怎样选准深探井钻井液密度和类型是个关键问题，当井下遇到高压盐水层、盐岩层、井壁不稳定层等复杂情况时，能否及时认识、判断和正确处理，选准钻井液密度，对安全钻井，快速钻井影响很大。深探井钻井液密度选准了，还要选准钻井液类型，使钻井液类型与油气层配伍，才能减少对油气层损害。
It is a key issue how to choose the drilling fluid density and type of deep exploration well. When the well encounters such complicated situations as high pressure saline layer, salt rock formation and unstable wall lining, can we timely recognize, judge and correct the drilling fluid density , For safety drilling, rapid drilling has a great impact. Deep well drilling fluid density selected, but also selected the type of drilling fluid, drilling fluid type and compatibility of the reservoir, in order to reduce damage to the reservoir.
