摘要
长岭地区坳陷层经历了多期构造运动的叠加改造,区内共发育4种断裂平面组合样式,中央坳陷区的乾安、黑帝庙等地区主要发育羽状直线型断裂组合;西部阶地可发育走滑断裂系形成的羽状对称型断裂组合;西部斜坡区和东部腰英台地区主要发育"入"字型、"S"字型等断裂组合。坳陷层总体发育有利的低幅度断块构造圈闭,断块圈闭又分为西部斜坡圈闭带和东部斜坡圈闭带2种类型,其圈闭演化特征是"形式相似、特征不同"。
The reservoirs in Changling Depression went through the superimposed reconstruction of multiphase tectonic movement,there developed 4 kinds of plane fault combinations.In Qianan and Heidimiao Areas of the central depression there mainly developed a pinnate linear fracture combination.In the western terrace there could develop aplume symmetrical fault combination formed by strike-slip fault system.In the western slope zone and Yaoyingtai Area in the east there mainly developed an"entering"and"S"shapes of fault combinations,etc.In the depression,there totally develop favourable and low amplitude faulted structural traps and the traps are divided into 2 types of traps such as traps in the west slope and east slope,their evolution characters are with the same shape and with different features.
