摘　　要：孤岛油田南区稠油地质储量2271.6×104t,"多、薄、断、差"等油藏特点决定开发管理难度大,目前采出程度仅有5.3%,采收率仅有11.3%,具有挖潜增效的丰厚物质基础。为此对南区馆上段5-6砂层组(Ng5上-6)、馆上段1+2～4砂层组(Ng1上+2～4)稠油开展了分类分层系精细地质研究,实施配套的开发调整技术:井网控制程度高的中部Ng5-上6稠油进行储层及流体非均质性精细评价,实施细分层系、低效水驱转热采调整;井网控制程度差、构造复杂的边部Ng1上+2～4稠油进行构造解释和储层反演,落实资源,层系立体开发调整。达到提高其储量动用程度、改善开发效果、提高采收率的目的,从而实现孤岛南区稠油的高效开发。The geological reserves of south Gudao Oilfield were 2271.6×104t,it's reservoir characters were multilayer,thin reservoir,fault zones and poor reservoirs,which determined that it was difficult for oilfield management and development.At present,the recovery percent was only 5.3%,recovery ratio was 11.3%,it had a good foundation for tapping the potential.Fine geological research was conducted on Layers Ng5-6 and Ng1+2～4for implementing supporting adjustment techniques,for the highly controlled well pattern of middle Ng5-6 heavy oil layer,a fine evaluation was performed on the heterogeneity of reservoirs and fluids to implement sub-zoning and low efficient waterflooding transferred to thermal recovery,for Ng1+2～4 heavy-oil layer with poor well pattern control and complex structure,structural and reverse reservoir interpretations were carried out to clarify the resources and adjust the strata development for the purpose of raising the oil porduction level of reserves.Improving the development effect and enhancing oil recovery and for effective development of the south Gudao Oilfield.
