使用微粉重晶石的高密度钻井液体系在LD10-1-1井的应用

Application of micronized barite high density drilling fluid system in LD10-1-1 wells

重晶石是一种高比重的含钡矿物,具有密度高、化学性质和热学性质稳定等特点;其主要应用于领域石油工业和化工工业。在石油工业方面,其主要作为钻井液加重剂。采用粒径更小的微粉重晶石与API重晶石分别加重高密度钻井液,微粉重晶石加重钻井液的塑性黏度更低,流变性能更好,现场应用效果更好。

Barite is a high proportion of containing barium mineral,with high density,stable chemical properties and thermal properties.It is mainly used in the petroleum industry and chemical industry,as drilling fluid weighting agent. Comparison using smaller particles micronized barite and API barite add up high density drilling fluid,with the lower plastic viscosity and the better rheological properties.and the field application is better.
