Y7侏罗系油藏精细描述及开发技术研究

Y7 Jurassic reservoir fine description and development technology research

Y7油藏该区开发始于2014年,相比侏罗系同类油藏,储层物性相当,但目前压力保持水平低、水驱动用程度低、早期单井产量低,亟需深入开展储层特征研究、开发技术政策评价,为油藏持续稳产提供技术支撑。本文通过对研究区进行精细油藏描述,深化储层认识,开展单井产能受控因素研究,利用数值模拟、油藏工程、同类油藏对比法,确定适应油藏开发早期阶段的开发技术政策,为油藏高效开发奠定基础。

The Y7 reservoir development began in 2014, compared to similar reservoirs ofJurassic, reservoir, but the pressure to maintain the low level, low producing degree of waterflooding, the early low single well production, to carry out the research on the reservoir char-acteristics and development technology policy evaluation, sustainable development to providetechnical support for reservoir. Based on the study area of fine reservoir description, deepenthe understanding of reservoir, to carry out the research on the productivity of single wellcontrolled factors, using numerical simulation, reservoir engineering, oil reservoir in contrast,determined to adapt to the development of technology policy in early stage of reservoir devel-opment, the basis for the efficient development of reservoir.
