Description
技术领域
本发明涉及一种用于石油天然气行业钻井液中作为降滤失剂的AM/AMPS-Na/MAM共聚物及制备方法。
背景技术
针对油气勘探开发向深部发展，钻遇地层越来越复杂，钻井完井所面临的困难越来越大的实际问题，国内外学者围绕超高温水基钻井液的需要，在油田用处理剂方面开展了一系列工作。重点放在丙烯酰胺类共聚物的改性，引进新的单体与丙烯酰胺共聚，制备各种降滤失剂。但合成的聚合物与超高温条件下钻井液性能维护的需要还存在差距。为此，本发明采用丙烯酰胺(AM)、2- 丙烯酰胺基-2- 甲基丙磺酸钠（AMPS-Na）和环糊精改性丙烯酰胺(MAM)等单体为原料，采用均匀设计优化配方，制备P（AM/AMPS-Na/MAM）共聚物，该共聚物作为抗高温钻井液处理剂，具有较强的降滤失作用和较好的抗温抗盐能力。
发明内容
本发明的目的是：为了克服因地层压力、温度不断升高，造成水泥浆稠化时间变短，外加剂失效，滤失量增大等不良情况，特提供一种AM/AMPS-Na/MAM共聚物及制备方法。
为达到上述目的，本发明采用以下技术方案：一种AM/AMPS-Na/MAM共聚物，其特征在于：该共聚物是由丙烯酰胺简写AM，2- 丙烯酰胺基-2- 甲基丙磺酸钠简写AMPS-Na，环糊精改性丙烯酰胺简写MAM三种单体聚合而得；所用单体的摩尔百分比及部分性能为：AM单体为83-84%，将AM用蒸馏水配成浓度为0.1g/L的水溶液；AMPS-Na为15-16%，用浓度为4.0g/L的NaOH溶液滴定2- 丙烯酰胺基-2- 甲基丙磺酸AMPS，至pH7-8，即得AMPS-Na；MAM单体1%-2%，将5.0g丙烯酰胺配成浓度为50.0g/L的水溶液，加入浓度为4.0g/L的NaOH溶液200mL，二者混合均匀后倒入三口瓶中，通入适量Cl2,进行Hofmann降解，得到部分降解后的丙烯酰胺，然后依次加入3mL环氧氯丙烷和0.5g环糊精，在80℃下反应9小时后，用无水乙醇洗涤3-5次，得絮状白色固体，于60℃烘箱中烘干即得环糊精改性丙烯酰胺单体MAM；共聚物制备中，螯合剂用乙二胺四乙酸二钠,加入量占反应单体总质量的0.25%-0.3%，氧化剂用过硫酸钾，占单体总质量的1.25%-1.5%，
还原剂用亚硫酸氢钠，占单体总质量的1.25%-1.5%。该共聚物的结构式为：
其中：X的摩尔百分比为83-84%、Y的摩尔百分比为15-16%，
符号表示环糊精结构单元。
一种AM/AMPS-Na/MAM共聚物的制备方法：AM、AMPS-Na与MAM三者的摩尔比为84:15:1，先在反应容器中加入200mL浓度为0.1g/L丙烯酰胺AM水溶液，再加入浓度为0.4g/mL的环糊精改性丙烯酰胺MAM 10mL和浓度为0.5g/mL的2- 丙烯酰胺基-2- 甲基丙磺酸钠AMPS-Na 21mL；然后往上述混合液中依次加入浓度为0.2g/L 乙二胺四乙酸二钠 0.5mL、浓度为0.5g/L的过硫酸钾氧化剂1.0mL和浓度为1.0g/L亚硫酸氢钠0.5mL；最后将上述溶液搅拌均匀后，在氮气保护下，在温度为40-50℃下反应5-6h，制得透明胶状产物AM/AMPS-Na/MAM共聚物。
与现有技术相比，本发明具有以下有益效果：⑴AM/AMPS-Na/MAM共聚物的制备方法简便可行，反应条件温和；⑵根据环糊精改性丙烯酰胺这一特性，可通过控制单体的摩尔百分比，得到具有包结、识别等性能的聚合物；⑶该方法制备的聚合物能够与钻井液中的表面活性剂等物质有机结合，作为钻井液处理剂，热稳定性能好，抗温能力强，在淡水、盐水和饱和盐水钻井液中均具有较好的降滤失作用，经过220℃高温老化后仍能较好的控制钻井液的虑矢量，体现出良好的抗温抗盐能力。
具体实施方式
下面通过实施例对本发明进一步说明。
实施例1 AM/AMPS-Na/MAM共聚物降滤失剂的制备方法
将配制好的浓度为0.1g/L丙烯酰胺AM水溶液200mL加入到500mL三口烧杯中，再加入浓度为0.4g/L环糊精改性丙烯酰胺MAM水溶液10mL、浓度为0.5g/L的2- 丙烯酰胺基-2- 甲基丙磺酸钠AMPS-Na水溶液21mL；然后再依次加入浓度为0.3g/L乙二胺四乙酸二钠螯合剂1mL、浓度为0.5g/L的过硫酸钾氧化剂1mL
和浓度为1.0g/L亚硫酸氢钠还原剂0.5mL。在磁力搅拌器上充分搅拌混和均匀后,氮气保护除氧，40-50℃下反应5-6h，得透明胶状产物AM/AMPS-Na/MAM共聚物。
按GB12005.1-89所述标准测定AM/AMPS-Na/MAM共聚物的特性粘数，再根据GB/T12005.10－92标准测定共聚物的分子量，测得AM/AMPS-Na/MAM共聚物的分子量为M＝4.43×106。
实施例2 AM/AMPS-Na/MAM共聚物的降滤失效果
为了评价AM/AMPS-Na/MAM共聚物在较高温度下的降滤失效果，首先按照GB/T16783-1997国家标准配制基浆。即在500mL去离子水中，加入2.5g无水碳酸钠、20g膨润土，高速搅拌20min后密闭静置24h，得淡水基浆。同样，在4%的淡水基浆中加入4%的NaCl，高速搅拌20min后密闭静置24h，得盐水基浆；在4%的淡水基浆中加入38%的NaCl，高速搅拌20min后密闭静置24h，得饱和盐水基浆；在500mL去离子水中，加入22.5gNaCl，2.5g无水氯化钙，6.5g六水氯化镁，75g钙膨润土以及4.5g无水碳酸钠，高速搅拌20min后密闭静置24h，得复合盐水基浆。
将样品加入基浆中，高速搅拌20分钟或在一定温度下滚动16h，用ZNS型失水仪测定钻井液的虑矢量。
表1为AM/AMPS-Na/MAM共聚物的降滤失效果。从表1可以看出，本发明的聚合物在淡水,盐水，饱和盐水和复合盐水体系中，均具有较好的抗温、抗盐和降滤失效果。
