塔里木盆地的上二叠统或中、新生界与下伏地层之间存在着不同类型的不整合,如褶皱削截(超覆)不整合、断块旋转削截超覆不整合、超覆不整合和平行不整合等。其中,褶皱削截(超覆)和断块旋转削截超覆不整合分布于巴楚、塔北、塔东、塔中等地,超覆不整合发育于麦盖提斜坡,平行不整合分布于塔西南-阿满坳陷。褶皱削截、断块旋转削截、超覆不整合发育区不仅生、储、盖组合好,而且运、聚、保条件佳,因而是控油意义最好的不整合,所以,塔北、塔中、巴楚、麦盖提等地是寻找不整合油气藏的有利靶区。
There are different types of unconformities in the Upper Permian or Mesozoic and Cenozoic strata and the underlying strata in the Tarim Basin, such as fold truncation (unconformity) Integration and parallel integration. Among them, folding truncation (overrun) and fault truncation rotation overcrossing unconformity are distributed in Bachu, Tabei, Tadong, Tazhong and other places. Overconformity and unconformity develop in the Maigaiti slope, Southwest Pagoda - Emman Depression. Fold cut, rotary cut block fault, unconformity overcrowded development zone is not only raw, storage, cover a good combination, and transport, poly, Paul good conditions, and therefore the meaning of oil control is the best unconformity, therefore, tower north tower Middle East, Bachu and Maigaiti are favorable targets for finding unconformity reservoirs.
