Description
技术领域:
本发明涉及油气田领域中反排液回收处理工艺,尤其是一种压裂反排液回收处理工艺。
背景技术:
目前随着国民经济的迅猛发展,对石油化工产品的需求越来越多,同时也对环境保护越来越重视,大庆地区每年压裂反排液至少外排3~5万立方米,反排液中的有害物质严重的污染了环境。压裂液配方主要是按不同岩石的适应性进行分类,压裂液成分可分为三大类:水基、油基、乳化压裂液。在这三种压裂液的基础上,为了适应不同井深的需要,可以将每种压裂液分为浅井、中深井、深井压裂液。以上几种压裂液的基本添加剂组分为:胍胶(稠化剂即羟丙基胍胶(Guar;Gum Cyanopsis),简称胍胶,分子量约220000,其性状为天然非离子聚糖)、粘土稳定剂、杀菌剂、消泡剂、有机硼交联剂、高温交联剂、助排剂。
根据不同地层构造和井底温度,主要是通过以上添加剂的不同配比进行配置压裂液,但基本组成不变。其中乳化压裂液主要应用于海拉尔探区,组分中多添加了一种乳化剂,其他组分基本一致。压裂液也可按温度不同进行分类,分为140℃,90℃和70℃三种压裂液,根据地层的温度不同选用不同温度的压裂液。其中的主要添加剂有:助排剂、防膨剂、杀菌剂、高温交联剂、有机硼交联剂和破胶剂。对于不同温度的压裂液,主要是通过改变以上添加剂的添加比例来达到温度上的变化。
发明内容:
为了克服背景技术的不足,本发明提供压裂反排液回收处理工艺,经该工艺处理过的压裂反排液达到国家二级排放标准或回注的目的。
本发明的技术方案是:该压裂反排液回收处理工艺,其特征在于:包括下列步骤:
(1)首先在压裂反排液中加入破胶剂进行破胶;
(2)压裂反排液破胶后加絮凝剂进行絮凝,PA絮凝剂和ZN-1助凝剂的加入量分别为3000PPm和50PPm,反应时间30min;
(2)絮凝后进行氧化,氧化时投加SYJ-2氧化剂投入量为1.5%,反应时间为3h;
(3)氧化后再进行二次絮凝,PA絮凝剂和ZN-1助凝剂投入量分别为1500PPm和30PPm,反应时间为30min;
(4)絮凝后进行二次氧化,投加RYJ-1氧化剂,为投入量为2000PPm,反应时间为4h。
本发明具有如下有益效果:本发明针对压裂反排液具体情况,实施了上述工艺步骤,经过处理后废液中COD值降为91mg/L、PH值7.5、色度/倍数总铬0.05mg/L、悬浮物5mg/L,完全达到了外排或回注要求。各工艺单元的处理温度均为常温,不需要加热处理。
附图说明:
图1氧化时间与COD去除率关系曲线;
图2强氧化剂RYJ-1的氧化时间与COD去除率关系曲线;
图3是本发明的工艺流程图。
具体实施方式:
下面结合实施例对本发明作进一步说明:
本发明所用基液采集于第二采油厂南256-斜272、南248-斜254、南198-斜260三口压裂井反排废液,均为破胶后,破胶剂为过硫酸钾,投加量为0.4%,编号分别为1、2、3号。
对废液破胶后的进行室内分析,分析结果见下表
表1
指标 | CODcrmg/L | pH | 色度/倍数 | 总铬mg/L | SSmg/L |
国家二级排放标准(石油化工) | <120 | 6~9 | <80 | <1.5 | <150 |
1号水样 | 4389 | 7.5 | 324 | 0.85 | 736 |
2号水样 | 3991 | 7.2 | 286 | 0.53 | 569 |
3号水样 | 3829 | 7.3 | 309 | 0.46 | 764 |
平均值 | 4069.6 | 7.33 | 306.33 | 0.613 | 689.23 |
由表1数据分析可以看出三个水样各项数据差别不大。
下面对上述水样进行实验室实验:
实验及分析仪器:絮凝实验装置;722分光光度计;CODGr及CODKLOH测量装置;曝气装置;搅拌装置;万分之一分析天平。
实验用药品:SYJ-2型氧化剂;RYJ-1型氧化剂;破胶剂;PA型絮凝剂聚合氯化铝铁简称复合铝铁PAFC;ZN-1型助凝剂聚丙烯酰胺(分子量在140万至160万之间);测量CODCr及CODKLOH所用化学试剂。
一、絮凝剂添加量的确定:絮凝剂最佳投加量数据见下表2。
表2
药剂投加量 | 现象 | CODcrmg/L | 色度/倍数 | 颜色 |
废液1号 | 4389 | 324 | 黄褐色 | |
PA絮凝剂1000PPm+20PPmZN-1助凝剂 | 絮体大、沉降快 | 2697 | 294 | 黄色 |
PA絮凝剂1500PPm+30PPmZN-1助凝剂 | 絮体大、沉降快 | 2015 | 236 | 黄色 |
PA絮凝剂2000PPm+40PPmZN-1助凝剂 | 絮体大、沉降快 | 1820 | 156 | 淡黄色 |
PA絮凝剂2500PPm+45PPmZN-1助凝剂 | 絮体大、沉降快 | 821 | 146 | 淡黄色 |
PA絮凝剂3000PPm+50PPmZN-1助凝剂 | 絮体大、沉降快 | 560 | 50 | 清澈透明 |
PA絮凝剂3500PPm+60PPmZN-1助凝剂 | 絮体大、沉降快 | 556 | 45 | 清澈透明 |
PA絮凝削1000PPm+20PPmZN-1助凝剂 | 絮体大、沉降快 | 550 | 45 | 清澈透明 |
