| 摘 要： | 窟窿山逆掩推覆带位于酒泉盆地祁连山北缘西部,中生代为断陷盆地，新生代为前陆盆地，已在窟窿山构造发现青西裂缝性油藏。为了搞清油气富集特征，以断裂构造剖析为主线,对本区逆掩推覆带内的撕裂断层在油气成藏中的作用进行了探讨。剖析了窟窿山地区油气分布的独特特征,指出北东向撕裂断层控制着开启性裂缝带的分布，是油田的高产区块。

| Abstract: | Kulongshan overthrust nappe is located in west of nothern margin of Qilíanshan mountain. It is a faulted basin in Mesozoicand a foreland in Cenozoic. In its Qingxi depression is found fractured reservoirs, In order to make elear the oil-gas enrichment , this paperdiscusses the effect of tearing faults in overthrust nappe on oil-gas accumulation by means of the analysis of structural faults and theirdistinct oil-gas distribution. ht is pointed out thal il is N-E tearing fault that controls the distribution of open frachral bel, which could behigh-yielding block. |
