摘要
低渗透油藏由于储层物性差,渗流能力差,油井普遍低产低效,如何提高单井产量是低渗透油藏面临的难题,因此为探索低渗透油藏提高单井产量的有效手段,开展了混合水体积压裂新工艺试验,通过现场应用取得了重大突破,有效增大了泄油面积,提高了单井产能,本文主要从该工艺特点、适用条件及实施效果进行总结评价,旨在进一步探索低渗透油藏提高单井产量的新途径。
Low permeability reservoirs due to reservoir physical property is poor, the seepage ability is poor, the well is generally low, how the bill of lading the difficulties faced by single well production is low permeability reservoirs, thus to explore the effective means to increase the single well output low permeability oil reservoirs, the fracturing technology experiment was carried out by mixing water volume, through the field application has achieved a break-through, effectively increasing the drainage area, improve the single well productivity, this article mainly from the summary on the process features, applicable conditions and effect evaluation, aims to further explore the new way to increase the single well production of low permeability oil reservoirs.
