| 摘 要： | 微电极曲线的负差异现象在低渗透油藏中非常普遍。从微电极测量原理入手,对微电极曲线的负差异现象进行了解释,认为原因是储层的渗透性差,泥浆的侵入非常弱,没有形成泥饼造成的;并结合压裂后试油资料,将微电极负差异现象应用于低渗透油藏储层判别中,取得了良好的效果。

| Abstract: | Abnormal negative separations of micro - electrode log curves are very common in the low permeability reservoir. According to micro-electrode log principle, the negative separation of the micro - electrode curves is explained, from which it is concluded that the causes resulting in the separations are: poor reservoir permeability, weak mud invasion and no mudcake formation. In combination with oil testing data after fracturing, the separations are used in low permeability reservoir discrimination and it has achieved good effectiveness. |
