摘要:
随着海上油气田开发的不断深化,水平井技术已在增储上产中起到了巨大作用,但也面临着出水及含水不断升高的问题。进行水平段储层生产测井,确定井下层内生产情况及储层动用情况,是后期控水稳产、措施挖潜的关键。水平井因井眼轨迹与储层平行、流体重力分异明显、上/下坡流共存等因素,常规居中测量中心流速的测井技术已不适用;同时,水平井为单层开采,剩余油饱和度分布无标准水层刻度,为生产层剩余油分布监测提出了挑战。提出了阵列式多相流测井仪组合(MAPS)和剩余油饱和度测井技术(RPM)的组合测井方式,通过水平段截面速度剖面、流体性质分布以及剩余油饱和度分布三者间的相互验证、综合解释的解决方案,取得了良好效果。

Abstract: The horizontal wells play a significance role in increasing yield with continuous deepening of oil and gas development in offshore oilfields. However, it faced the problems such as water produc-tion and continuous increase of water cut etc. In order to stabilize yield and hold water cut, it was a key measure for water control, stabilizing production and tapping the potential at the late stage by conducting production logging in horizontal section and determining the production and reservoir drainage of each layer. The horizontal section, which was parallel to the reservoir, had an obvious gravity differentiation, upslope and downslope flow coexist at the same cross-section; these cases make the traditional centralized velocity survey unsuitable. At the same time, the horizontal section usually ran through one single layer, and there was no standard water-bear layer for calibration, which constrained the monitor of distribution of residual oil saturation. To solve these problems, this paper intends to propose a new combined logging method, which is the makeup of multi-phase array tools (MAPS) and reservoir performance monitor tools (RPM). By obtaining and corroborating the velocity profile in horizontal section, the oil-water distribution and residual oil saturation distribution, a comprehensive interpretation solution is achieved a good effect is obtained.
