摘要：Oil-based drilling fluids are widely used in oil and gas exploration operations where the drilling process is complex, but there are also a lot of oily drill cuttings that are harmful to the environment. At present, many oily drill cuttings treatment technologies have emerged on the international market, mainly including thermal desorption, solvent extraction, cuttings dryer, incineration, bioremediation and solidification/stabilization, et al. However, there is not yet a technology that can be applied to all treatment conditions. So, an evaluation system is urgently needed to selectively screen treatment technologies according to operating conditions. Therefore, this paper introduces the fuzzy evaluation method, through the comprehensive comparative analysis of main treatment technologies, to determine the evaluation index of the oily drill cuttings treatment. Based on this, a fuzzy evaluation index system is established, and the evaluation process of fuzzy evaluation is expounded. The research results provide a theoretical guidance for choosing the right oily drill cuttings treatment technology for drilling operations.
