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。
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.
