Description

油基泥浆岩屑旋流自转脱油方法和装置 技术领域
本公开属于页岩气钻井中含油固体废弃物环保处理领域，尤其涉及一种油基泥浆岩屑旋流自转深度脱油方法和装置，以实现页岩气开发过程中产生的废弃油基泥浆岩屑的无害化处理。具体地说，本公开提供了一种油基泥浆岩屑旋流自转深度脱油方法和装置。
背景技术
油基泥浆因有利于保护页岩气层、提高钻井速度、有效防止井壁坍塌等多种优势，在页岩气钻井中被广泛应用。页岩气井三开及水平段通常长达1500m以上，产生大量含油岩屑(单井产生量约250～500m 3)。油基泥浆岩屑含油率约10％～30％，己被列入《国家危险废物目录》(2016)，属于原油和天然气开采“废弃泥浆处理产生的污泥”，废物类别为HW08废矿物油，废物代码为071-001-08，若不加以无害化处理，对环境土壤、水体、空气都将造成污染。
油基泥浆岩屑处理的主要目标是实现废弃物无害化处理，最重要的技术指标是处理后废弃物中油的含量，其实质是油的脱除。目前主要采用的处理废弃油基泥浆岩屑技术有：高温焚烧法、化学萃取技术、热解析技术(热相分离)。
高温焚烧法对废弃油基泥浆资源化利用程度不高，且运输费用及风险较高。中国专利申请CN 201610863875.3公开了一种废弃油基泥浆固态残渣的处理方法，该工艺采用振动筛分-干燥-流化床焚烧-除尘-SCR(选择性催化还原)脱硝-双碱脱硫的工艺，实现了废弃油基泥浆固态残渣的彻底无害化。但整套工艺设备复杂、占地大、运行成本高、油回收率低，且工艺过程产生的气体容易产生二次污染。
中国发明专利ZL 201310645168.3、ZL 201410033209.8、ZL 201410033980.5、ZL 201410033210.0涉及利用LRET(废弃油基泥浆岩屑资源回收技术)技术处理废弃油基泥浆或钻屑并回收其中油基和废弃油基泥浆的工艺及装置，LRET技术采用常温深度脱附回收工艺，包括离心过滤、离心沉降、药剂常温深度脱附、蒸馏冷凝过程，以及回收循环药剂的过程，该技术可在常温常压下实现泥浆、泥浆添加剂、加重剂及药剂(99％)的连续回收，但其处理效率受废弃油基泥浆成分 影响较大，且偏高的药剂价格导致运行成本较高。美国专利US 8758629涉及一种类似的化学萃取方法，用一种环保萃取剂萃取钻屑包含的油分，继而用一种估计吸附剂吸附溶有油分的萃取剂，后加入一定量的氯化钾水溶液分离钻屑与吸附剂，达成了钻屑除油的目标，该方法的优点在于采用的萃取剂对环境友好无害，使用后的吸附剂经过再生，可重复使用，但处理周期长限制了处理量，振荡萃取7.5分钟，静置96小时后，钻屑内总石油烃含量仅能降至0.6％，未到达处理标准。
热解析技术因无需添加处理剂、除油较彻底等优点成为近几年国内外尝试较多的废弃油基泥浆岩屑处理手段。中国发明专利ZL 201410397190.5涉及一种主要利用摩擦生热方式对油基钻屑进行直接加热脱油的热解析处理方法，同时在SPE-188222-MS(Processing and Recycling Drill Cuttings at Source-Technology and Services Adhering to Zero Discharge Legislation(基于零排放标准的钻井岩屑过程与循环资源化技术和服务))、SPE-183600-MS(Solutions for Management of Oil on Drilled Cuttings in the New Deepwater Oil Province of Ghana(针对加纳新开发深水油区的钻井岩屑的治理方案))等文献中也有利用该技术处理废弃油基泥浆岩屑的报导，并且国际知名石油服务公司Halliburton和Schlumberger旗下M-I Swaco均有该技术的开发应用。