准噶尔盆地排6区块浅层稠油实用勘探技术
|
摘要
排6区块位于准噶尔盆地西缘车排子地区,曾因油层薄、油稠而放缓了勘探步伐。借鉴排2块勘探的成功经验,采集高精度的三维地震资料,应用地震拓频处理等新的解释技术,对排6区块油气源、油气输导体系、油气成藏期次及沉积体系进行研究,明确了油气来源,证实了油气输导通道,发现了2期成藏的特点,为储层预测提供了理论依据。在此基础上,部署探井和滚动井22口,成功20口。
The Pai 6 block is located in the Chepaizi area in west Junggar Basin,where exploration progress has been slow due to thin reservoir and heavy oil property. Based on the successful experience of exploration in the Pai 2 block,this paper studies the Pai 6 block in respects of oil sources,hydrocarbon transport system,accumulation period and sedimentary system by using high-precision 3D seismic data and new interpretation techniques such as frequency-extended processing. The oil sources and transporting pathway are defined. Two phases of hydrocarbon accumulation are recognized. 22 exploratory and progressive wells have been deployed on the basis of this study and 20 of them are successful.
