摘　　要：多元热流体技术是海上稠油高效开发的关键技术,在渤海油田开发中得到了广泛应用,但当边底水油藏存在大孔道时,水窜将严重影响开发效果。针对此问题,以渤海S油田油藏特点为基础,开展大孔道的长度、大孔道渗透率倍数、大孔道位置及生产井距边底水距离对水窜规律影响的研究,研究表明:大孔道长度、渗透率倍数及生产井距边底水的距离与水窜时机、周期末含水率、水窜程度呈正相关,大孔道的相对位置不同时,其水窜规律也有所差异。Multi-component thermal fluid technology is the key technology for the efficient development of offshore heavy oil.It has been widely used in the development of Bohai oilfield.However,water channeling becomes serious with the existence of large pore path in the reservoir,strongly affecting the oil well normal production.To solve this problem,based on reservoir characteristics of oilfield S in Bohai.To carry out the large pore path length,permeability multiple,location between oil well and bottom water of the influence on water channeling law.Results show that large pore path length,permeability multiple and the distance between oil well and bottom water are directly proportional to water channeling severity and timing.While the different relative locations of large pore path to the production well result in difference in water channeling law.