由表2数据可以看出PA絮凝剂和ZN-1助凝剂最合适的投加量为3000PPm和50PPm,对COD的去除率可达到90%左右。
二、一次氧化YJ-2型氧化剂投加量的确定,YJ-2型氧化剂最佳投加量与COD去除率数据见下表3:
表3
SYJ-2型氧化剂投加量及时间 | 现象 | CODcrmg/L | 去除率% | |
废液1号絮凝后 | 清澈透明 | 560 | ||
0.5% | 3h | 有气泡及少量沉淀 | 482 | 13.92 |
1% | 3h | 有气泡及少量沉淀 | 248 | 55.71 |
1.5% | 3h | 有气泡及少量沉淀 | 220 | 60.71 |
2% | 3h | 有气泡及少量沉淀 | 217 | 61.25 |
2.5% | 3h | 有气泡及少量沉淀 | 208 | 62.86 |
3% | 3h | 有气泡及少量沉淀 | 192 | 65.71 |
由表3可以看出氧化时间3h,SYJ-2型氧化剂的最佳投加量为1.5%,对COD的去除率为60%左右。氧化时间与COD去除率之间的关系如下图1所示:由图1可以看出SYJ-2投加量为1.5%,氧化时间氧化时间为2~3h效果最佳。
三、经过破胶、絮凝、第一次氧化后COD值可降至220左右继续投加絮凝剂及助凝剂结果见下表4。
表4
药剂投加量 | 现象 | CODcrmg/L | CODcr去除率% | 色度/倍数 | 颜色 |
废液1号 | 220 | 50 | 清澈透明 | ||
PA絮凝剂1000PPm+20PPmZN-1助凝剂 | 絮体大、沉降快 | 172 | 21.82 | 30 | 清澈透明 |
PA絮凝剂1500PPm+30PPmZN-1助凝剂 | 絮体大、沉降快 | 156 | 29.09 | 25 | 清澈透明 |
PA絮凝剂2000PPm+40PPmZN-1助凝剂 | 絮体大、沉降快 | 152 | 30.91 | 25 | 清澈透明 |
PA絮凝剂2500PPm+45PPmZN-1助凝剂 | 絮体大、沉降快 | 150 | 31.82 | 25 | 清澈透明 |
PA絮凝剂3000PPm+50PPmZN-1助凝剂 | 絮体大、沉降快 | 150 | 31.82 | 25 | 清澈透明 |
由上表4可以看出PA絮凝剂和ZN-1助凝剂的最佳投加量为1500PPm和30PPm,COD的去除率可达30%左右。
四、经过以上处理后,废液中的COD值主要是由一些小分子难降解的物质形成,后期处理必需用更强一些的氧化剂,RYJ-1型氧化剂是一种超强氧化剂,投加浓度及氧化时间如下表5所示:
表5
RYJ-1型氧化剂投加量及时间 | 现象 | CODcrmg/L | 去除率% | |
废液1号絮凝后 | 清澈透明 | 156 | ||
500PPm | 4h | 先出现黄绿色后变清 | 142 | 8.97 |
1000PPm | 4h | 先出现黄绿色后变清 | 123 | 21.15 |
1500PPm | 4h | 先出现黄绿色后变清 | 108 | 30.77 |
2000PPm | 4h | 先出现黄绿色后变清 | 91 | 41.67 |
2500PPm | 4h | 先出现黄绿色后变清 | 90 | 42.31 |
3000PPm | 4h | 先出现黄绿色后变清 | 90 | 42.31 |
3500PPm | 4h | 先出现黄绿色后变清 | 85 | 45.52 |
4000PPm | 4h | 先出现黄绿色后变清 | 82 | 47.44 |
由上表5可以看出强氧化剂RYJ-1的最佳投加量是2000PPm,氧化时间为4h。强氧化剂RYJ-1的氧化时间与COD去除率关系曲线如下图2所示:由图2可以看出氧化时间4~5h能够达到最佳效果。
由上述实验得出处理工艺条件:
各工艺单元的处理温度均为常温,不需要加热处理;
1、一次絮凝投加药剂PA絮凝剂和ZN-1助凝剂分为3000PPm和50PPm,反应时间30min。
2、一次氧化投加药剂SYJ-2为1.5%反应时间为3h。
3、二次絮凝投加药剂PA絮凝剂和ZN-1助凝剂分别为1500PPm和30PPm,反应时间为30min。
4、二次氧化投加药剂RYJ-1为2000PPm,反应时间为4h。
经过处理后废液中COD值降为91mg/L、PH值7.5、色度/倍数25、总铬0.05mg/L、悬浮物5mg/L,完全达到了外排或回注要求。
五、废液经上述步骤处理后检验,检测依据《水质 化学需氧量的测定重铬酸钾法》(GB11914-89)和《高氯废水 化学需氧量的测定 碘化钾碱性高锰酸钾法》(HJ132-2003)标准,各项指标如下表6。
表6
指标 | CODcrmg/L | pH | 色度/倍数 | 总铬mg/L | SSmg/L |
国家二级排放标准(石油化工) | <120 | 6~9 | <80 | <1.5 | <150 |
1号水样 | 91 | 7.5 | 25 | 0.05 | 5 |
由以上各数据可以看出,用絮凝—氧化—絮凝—氧化后,能有效地去除反排废液中的COD,达到国家二级排放标准排放或回注的目的。
