摘要
根据2001年7月完成的“准噶尔盆地构造格架综合工程探测”报告中“额敏—克拉玛依—奇台人工地震测深横剖面”资料,进行地质解释和深入探讨,提出克—乌油区油源不在传统观念的玛湖坳陷,而是在克拉玛依—扎依尔山地下28～38km深处的中、下地壳内。油气是靠油源层东、西两侧超壳深大断裂和众多的推覆体逆掩断裂运移到克—乌油区上来的,油源中有海相和陆相沉积物中有机质参加和贡献。这已被乌尔禾沥青脉和油、气、水、岩心等分析资料所佐证;克—乌油区油气藏展布特征、地面油气苗分布特征也都显示应主要是垂直运移的结果。据此提出了进一步深化勘探克拉玛依油田的设想和建议。
Geological interpretation and thorough research are carried out based on the data of 'the deep artificial seismic sounding profiles of Emin-Karamay-Qitai' in the report of 'the integrated engineering detection of the structural framework of Junggar Basin' accomplished in July 2001.In this paper,the author puts forward that the oil source of Karamy-Urumqi oil province does not lies in Mahu Depression but in the middle and lower crust 28-38km below Karamay-Zhayier Mountains.Based on the data analysis of the bitumen from Wuerhe,oil,gas,water,and cores,it is proved that oil and gas are migrated to Karamay-Urumqi oil province through the supracrustal and discordogenic fault and numerous nappe thrusts on the east and west sides of the oil source bed,in which the oil sources contain plenty of organic matters from marine and terrestrial sediments.The distribution characteristics of various reservoirs and oil-gas seepages of Karamay-Urumqi oil province also show that the oil sources of the oil province are vertically migrated.Suggestions are put forward in this paper to promote the exploration oil in Karamay Oilfield.
