【摘要】：油基钻屑含有大量的矿物油、乳化剂等化学药剂,成分复杂、处理困难,是页岩气等非常规油气开发的环保难题。为此,设计了一套油基钻屑电磁加热脱附处理设备,并进行了现场小试试验。通过检测电磁加热设备热脱附处理后的钻屑残渣含油率,分析试验过程中的温度变化规律,对设备处理油基钻屑的可行性进行了初步验证,并在此基础上优化了设备的主要运行参数:温度、负荷、时间。结果表明:1该电磁加热脱附处理设备对于油基钻屑具有良好的处理效果,处理后残渣含油率低于1%;2该设备适用范围广,可同时处理钻井过程中产生的编织袋、防渗塑料布等其他含油废物;3处理固控系统振动筛出渣(物料A)的最佳条件为温度375℃、进料负荷15 L/h、时间45 min;4处理固控系统离心机出渣(物料B)的最佳条件为温度350℃、进料负荷20 L/h、时间50 min;5电磁加热脱附炉内部温度的波动不受设定温度的影响,对不同负荷的物料也均能保证内部温度的稳定,具有稳定的控制温度能力和良好的保温效果。
[Abstract]:Oil based drilling debris contains a large number of mineral oil, emulsifiers and other chemical agents, the composition of complex, difficult to deal with, such as shale gas unconventional oil and gas exploitation of environmental problems.For this reason, a set of oil-based drilling chip electromagnetic heating desorption treatment equipment was designed, and the field test was carried out.By detecting the oil content of drilling chip residue after thermal desorption treatment of electromagnetic heating equipment and analyzing the rule of temperature change during the test, the feasibility of treating oil based drilling chip by the equipment is preliminarily verified.On this basis, the main operating parameters of the equipment are optimized: temperature, load, time.The results show that the electromagnetic heating desorption treatment equipment has a good treatment effect on oil based drilling chips, and the oil content of the residue after treatment is less than 1 / 2. The equipment can be used in a wide range of applications, and it can simultaneously handle woven bags produced during drilling.The optimum conditions for treating solid control system solid control system solid control system such as impermeable plastic sheet and other oily waste such as plastic sheet are as follows: temperature 375 鈩，
