潜山油藏选择性注水泥完井工艺技术研究

Application of Selective Cement Completion Tech in Buried Hill Reservoir

潜山油藏选择性注水泥完井工艺技术,在富台油田车古204-3井投入现场试验,获得成功,成为国内第一口选择性注水泥完井施工井,为进一步扩大试验井次奠定了基础。该技术实现了任意井段选择性注水泥固井,既保证固井质量,又避免水泥浆污染油层,实现了注水泥固井与油层保护的统一,满足了潜山油藏精细高效开发的需要。

The tech of selective cement completion has been developed which is applied to be exampled and gained success to be the first well's operation and establishes a foundation for the next expanding application. The tech realizes cement at arbitrary depth and not only guarantee the cement quality, but also avoids damaging oil layer of mud fluid, that achieves the unification of cement and oil layer protection to satisfy the need of fine and high efficiency development of buried hill reservoir.
