【摘要】：油基钻井液因具有抑制性强、润滑性好、抗高温、抗污染、安全和钻速快等优点而被广泛应用在对非常规油气资源的勘探开发工作中,而其钻屑矿物油含量高、乳化严重、不易回收等缺点也成为环保治理的难点。为此,针对不同类型油基钻屑的物性特点,将高效清洗剂破乳清洗处理、油—水—固三相分离和石油微生物消除等3种工艺有机集成,试制出一套油基钻屑现场处理装置,形成了油基钻屑常温清洗—微生物联合处理技术。经过对4口井的油基钻屑进行放大试验,结果表明:油相回收率超过85%,清洗后废渣总石油烃含量小于2%,再经生物深度处理30天后,废渣中总石油烃含量降至0.3%以下,均达到相关标准的要求。结论认为:该联合处理技术实现了油相的回收再利用以及废渣的无害化处理,不仅有效解决了油基钻屑环保治理难题,而且还节约了钻井工程综合成本,具有良好的推广应用前景。
[Abstract]:Oil based drilling fluid has strong inhibition, good lubrication, high temperature resistance, anti pollution, safe and fast drilling advantages and is widely used in the exploration and development of unconventional oil and gas resources in the work, and the cuttings of mineral oil content is high, severe emulsification, difficult recovery disadvantages become difficulty environmental governance. Therefore, based on the characteristics of different types of oil-based drill cuttings, the efficient cleaning agent cleaning emulsion, oil water solid separation and oil and other 3 kinds of microbial elimination process of organic integration, developed a set of oil based drilling site processing device, forming a chip cleaning microbe combined at room temperature processing technology of oil based drilling. After the 4 wells oil based drill cuttings enlargement experiment results showed that the oil recovery rate of more than 85% of the total petroleum hydrocarbon content, residue after cleaning is less than 2%, the depth of biological treatment after 30 days, the content of total petroleum hydrocarbons from below 0.3%, Can reach the relevant standard requirements. Conclusion: the combined processing technology to achieve the reuse of waste recycling and harmless treatment of the oil phase, not only effectively solve the oil base drilling environmental governance problem, but also saves the comprehensive cost of drilling engineering, and has good application prospects.
