三维感应测井仪器在三维井眼环境中的正演模拟
Forward modeling of 3D induction logging tool in 3D borehole environment
摘要
Abstract
The influence of the bed boundary,borehole drilling fluid,invasion and the tool eccentricity on apparent conductivity of the three-coil array of a 3D induction well logging tool was analyzed.The results show that the apparent conductivity in the XX/YY direction can be affected more by borehole drilling fluid than the apparent conductivity in the ZZ direction.In the presence of invasion,the shift direction of the apparent XX/YY-direction conductivity is opposite to the ZZ-direction apparent conductivity.The borehole drilling fluid and invasion affect XZ/ZX-direction apparent conductivity mainly in the boundary.A decentralized tool will not affect the ZZ-direction apparent conductivity.When the tool is decentralized in the X direction,the apparent conductivity in the YY direction can be significantly distorted.But when the tool is decentralized in the Y direction,the effect on the apparent conductivity in the XX direction will be the maxmum.关键词
