为提高苯丙胶乳的适用温度，满足高温固井的需求，以苯乙烯、丙烯酸丁酯、功能单体等为原料，合成了一种新型耐高温苯丙胶乳GR ，并进行了500 kg的放大生产。室内评价了GR苯丙胶乳水泥浆体系的高温降滤失性、流变性、防气窜性能、稳定性和综合性能，对比了GR小样产品与中试产品的性能，论述了苯丙胶乳GR的作用机理。结果表明：GR苯丙胶乳水泥浆的滤失量可以控制在50 mL以下，耐温能力达到150℃；GR苯丙胶乳水泥浆具有良好的流变性、直角稠化、防气窜性能以及稳定性等特点，另外中试生产的苯丙胶乳的性能与室内小样产品均保持一致。综合分析认为，GR苯丙胶乳水泥浆可以满足150℃以下高温固井的要求。

In order to raise the applied temperature of the styrene acrylic latex and meet the needs of high-temperature cementing ,a new high temperature resistant styrene acrylic latex GR was synthesized from styrene ,butyl acrylate ,and functional monomer ,then 500 kg weight pilot product was produced .The properties(water-loss control property at high temperature ,rheology ,static gelling strength ,stability ,inte-grated engineering performances )of the cement slurry sample with styrene acrylic latex GR were evaluated then compared with that from pilot product .It shows that :fluid loss of the cement slurry with styrene a-crylic latex GR can be controlled under 50 mL ,w hile temperature tolerance is up to 150 ℃ ;It has good rhe-ology ,right-angle cementing ,good anti-channeling performance and stability ;and laboratory samples and pilot product have consistent performance .Comprehensive analysis show s that styrene acrylic latex GR can meet the requirements of cementing below 150 ℃ .
