| 摘 要： | 通过钻井液动态侵入的3种过程分析钻井液侵入储层的机理及影响因素，根据达西定律，描述了泥浆侵入的基本特征。实例说明，钻井液动态侵入造成油气层低阻，使测井响应趋于复杂化。

| Abstract: | The effect of drilling fluid to reservoirs is divided into three mode.The characteristics of hydrocarbon bearing formation invaded by mud filtrate were analyzed based on Darcy′s law. Theoretical study and real examples show that low resistivity formation is resulted from the dynamic invasion of drilling fluid, which makes responses of well logging complicated. |
| |
| Keywords: | drilling-fluid permeable formation response to drilling-fluid well-logging response |
