摘要:
蒸汽辅助重力泄油(SAGD)稠油开发技术受到开发因素和地质因素的影响,其中油层厚度是影响蒸汽腔发育和蒸汽腔内部汽-水-油界面状态的重要因素。蒸汽辅助重力泄油的主要2种模型为双水平井模型和直井-水平井组合模型,文章结合辽河油田中馆陶区块的实际生产资料,运用CMG-STARS软件分别建立多井组下的概念模型,并利用控制变量法只改变油层厚度,更好地对比分析油层厚度对蒸汽辅助重力泄油开发效果的影响。在此概念模型的井组条件下,油层厚度为50 m左右,SAGD开发效果达到临界点。双水平井SAGD开发前期,厚度约为55 m时效果好; 开发后期,厚度越大效果越好。直井-水平井SAGD开发油层厚度越大效果越好,当油层厚度大于50 m时,注采效果的提升趋势相对变缓。
Abstract:
Steam assisted gravity drainage(SAGD)heavy oil development technology is influenced by development factors and geological factors, among which reservoir thickness is an important factor affecting the development of steam chamber and the state of steam, water and oil interface inside the steam chamber. The two main steam-assisted gravity drainage models are the double horizontal well model and the vertical-horizontal well combination model. In this paper, combined with the actual production data of Guantao block in Liaohe oilfield, the conceptual model under multiple well groups was established by using CMG-STARS software, and the control variable method was used only to change the single factor of reservoir thickness. The influence of reservoir thickness on the development effect of steam assisted gravity drainage was analyzed comparatively. In the case of the well group in this conceptual model, a thickness of around 50 m is a threshold for variation in the effectiveness of SAGD development. In the early stage of SAGD development, the thickness of the double horizontal well is about 55 m. In the later stage of development, the greater the thickness, the better the effect. The higher the reservoir thickness is, the better the effect is. When the reservoir thickness is more than 50 m, the improvement trend of injection and production effect becomes relatively slow.