Halliburton的美国专利US 9725973和US 9677354涉及一种回收废弃泥浆中的基础油的方法和装置，该方法用摩擦的方法加热钻屑，从而使钻屑中的油分、水分气化，再冷凝回收，该方法的优势在于用低于大气压下油分沸点的温度下使其气化，从而达到了降低能耗的目的，而缺点在于，该方法只能处理低含固率的处理对象，高含固率的泥浆容易对设备产生严重的磨损。中国发明专利申请CN 201610547026.7、CN 201710056325.5公开了通过高温烟气间接加热的热解析处理方法，同时杰瑞环保科技有限公司在SPE-184399-PA(Odor-Treatment Technology for Recovered Hydrocarbons From Oily Waste in a Thermal-Desorption Unit(热解析装置回收油类污染物中石油烃过程中臭气处理技术))报导其利用类似技术在现场应用的情况，且从2014年至今，中石化四川涪陵页岩气田尝试采用美国NOV公司开发的导热油间接加热的热解析处理装置对现场产生的废弃油基泥浆岩屑进行无害化处理。但无论是直接加热还是间接加热的热解析技术，在工程应用中一直存在能耗高、废气污染严重、泥浆体系被高温破坏、只能回收部分基油等问题。
中国发明专利申请CN 201210147625.1涉及一种沸腾床渣油加氢外排催化剂 的处理方法和装置，基于水热旋流脱附技术，通过(1)调控减粘、(2)旋流脱附分离、(3)油-水-催化剂三相分离及资源化利用三个过程，利用旋转流场的流动剪切力，使吸附油从固体颗粒表面和内部孔洞中脱附分离出来。水热旋流脱附技术用于外排催化剂除油同样在Jian-Ping Li(The enhancement on the waste management of spent hydrotreating catalysts for residue oil by a hydrothermal-hydrocyclone process(水热旋流工艺提高渣油加氢废催化剂无害化处理效果的研究)，Catalysis Today(今日催化)，271(2016)，163-171)的文献中进行了报导。中国专利申请CN201710821746.2公开了一种含油外排催化剂处理及分选回用方法和装置，通过(A)外排催化剂旋流洗涤与在线活化、(B)催化剂溶剂旋流自转气提、(C)高活性催化剂气流加速度分选、(D)高活性催化剂旋流再气提与颗粒捕集、以及(E)气体冷却与溶剂冷凝脱除等过程，对催化剂进行油相脱附和分选。上述技术均利用旋流器内的高流动剪切力和催化剂颗粒的高速自转，强化了催化剂颗粒孔隙中油的脱附过程，但上述方法和装置仅针对外排催化剂的除油处理和回用，虽然满足催化剂的处理要求，减少了石油类污染物对环境的污染并回收了部分油相和催化剂，但处理后固相含油率依然大于1％，水热旋流脱附技术处理后的固相含油率甚至高于5％，无法满足废弃油基泥浆无害化处理对固相中矿物油小于0.3％的要求。
由于现有废弃油基泥浆处理技术普遍存在能耗高、二次污染严重、处理成本高等问题，而已有的旋流除油技术又不能满足废弃油基泥浆无害化处理要求，因此，本领域迫切需要开发出一种高效、环保、节能、工艺流程简单的废弃油基泥浆岩屑处理方法和装置，以实现废弃油基泥浆及岩屑无害化处理的目标。
