本文探讨了不同水灰比对油井水泥析水作用的影响及水灰比波动时的析水情况.还发现少量气相的存在对水泥浆的析水会有很大影响,将降低析水作用或引起分段析水。
This paper discusses the effects of different water-cement ratios on the water-extraction effect of oil-well cements and the water-splitting conditions when the water-cement ratio fluctuates. It is also found that the presence of a small amount of gas-phase has a great influence on the precipitation of cement slurries, which will reduce the effect of water precipitation or Caused segmental water analysis.
