Cement blanket for oil field
The invention discloses a cement blanket for an oil field, and belongs to the technical field of cement blanket processing. The cement blanket for the oil field is used for solving the technical problems that in the prior art, concrete components in an oil field cement blanket are large in loss in the construction process, the watering hardening effect of the cement blanket is poor, and the fire resistance of the cement blanket needs to be further improved. The reinforcing layer is prepared by dipping a fiber layer in modified concrete; the preparation method of the modified concrete comprises the following operation steps: adding the cement and the fine aggregate into a drying box at the temperature of 80-90 DEG C, drying for 10-12 hours, then adding into a beaker, and uniformly mixing to obtain a sediment mixture. According to the invention, the loss of a silt mixture in the cement blanket in the construction process can be effectively reduced, the compressive strength and breaking strength of the cured cement blanket are ensured, and the high temperature resistance and freeze thawing resistance of the cement blanket are also effectively improved.
本发明公开了油田用水泥毯,属于水泥毯加工技术领域。本发明用于解决现有技术油田水泥毯中的混凝土组分在施工过程中存在流失较大,水泥毯浇水硬化效果不好和水泥毯的耐火性能有待进一步提高的技术问题,油田用水泥毯,包括自下而上依次设置的控水层、加强层与透水层,所述加强层由纤维层浸渍改性混凝土后制备而成;所述改性混凝土的制备包括以下操作步骤:将水泥、细骨料加入到温度为80‑90℃的干燥箱中,干燥10‑12h,然后加入到烧杯中混合均匀,得到泥沙混合物。本发明不仅能够有效的降低水泥毯中的泥沙混合物在施工过程中的流失,保证水泥毯固化后的抗压强度与抗折强度,还有效地提高了水泥毯的耐高温性能与耐冻融性能。