发明内容
本公开提供了一种新颖的油基泥浆岩屑旋流自转深度脱油方法和装置，从而解决了现有技术中存在的问题。
本公开所要解决的技术问题是：现有废弃油基泥浆岩屑处理技术难以对岩屑颗粒孔隙中携带的油进行高效分离，成本高、工艺复杂、容易形成二次污染。本发明利用三维旋转湍流场中岩屑颗粒的自转与公转耦合运动，强化固相表面油、毛细油和孔隙油的离心脱附，完成油气、固相的分离和富集，实现废弃油基泥浆岩屑中有机物的深度脱除。
一方面，本公开提供了一种油基泥浆岩屑旋流自转脱油方法，该方法包括以下步骤：
(1)体系粘度调控：通过气体介质与岩屑换热，降低油基泥浆岩屑的粘度以减小油、水与固体颗粒表面及孔道的相互作用力，从而便于在旋流场中分离；
(2)旋流自转脱油：油基泥浆岩屑颗粒在旋流场中存在自转与公转耦合运动，利用岩屑颗粒的自转强化固相表面油、毛细油和孔隙油的离心脱附，利用其公转产生的周期振荡的离心力完成油气、固相的分离和富集，从而实现岩屑孔道中油相的脱除；以及
(3)气液分离与回用：将步骤(2)中产生的含油混合物进行气液分离，实现基础油回用、气体介质循环以及岩屑无害化处理。
在一个优选的实施方式中，在步骤(1)中，体系粘度调控过程在旋流场中进行，通过旋流场中的湍流流场强化气体介质与废弃油基泥浆岩屑间的换热效率，从而将液体升温以实现降低其粘度的目的。
在另一个优选的实施方式中，在步骤(1)中，粘度调控的操作温度范围为70～200℃，根据不同废弃油基泥浆配方确定，低于废弃油基泥浆的额定使用温度。
在另一个优选的实施方式中，在步骤(1)中，气体介质包括空气、氮气、超临界二氧化碳气体、氢气、干气、低分气和天然气燃烧尾气。
在另一个优选的实施方式中，在步骤(2)中，油基泥浆岩屑颗粒在旋流场中为旋流公转与颗粒自转耦合运动，自转转速最高至5000转/秒，停留时间2～10秒。
另一方面，本公开提供了一种油基泥浆岩屑旋流自转脱油装置，该装置包括：
进气系统和与其连接的气体加热系统，以用于对气体介质进行加热；
与气体加热系统连接的旋流器组，以用于对废弃油基泥浆岩屑进行旋流自转脱油；以及

在一个优选的实施方式中，该装置还包括：与气体加热系统连接的输料系统，以用于运输处理前的废弃油基泥浆岩屑；与旋流器组连接的输料系统，以用于运输处理后的废弃油基泥浆岩屑；以及与输料系统连接的岩屑罐，以用于存储处理后的废弃油基泥浆岩屑。
在另一个优选的实施方式中，所述旋流器组为1～10级旋流器串联组合，并可 根据不同处理量需求进行多级并联。
在另一个优选的实施方式中，所述旋流器组的安装组合方式包括旋流器正装、旋流器倒装和旋流器正装与倒装组合。
有益效果：
本发明的方法和装置的主要优点在于：

具体实施方式
本申请的发明人经过广泛而深入的研究后发现，由于页岩非常致密、孔隙率极低、渗透性极差，孔隙率为2％～4％、渗透率为0.0001mD～0.1mD，废弃油基泥浆岩屑颗粒中的孔隙油难以从纳微孔道中脱离；而废弃油基泥浆岩屑颗粒在旋流场中，拥有最高至5000转/秒的自转速度，可提供大于粘滞阻力的离心力，从而强化孔隙油的脱除；旋流自转过程时间短，且加热降粘所需温度也低于传统工艺，有效提高了处理效率，降低了能耗。
基于上述研究及发现，本发明创造性地开发了一种废弃油基泥浆气驱高效除油方法和装置，具有流程简单、易操作、除油效率高、能耗低等优点，有效解决了现有技术中存在的问题。本发明处理后岩屑的含油率低至0.16％及以下，为GB4284-84《农用污泥中污染物控制标准》对矿物油最高容许含量0.3％的一半左右；岩屑在旋流器组的停留时间＜5s，因此处理时间远低于常规处理方法，实现了油基泥浆岩屑高效、低耗的无害化处理。
