【摘要】：隨著社會的不斷發(fā)展,人們對能源的消耗逐年遞增,能源緊張問題一直困擾著現(xiàn)代社會。作為蘊藏豐富的資源,我國正積極開發(fā)頁巖氣能源。頁巖氣開發(fā)開采過程中通常需要使用油基泥漿,這將導致大量含油鉆屑的產(chǎn)生。含油鉆屑的處置不當可能對周邊環(huán)境造成嚴重的破壞,而我國頁巖氣開采主要集中在四川、重慶等人口密集地區(qū),如果不能合理的處理含油鉆屑,可能對周邊人群造成嚴重的危害。現(xiàn)有的含油鉆屑處理工藝存在著多種弊端,例如資源浪費、環(huán)境污染、處理周期長等。系統(tǒng)研究含油鉆屑新的處理工藝己成為當務(wù)之急。 論文將微波應(yīng)用于含油鉆屑的處理工藝中,以研究高效、節(jié)能、環(huán)保的鉆屑處理工藝為目標,對微波輻射中的鉆屑進行系統(tǒng)分析： (1)本文對微波熱脫附含油鉆屑工作機理進行研究,發(fā)現(xiàn)了含油鉆屑處理機理與常規(guī)干燥機理的差別。 (2)本文對影響含油鉆屑脫附效能的各項因素進行了系統(tǒng)研究。實驗結(jié)果表明：微波作用時間集中在反應(yīng)初期,盲目延長處理時間無益于高效處理；微波場強大小對鉆屑處理效率有較大影響；鉆屑處理量的適量增加可提高微波能量的利用率。 (3)針對各項因素實驗結(jié)果提出應(yīng)用優(yōu)化建議,并提出利用處理干化物控制鉆屑初始狀態(tài),綜合優(yōu)化鉆屑處理效果,并設(shè)計實驗驗證設(shè)想。 (4)通過對處理鉆屑的熱失重分析,檢驗微波熱脫附效果,證明該方法的可行性； (5)分別分析了熱脫附固、液產(chǎn)物成分,證明了鉆井液循環(huán)利用的設(shè)想,提出了固體廢渣的差異化處理要求； (6)論文以實驗結(jié)果為基礎(chǔ),以工業(yè)化應(yīng)用為目標,對含油鉆屑微波熱脫附處理實驗樣機進行了概念化設(shè)計,為進一步研究指明了方向。 通過對鉆屑素質(zhì)的調(diào)整和處理工藝的優(yōu)化,微波熱脫附含油鉆屑的處理效果大幅提高。實驗檢測表明,優(yōu)化后鉆屑含油率達到0.4364%,遠低于相關(guān)法規(guī)規(guī)定的1%含油率,甚至低于目前規(guī)定的最高標準0.5%。
[Abstract]:With the development of society, the consumption of energy is increasing year by year. As a rich resource, China is actively developing shale gas energy. Oil-based mud is usually used in shale gas production, which will lead to a large amount of oil-bearing drilling debris. Improper disposal of oil-bearing drilling debris may cause serious damage to the surrounding environment. However, shale gas production in China is mainly concentrated in densely populated areas such as Sichuan and Chongqing. If it is not reasonable to deal with oil-bearing drilling debris, May cause serious harm to the surrounding crowd. There are many disadvantages in the existing treatment process, such as waste of resources, environmental pollution, long treatment period and so on. It is urgent to study the new treatment technology of oil-bearing drilling chip systematically. In this paper, microwave is applied to the treatment process of oil-bearing drilling chip. Aiming at the research of high efficiency, energy saving and environmental protection, the drilling chip in microwave radiation is systematically analyzed. 1) in this paper, the working mechanism of microwave thermal desorption of oil-bearing cuttings is studied, and the difference between the treatment mechanism of oil-bearing cuttings and that of conventional drying is found. In this paper, the factors that affect the desorption efficiency of oil-bearing drilling cuttings are systematically studied. The experimental results show that the microwave action time is concentrated in the initial stage of the reaction, the blind prolongation of the treatment time is not beneficial to the efficient treatment, and the microwave field intensity has a great influence on the treatment efficiency of drilling chip. The utilization rate of microwave energy can be improved by increasing the amount of drilling chip. 3) according to the experimental results of various factors, the paper puts forward some suggestions for application optimization, and puts forward that the initial state of drilling chip is controlled by treating dry matter, synthetically optimizes the effect of drilling chip treatment, and designs experiments to verify the assumption. 4) the feasibility of this method is proved by the thermogravimetric analysis of the treatment of drill chips, and the effect of microwave thermal desorption is verified. (5) the thermal desorption solid and the composition of liquid product are analyzed respectively, the assumption of drilling fluid recycling is proved, and the requirement of differential treatment of solid waste residue is put forward. 6) based on the experimental results and the industrial application, the experimental prototype of microwave thermal desorption treatment of oil-bearing cuttings is conceptualized, which points out the direction of further research. By adjusting the quality of drilling chip and optimizing the treatment process, the treatment effect of microwave thermal desorption of oil-bearing cuttings is greatly improved. The experimental results show that the oil content of drilling cuttings after optimization is 0.4364, which is far lower than the oil content of 1% stipulated by relevant laws and regulations, and even lower than the highest standard of 0.5% stipulated at present.
