摘要
综合利用地质、地震、测井、实验分析等资料,研究费尔干纳盆地巴特肯地区的构造格局、构造演化、地层特征、油气藏类型、油气分布情况,评价其油气资源潜力。结果表明,该区在新近系前发育两条稳定的断裂,进入新近系后断裂活动强烈,发育一系列伴生断层,最终形成现今南北两隆起背斜、中间一平台的构造格局;研究区主要发育4套油气组合,侏罗系一套,白垩系三套,油气藏类型包括带油环或不带油环的凝析气藏和油藏。研究后认为,研究区石油剩余可采储量有限,而天然气具有一定的勘探潜力。
The Batken block, which was located in the southern structure edge of the Fergana Basin, had been developed in the Soviet era. Due to the technical, political, economic and other factors, its oil and gas poten- tial has not been fully excavated. In order to explore the potential, the paper studied the tectonic framework, tectonic evolutions, formation characteristics, reservoir types, oil and gas distribution, then evaluated its oil and gas resource potential and made suggestions by using of the geological and geophysical dates (such as seis- mic, logging, laborato~~ analysis, etc). It showed that the area developed two stable fractures before the Neo- gene then a series of associated fault in Neogene because of the strong fault activities, finally developed two ridge anticline located in the south and north and a platform located in the middle; which mainly developed four sets of oil gas combined, one in Jurassic, while three in Cretaceous. The reservoir types included oil res- ervoir and gas condensate with or without oil ring. Remaining recoverable reserves of oil is little but the gas reserves exploration had more potential. It suggested to explore the potential of existing wells as well as drill new wells.