在本公开的第一方面，提供了一种油基泥浆岩屑旋流自转深度脱油方法，该方法包括以下步骤：
(1)体系粘度调控：通过气体介质与岩屑换热，可降低油基泥浆岩屑的粘度以减小油、水与固体颗粒表面及孔道的相互作用力，便于在旋流器组中分离；
(2)旋流自转脱油：油基泥浆岩屑颗粒在旋流器组中存在自转与公转耦合运动，利用岩屑颗粒的高速自转强化固相表面油、毛细油和孔隙油的离心脱附，利用其公转产生的周期振荡的离心力完成油气、固相的分离和富集，从而实现岩屑孔道中油相的深度脱除；以及
(3)气液分离与回用：将步骤(2)中产生的含油混合物进行气液分离，实现基础油回用、气体介质循环以及岩屑无害化处理。
在本公开中，步骤(1)的体系粘度调控过程在旋流场中进行，通过旋流场中的高速湍流流场强化气体介质与废弃油基泥浆岩屑间的换热效率，从而将液体升温实现降低其粘度的目的。
在本公开中，步骤(1)的体系粘度调控的操作温度需根据不同废弃油基泥浆配方适当选取，原则上应低于废弃油基泥浆的额定使用温度，温度范围一般为70～200℃，在此范围内，废弃油基泥浆的油相不发生裂解。
在本公开中，在步骤(2)的旋流高速自转脱油过程中，油基泥浆岩屑在旋流场中为旋流公转与颗粒自转耦合运动，自转转速最高至5000转/秒，停留时间2～10秒。
在本公开中，旋流气驱除油所使用的气体介质为空气、氮气、(超临界)二氧化碳气体、氢气、干气、低分气、天然气燃烧尾气等。
在本公开的第二方面，提供了一种油基泥浆岩屑旋流自转深度脱油装置，该装置包括：进气系统，气体加热系统，旋流器组，气液分离与回用系统，输料系统和岩屑罐，其中：
所述进气系统与气体加热系统用于对气体介质进行加热；
所述旋流器组用于对废弃油基泥浆岩屑进行旋流高速自转深度脱油；
所述气液分离与回用系统用于对旋流器溢流口流出的含油尾气进行分离循环及回用；
所述输料系统和岩屑罐用于运输和存储处理前后的废弃油基泥浆岩屑。
在本公开中，所述旋流器组为1～10级旋流器串联组合，并可根据不同处理量需求进行多级并联。
在本公开中，所述旋流器组的安装组合方式包括旋流器正装、旋流器倒装、旋流器正装与倒装组合等。
以下参看附图。
图1示出了本发明的一个优选实施方式中的油基泥浆岩屑旋流自转深度脱油方法的工艺流程。如图1所示，气体介质从进气系统1进入气体加热系统2加热后，与输料系统5-1输入的废弃油基泥浆岩屑混合并一起进入旋流器组3；旋流器组3的旋流速度场可加大气体的湍流度，强化气体介质与废弃油基泥浆岩屑颗粒间的对流传热，有利于降低废弃油基泥浆岩屑的粘度，以便颗粒的分散与油相的脱除；同时利用岩屑颗粒在旋流场中公转产生的周期振荡的离心力脱除游离油、部分毛细油，高速自转产生的离心力脱除毛细油、表面油及孔隙油，实现废弃油基泥浆岩屑的深度脱油；经深度脱油的废弃油基泥浆岩屑颗粒从旋流器组3最后一级的底流口排出，由输料系统5-2送入岩屑罐6中资源化利用，可用于井场铺路、烧砖等，而脱除得到的液相(由油、水等组成)随气体介质进入气液分离与回用系统4，气体介质返回至进气系统1循环，液相由罐车运往泥浆站回用，实现了废弃油基泥浆岩屑的无害化处理与最大化的资源重复利用。
实施例
下面结合具体的实施例进一步阐述本发明。但是，应该明白，这些实施例仅用于说明本发明而不构成对本发明范围的限制。下列实施例中未注明具体条件的试验方法，通常按照常规条件，或按照制造厂商所建议的条件。除非另有说明，所有的百分比和份数按重量计。
实施例1：
