【摘要】：油基钻井液应用中产生的废弃物的高效处理难度大是制约其广泛应用的重要原因和难点之一,针对油基钻井液技术难点,研发了高效的岩屑除油剂(CYJ-1)及针对废弃油基钻井液的破乳剂配方。研发的除油剂为一种润湿剂,通过改变岩屑表面润湿性实现除油。实验结果表明,其除油率高达98.27%,除油效果良好。通过破乳实验确定了破乳剂单剂种类及复配比例,并确定了破乳剂配方的最佳反应温度、反应时间、离心速度、离心时间等条件。将研究成果在现场云页平1井进行了初步试验。现场试验表明,CYJ-1及废弃油收油剂配方效果良好,处理效率高,实现了基油的回收利用,固相排放达到要求,有效降低了钻井液成本,减少了环境污染。
[Abstract]:The difficulty of high efficient treatment of waste produced in the application of oil-based drilling fluid is one of the important reasons and difficulties that restrict its wide application, aiming at the technical difficulties of oil-based drilling fluid. A highly effective cuttings oil remover (CYJ-1) and a demulsifier formulation for waste oil-based drilling fluid were developed. The deoiling agent is a wetting agent, which can remove oil by changing the wettability of the cuttings surface. The oil removal rate of the demulsifier is up to 98.27, and the oil removal effect is good. Through the demulsification experiment, the types of the single demulsifier and the proportion of the demulsifier are determined, and the optimum reaction temperature, reaction time and centrifugal speed of the demulsifier formula are determined. Centrifugal time and other conditions. The preliminary test was carried out in well Yunye Ping 1. The field test shows that the formulation of CYJ-1 and waste oil recovery agent is good, the treatment efficiency is high, the recovery and utilization of base oil are realized, and the solid phase discharge meets the requirements. The drilling fluid cost is reduced effectively and the environmental pollution is reduced.
