摘　　要：随着井深的增加,对压井液耐温能力的要求也更为严格。油田目前普遍应用的压井液体系耐温能力差并且对储层伤害大。结合实际,研究了耐高温高密度压井液体系,密度1.85g/cm3,242℃高温前后表观粘度均不超过110mPa.s,滤失量均在8.0ml(API)之内。The temperature tolerance of control fluid is more and more important along with the in- creasing of well depth. The control fluid applied in Oilfield shows poor temperature tolerance and huge reservoir damage. Here is a complete research on the control fluid system with high temperature resistant and high density,density 1.85 g/cms, apparent viscosity not exceeding 110m_Pa, s at 242℃, API permeability is less than 8.