某页岩气区块油基泥浆钻井，按照本发明方法和装置进行废弃油基泥浆除油处理，其具体运作过程及效果描述如下：
1.油基泥浆岩屑样品物化性质测试
1)油、水、固三相含量测试
利用索氏提取器和CCl 4溶剂萃取废弃油基泥浆岩屑，使用红外分光光度仪测得样品的含油率为19.4％；烘干后测得样品的含固率为63.1％，含水率为17.5％。
2)岩屑颗粒粒径测试
岩屑颗粒的粒径直接影响其在旋流器中受到的离心力的大小，用激光粒度仪测得萃取后的岩屑颗粒的粒径分布如图2所示，粒径分布范围为0.15μm至976.48μm，平均直径为202.73μm，中位直径为163.49μm，标准差为226.63μm。
3)氮气吸附测试
用全自动氮气吸附仪测得萃取后的油基钻屑颗粒的比表面积与孔隙体积，如图3-4所示，颗粒平均表面积为9.43m 2/g，平均孔体积为0.0372cm 3/g，平均孔径为163.47μm。该图3-4表征了油基钻屑颗粒为表面形貌不规则的多孔体系，岩屑孔道主要在介孔范围，因此脱油非常难度大。
4)粘温曲线测试
用转子粘度计测试废弃油基泥浆液体样本在加热过程中的动力粘度变化，如图5所示，样本在加热至128℃后，继续加热粘度变化不大；而此时样本的动力粘度变化已由初温下的17500cP(厘泊)降低至226cP，降低约80倍。试验结果表明：废弃油基泥浆经过加热可以有效降低其粘度，并指导加热气体介质温度的选取。
2.实施过程
本实施例中气体介质选用的是空气，气体加热方式采用的是风道电加热器，物料输送选用的是螺杆输料机。
由进气系统以200m 3/h泵入空气，并由气体加热系统加热至160℃，输料系统以50kg/h的进料速度输送油基泥浆钻屑，气、固两相进入旋流器组进行深度脱油处理，处理后的固相进入岩屑罐，其余物质进入气液分离与回用系统；在旋流器组每一级的底流口设有取样口作为分析样本。
3.实施效果
1)脱油效果
用理论计算的方法，计算得岩屑颗粒在旋流器中的停留时间作为旋流自转脱油处理的时间，其计算结果为每级停留时间约0.3s。用索氏提取萃取-红外分光的方法，测试从各级旋流器底流口的钻屑颗粒含油率，并计算各级相对于原始物料的脱油效率。如图6所示，经过2.7s处理后，钻屑颗粒的含油率为0.16％，远低于GB 4284-84《农用污泥中污染物控制标准》中对含油率小于0.3％的要求，脱油效率达到99.2％。
2)回收泥浆性能
从气液分离与回用系统取样回收的油基泥浆，测试其性能参数如下表1所示，由结果可知，回收的油基泥浆符合重新配置油基泥浆及回用要求。
表1回收油基泥浆的性能参数
Figure PCTCN2018119278-appb-000001
3)设备能耗估算
根据试验过程能耗估算年处理量8.4万吨的工业应用装置的能耗，各主要用电设备的能耗如下表2所示：
表2设备能耗
Figure PCTCN2018119278-appb-000002
年总耗能折合标油871.78吨标油，废弃油基泥浆岩屑的处理耗能10.38kg/t标油。
综上所述，该技术的实施能有效降低工艺的运行成本，节约资源，保护环境，符合“低碳、环保、高效、节能”的可持续发展战略方向。
上述所列的实施例仅仅是本公开的较佳实施例，并非用来限定本公开的实施范围。即凡依据本申请专利范围的内容所作的等效变化和修饰，都应为本公开的技术范畴。
在本公开提及的所有文献都在本申请中引用作为参考，就如同每一篇文献被单独引用作为参考那样。此外应理解，在阅读了本公开的上述讲授内容之后，本领域技术人员可以对本公开作各种改动或修改，这些等价形式同样落于本申请所附权利要求书所限定的范围。
