基于倾斜发射-倾斜接收仪器结构进行随钻地质导向与地层各向异性评价
Geosteering and anisotropic resistivity evaluation by using a tilted transmitter-tilted receiver tool structure
摘要
Abstract
Starting from the sensitivity analysis of instrument's response to geological boundaries and anisotropic resistivity, a tilted-transmitter-and-tilted-receiver structure is proposed in this paper to improve directional measurement as well as anisot-ropy detection.The depth of investigation (DOI) of the tool is analyzed to evaluate the measurements'sensitivity to formation boundary in a certain environment.Inversion algorithm is also developed to achieve real-time processing of the data.As the products of the inversion application, distance to boundaries (DTB), horizontal and vertical resistivity are provided to aid in geosteering and formation evaluation.Inversion results show that the proposed structure is efficient and reliable in providing directional information, is capable of real-time derivation of relative dip angle, azimuth, formation horizontal and vertical re-sistivity inversion in arbitrary borehole environments.关键词
