摘　　要：介绍了一种新型水泥浆防气窜评价方法,并采用该方法分别对胶乳水泥浆与未加胶乳水泥浆进行了防气窜性能评价,对水泥浆进行了失水量、静胶凝强度及气窜评价实验,结果表明,胶乳水泥浆具有良好的防气窜性能。将胶乳水泥浆在四川龙岗62井进行了现场应用,固井效果良好,未发生气窜,与室内气窜性能评价实验结果一致。In this paper,a new type of evaluation method of anti-migration cement slurry is introduced,and by which the perfoemances of latex cement slurry and cement slurry without latex in controlling gas migration are tested.Laboratory tests show that latex cement slurry has good anti-migration performance.The application of latex cement slurry in well Longgang-62 is successful,and the result is consistent with the anti-migration evaluation in laboratory.
