摘要
塔河油田对盐下构造勘探开发过程中,固井存在封固段长、上下温差大、盐上地层破漏压力低、部分盐层井存在H2S或CO2等气侵以及盐层固井的特殊要求等问题。采用尾管悬挂固井方式与抗盐、抗高温、低失水、综合性能较好的水泥浆体系相结合的固井工艺来解决问题。现场应用表明,该固井工艺可以解决悬挂超长超重尾管和上述复杂情况下盐层固井问题。
Many problems occur in the cementing for salt bed of the Tahe oilfield, for example, long open hole, big range of temperature, low formation breakdown pressure and GC. The cementing technology which combines liner-hanger with low gravity and salt-resisting Slurry can solve poor cementing problem which above-mentioned.
