The invasion of drilling fluid is the main cause to the damage of fractured formation. The composite salt free-gel drilling fluid is got after analyzing the influence of different kinds of such soluble adulterant as organic salt and non organic salt on the performance of the solid-free drilling fluid and studying the condition to develop the free gel structure and the method to improve the fluid's high temperature stability and inhibitive property. The experiment shows that the apparent viscosity of this system is as high as 27000 mPas when the share rate is 0.3 r/min and the high temperature reaches at the stable level of 150℃ and the HTHP filtrate loss decreases to 15 ml at 150℃.

Kangdai Ⅰ has protective function to the damaged neurons and astrocytes: Main results:(1) It has direct protective function to the damaged neurons. It can increase the activity and survival rate, decrease the mortality and the transudation rate of LDH in cultured medium and the strong positive cell count of NOS expression of injured neurons.(2) It has also directly protective function to the damaged astrocytes. It can increase the activity and survival rate and protein content in conditioned medium.(3) It can strengthen the ability of BDNF, GDNF, bFGF, HSP and IL-6expression in damaged astrocytes.(4) It can also strengthen obviously the expressions of NSE, bFGF-receptor and bc1-2, lower the expression of bax and caspase-3.(5) It can indirectly protect and restore the damaged neurons by astrocytes. Because the effect of ACMK (ACM interfered by Kangdai Ⅰ) is stronger than ACM+K (ACM associated with Kangdai Ⅰ).

抗呆Ⅰ号对受损的神经元和星形胶质细胞均具有保护作用:主要表现为:(1)对受损神经元具有直接的保护作用,可提高受损神经元的活性和存活率,降低细胞培养液LDH的漏出率、细胞死亡率和NOS染色强阳性细胞的表达量;(2)对受损的星形胶质细胞也有直接的保护作用,可提高其活性、存活率以及培养液蛋白质的含量;(3)能增强受损星形胶质细胞分泌BDNF、GDNF、bFGF、HSP和IL-6的能力;(4)可明显增强受损神经元对NSE、bFGF的受体和bc1-2的表达,降低受损神经元对bax和caspase-3的表达;(5)抗呆Ⅰ号可通过星形胶质细胞间接地保护和修复受损的神经元,因为在多数实验组中经抗呆Ⅰ号作用的ACM的作用远大于ACM与抗呆Ⅰ号联合应用的作用,统计学上具有显著性差异。
