MA Zhe,LI Jun,WANG Chao-yang,CHENG Guo-qiang (Drilling Techniques Institute, Shengli Oilfield, Dongying, Shandong 257017,China)
Measuring method and principle of TRIM (Tool Resistivity Induction MWD) system are introduced . Log application has verified in oilfield that the system can meet the requirements of measurement of direction track and geosteering combined with MWD tool and Gamma Ray tool in the later stage of oilfield development, especially in development of residual oil in thinbed. The TRIM tool can control and direct drilling track along effective formation and will be widely applied in special technological wells such as horizontal well and branch well, etc.
