comprehensive lubricant 261,264 brigade in this Council, and the Jiangxi Provincial Bureau of Geology and Mineral Resources 909 brines strongly contaminated by Ca ~ (++) a total of 2857m footage test footage, and achieved good economic benefits:
