摘　　要：钻井过程中产生的钻屑、废液等废弃物含有多种有害成分,国内外处理钻井废弃物的技术多达十几种,不同处理技术的适用范围、处理效果及处理成本存在较大差异。针对正在推广应用的板框压滤、萃取、高温氧化、高温热解、高效物理分离等钻井废弃物不落地处理技术,研究了随钻处理和集中处理的费用构成及成本差异。通过分析影响钻井环保处理成本的主要因素和单一定价法的3种局限性,考虑钻井周期与处理量提出了采用二部定价法确定钻井废弃物随钻处理价格的思路,并进一步分析了二部定价法的3个优点和实用性。在此基础上,分别规范了随钻处理、集中处理的费用构成和计算方法。Several hazardous substances can be easily found among drilling waste of drilling cuttings and waste water. There are more than ten methods used for waste treatment. However, different methods have their own application extent, and treatment effect and cost. Aiming at five approaches of drilling waste zero discharge,such as plate-frame pressure filtration, extraction, high-temperature oxidation, high-temperature pyrolysis, and efficiently physical separation, the expense structure and cost difference of both treatment while drilling and centralized treatment are analyzed. Furthermore, the main factors affecting treatment cost and three limitations from single pricing method are also presented. And another twopart pricing method is suggested to determine the price in treatment while drilling. This two-part pricing method has three advantages and its application scope. Finally, for treatment while drilling and centralized treatment, the expense structure and its calculation ways are also regulated.
