Identification of environmental influential factors affecting LWD resistivity

Liu Zhidi,Lin Hong,Wang Ying,Xinjiang Logging Company,Karamay 834000,China  
Distinguishing the primary factors from environmental influential factors affecting logging-while-drilling resistivity is a perquisite to environmental correction.In this paper,the author summarized the environmental factors affecting LWD resistivity,and proposed to distinguish the factors by the separation between phase and amplitude resistivity curves.A workflow for identifying factors affecting LWD resistivity has been established by assimilating previous studies,and it has been verified with real data.
