Foam leaking stoppage slurry, preparation method of foam leaking stoppage slurry, foam leaking stoppage slurry system and application of foam leaking stoppage slurry system
The invention relates to the field of oil drilling, and discloses foam leaking stoppage slurry, a preparation method of the foam leaking stoppage slurry, a foam leaking stoppage slurry system and application, the foam leaking stoppage slurry comprises cement-based slurry, a foaming agent and filled nitrogen; wherein relative to 100 parts by weight of the cement-based slurry, the foaming agent is not more than 5 parts by weight; the filled nitrogen is metered by volume, and the amount of the added nitrogen meets the requirement that the density of the foam leaking stoppage slurry is reduced by 3-30% compared with that of cement-based slurry. The density of the foam leaking stoppage slurry can be flexibly adjusted according to the inflation proportion, and the foam leaking stoppage slurry is suitable for variable leakage well conditions on site.
本发明涉及石油钻探领域，公开了一种泡沫堵漏浆及泡沫堵漏浆的制备方法、泡沫堵漏浆体系及应用，所述泡沫堵漏浆包括：水泥基浆、泡沫剂和填充的氮气；其中，相对于100重量份的水泥基浆，所述泡沫剂为不大于5重量份；所述填充的氮气以体积量计，加入的氮气量满足所述泡沫堵漏浆的密度相比于水泥基浆下降了3‑30％。本发明所述的泡沫堵漏浆根据充气比例能够灵活调节密度，适用于现场多变的漏失井况。
