摘要
为避免或减小水基钻井废物对环境造成的影响,苏里格气田本着“建一个气田,留一片绿色”的理念,对液相循环利用,固相外委处置,同时进一步探索钻井岩屑减量和资源化利用途径。文章通过对钻井岩屑成分分析,对泥浆池土壤和植被进行环境调研,进一步探讨钻井废物在苏里格气田的处置及资源化利用,介绍了2015年之前固化法的应用情况,2015年之后实施钻井液不落地技术的应用情况。提出优化钻井液体系,强化现场处置及监管力度,进一步实现源头控制及循环利用。同时,结合国内外钻井废物处置、再利用现状,积极探索钻井固废铺垫井场、铺垫油区道路等资源化利用方式。
To prevent or reduce the impact of water-based drilling waste on environment,Sulige Gas Field has been committed to the reuse of fluid,the reduction and resource utilization of drilling cuttings.Meanwhile,Sulige gas field put forward a concept that“building a gas field,leaving a piece of green”.In this study,we demonstrated a discussion on the disposal and resource utilization of drilling waste in Sulige gas field based on the content analysis of drilling cuttings and the investigation on soil and vegetation in the mud pool.The application of the solidification method before 2015 and the application of the drilling fluid non-landing technology after 2015 were also introduced.The implementation of the drilling fluid non-landing technology was analyzed from three stages:test,application,and promotion.Moreover,we pointed out three most serious issues of drilling fluid non-landing technology:no standards for drilling waste disposal and resource utilization,only a small part can be used for experimental brick making,lack of large-scale resource utilization test.
