摘　　要：克82井区在西北缘前陆冲断带挤压作用影响下,东部斜坡区发育克82井东1、2号断裂带两条逆掩推覆断裂,沿P1j2地层层间由南向北推覆,侧向推覆距离较长,对下部油气起到有效的封盖作用。该区域油源充足,断裂带处于油气优势运移范围内,P1j21-1-P1j21-2砂岩储层物性情况良好,易形成有利的构造圈闭,具有勘探价值。Under the effect of foreland extrusion,there are two overthrust nappe fault named Ke82 well no.1 east fault and Ke82 well no.2 east fault in the eastern slope zone of Ke82 wellblock.The nappe pushed long from south to north along P1j2 strata,will exert effective sealing effect on lower oil and gas.Because of its abundant oil source,advantage of oil and gas migration and good physical property of P1j21-1-P1j21-2 sandstone reservoir,the fault zone can form the valuable structural trap.
