The styrene-butadiene latex cement slurry system can help to raise the elasticity and toughness of oil well cement sheath. 丁苯胶乳水泥浆体系有利于提高油井水泥环的弹性和韧性。
On the basis of the simplified model, the effect of the cement annulus thickness and the cement resistivity on resistivity log through casing are analysed. 并在此基础上，分析了水泥环厚度和水泥电阻率这样两个因素对过套管电阻率测井的影响。
