摘　　要：我国东部油田已普遍进入高含水开发阶段,因此,以剩余油形成的主要地质控制因素为线索,深化油藏开发地质研究已成为研究的重点。以胜利油区高含水油田为例,在低级序构造、储层精细刻画和剩余油定量描述等开发地质研究方面取得了明显进展。陆相水驱油藏剩余油富集区主要受低级序断层、夹层和物性差异等油藏非均质性的控制,因而重点形成了低级序断层精细描述与预测、河流相储层构型、夹层描述与预测、储层优势通道描述与预测等先进技术,并且建立了分割性约束的精细数值模拟模型,增加了空间流体拟合条件,使得剩余油富集区的定量描述更加符合油藏实际动态。Most oilfields in the eastern China have entered the high water-cut stage of oilfield development. The research of oilfield development geology focuses on the geological controlling factors of the remaining oil at present. Taking Shengli Oilfield as an example, the remaining oil of this oilfield was controlled by the reservoir heterogeneity factors such as low-grade fault, interbed and the reservoir property. So, the key technologies including the description and prediction of low-grade fault, the fluvial reservoir architecture and interbed, and the superiority flow channel of reservoir were developed. The fine digital simulation model was established, and the 3D fluid fitting conditions were presented. The description of remaining oil is more agreeable to the dynamic situation of oilfield.
