聚乙烯醇(PVA)作为油井水泥降失水剂使用时,适用温度较低,难以满足高温固井的需求。通过 2-丙烯酰胺 -2- 甲基丙磺酸 (AMPS)、丙烯酰胺 (AM) 等单体,对 PVA1788 进行接枝改性,合成了一种油井水泥降失水剂——接枝改性聚乙烯醇。室内实验评价了该改性聚乙烯醇作为降失水剂使用的耐温性能、抗盐性能、流变性能、抗压强度及防气窜性能等。结果表明,加有改性 PVA 的水泥浆在 150 ℃时 API 失水可控制在 150 mL 以内;抗盐达 18%;改性PVA 明显改善了聚乙烯醇类降失水剂不抗盐的性能,稠化时间较原浆稍有延长,水泥石的抗压强度较原浆稍有提高,与其它外加剂配伍性良好,水泥浆具有很好的防气窜能力,综合性能能够满足150 ℃以下的中高温固井要求。 相似文献

Strata erosion is a widespread phenomenon in sedimentary basins.The generation,migration,and accumulation of hydrocarbon is influenced by the scale of erosion,so estimating the amount of erosion is essential in the analysis of oil and gas bearing basins.According to the geological features in the Subei Basin and the actual data,using the integrated method,we estimated the level of erosion at the unconformities caused by the Sanduo event.By using the mudstone interval transit time method and the vitrinite reflectance method on data from typical wells,it can be concluded that the Gaoyou,Jinhu,and Hongze depressions suffered strong strata erosion from the late Eocene to Oligocene,and the total strata erosion thickness was 300-1,100 m.Different tectonic units in the same depression have extremely uneven erosion intensity:the low convex regions have the maximum erosion thickness,amounting to 800-1,100 m;the slope regions have an erosion thickness of generally 600-800 m;the erosion thickness of the slope-hollow transition zone is 300-500 m.For the whole basin,we used the strata thickness trend analysis method combined with the interval transit time and vitrinite reflectance methods to estimate the erosion thickness in the Sanduo period.The results show that the most severe erosion of the Sanduo event in the Subei Basin is between 1,000 m to 1,200 m,mainly located in depressions around the Jianhu Uplift;the deep hollow area has the least erosion,generally about 300-600 m,and the erosion in the slope area is about 600-900 m.Compared with the northern part,the southern part has relatively little erosion.It is also proved that the Sanduo movement has heterogeneous intensity,and the western region has greater intensity than the eastern region. 相似文献
