Development and Field Application of a New High-Temperature Cement Suspension Agent
-
摘要: 针对深井井下温度高、水泥浆沉降稳定性难以保证的问题,研制了共聚物水泥悬浮剂。选用2-丙烯酰胺基-2-甲基丙磺酸(AMPS)、丙烯酰胺(AM)和N-乙烯基吡咯烷酮(NVP)为共聚单体,采用自由基水溶液聚合法,合成了三元共聚物(AMPS/AM/NVP)水泥悬浮剂,并根据正交试验结果,确定了其最佳合成条件。利用红外光谱和核磁共振谱分析验证了其结构,热分析结果表明其具有较好的热稳定性。性能评价试验表明,合成的共聚物悬浮剂在200℃下能够控制水泥石上下密度差小于0.01 g/cm3、游离液为0,且抗饱和盐水,稠化性能、滤失性、流变性、强度等性能均满足现场要求。3口井的现场试验表明,新型抗高温水泥悬浮剂可以提高深井固井施工安全和固井质量。Abstract: In this paper, a copolymer cement suspension agent was developed in order to solve problems found in deep wells, such as high temperature and settlement stability of cementing slurry. The terpolymer (AMPS/AM/NVP) cement suspension agent was synthesized with 2-acrylamido-2-methylpropane sulfonic acid (AMPS), acrylamide (AM) and N-vinyl-2-pyrrolidone (NVP) as comonomers by means of free-radical aqueous solution polymerization. And its optimum synthesis conditions were confirmed on the basis of orthogonal test results. Its structure was analyzed by means of infrared spectrum analysis and nuclear magnetic resonance spectroscopy. Based on thermal analysis, it was thermally stable. Further, it was demonstrated by performance test results that based on this copolymer suspension agent, that the settlement stability of cement slurry at 200℃ could be kept below 0.01 g/cm3, with free fluid 0. Further, there was enhanced saturated brine tolerance. The new copolymer suspension agent could meet field requirements comprehensively in terms of thickening, filtration, rheological behavior and strength. It was demonstrated by field tests of three wells that this kind of new high-temperature cement suspension agent played an effective role in improving the safety and quality of cementing operations in deep wells.
