| 摘 要： | 实验室测试钻井液的API失水量结束后，仪器内剩余钻井液的粘度比测试前有所增大。为了解释这一现象，对原钻井液静失水量方程推导中所采用的渗滤模式提出了不同看法，以一种不同的渗滤模式为基础提出了新的钻井液静失水量方程，此方程可以解释这一现象。依照此方程，实验室测试API失水量时仍然可用7.5 min失水量的测试结果乘以2得到的数值代替30 min失水量的测试结果。

| Abstract: | It is found out that the viscosity of the remaining drilling fluid is higher than before the API loss test was taken. To explain this phenomenon, the paper presents a different opinion about the filtration mode used in the derivation of equation for calculation of static loss of drilling fluid, and derived a new equation based on a new filtration mode, which can explain the phenomenon. According to this new equation, twice of the result of 7.5 min test can replace that of the 30 min test in the API loss test. |
