摘要

针对双水平井SAGD常规蒸汽循环预热启动存在的蒸汽预热降黏慢、循环预热时间长、蒸汽消耗量大、井间动用不均衡等问题,采用室内实验和数值模拟相结合的方法,对溶剂辅助SAGD预热启动技术的原理与适用性进行了研究。研究结果表明:溶剂辅助SAGD具有缩短预热时间、减少蒸汽用量、实现井间均匀连通的效果,适用于水平段井间渗透率不小于500 mD、含油饱和度不小于60%、50℃原油黏度为2.0×10⁴~10.0×10⁴mPa·s的超稠油油藏。形成的油藏筛选条件为其他稠油油藏开展溶剂辅助SAGD启动技术提供了筛选依据。

Abstract

In order to improve the low viscosity reduction rate of steam preheating, long preheating cycle, large steam consumption, uneven interwell producing degree and other problems in the dual horizontal-well SAGD with conventional steam cycle preheating, laboratory test and numerical simulation were combined to understanding the technical principle and adaptability of solvent-assisted SAGD preheating startup technology. Research indicates that the solvent-assisted SAGD is featured by small preheating cycle, low steam consumption and uniform interwell connectivity, which is applicable for the super-heavy oil reservoirs with permeability between lateral sections not less than 500 mD, oil saturation not less than 60% and the crude oil viscosity from 2.0×10⁴ mPa·s to 10.0×10⁴ mPa·s at 50 ℃. The reservoir screening principles could provide certain reference for other heavy oil reservoirs to implement solvent-assisted SAGD startup technology.
