摘　　要：针对孤岛东区稠油区块油水过渡带附近井网不完善;纵向水淹差异大,顶部动用差,储量控制程度低,以及常规完井无法转周引效的问题,建立并完善了孤岛东区普通稠油油藏的典型井地质模型,考察了原油黏度、渗透率、含油饱和度和净总比等因素对稠油化学降黏吞吐生产效果的影响,从而形成化学降黏吞吐的油藏筛选条件。依据现场不同类型油藏实施参数、效果,结合数值模拟研究,明确了稠油油藏化学降黏吞吐油藏技术界限,实现较好的开发效果。In view of the imperfect well pattern near the oil-water transition zone in Gudao East Area;In view of the large difference of longitudinal flooding,poor top production,low reserve control degree,and the inability of conventional well completion to turn the cycle into effect,the typical well geological model of Gudao common heavy oil reservoir was established and improved,and the effects of crude oil viscosity,permeability,oil saturation and net-to-total ratio on the production effect of heavy oil chemical viscosity reduction huff and puff were investigated,thus forming the reservoir screening conditions of chemical viscosity reduction huff and puff.According to the field implementation parameters and effects,combined with the physical model flooding test and numerical simulation research,the technical limits of chemical viscosity reduction and huff and puff in heavy oil reservoirs have been defined,and good development results have been achieved.
