Application of Trend-Surface Analysis to Fault Recognition in Yingmai-2 Well Area in Tabei Area,
///Yingmai-2 structure of Tabei area in Tarim Basin is a dome anticline, characterized by complex structure, multistage and multi-grade faults. The identification and explanation of the faults are difficult due to high dip of strata. In this paper, the trend-surface analysis technique is applied to the identification of the faults, and the faults distribution in the area is described.
