摘要:

针对特高含水期平面剩余油分布复杂,不同区域开发对策不同的特点,提出了基于油藏数值模拟计算结果的油藏分区调控方法。首先通过极限含水率对应的含水饱和度值作为水淹区与潜力区的划分依据;其次以建立的考虑经济因素的剩余可采储量丰度界限和渗流速度界限,将潜力区进一步划分为低速新井调控区、低速注采调控区、高速新井调控区、高速注采调控区4类。综合考虑各分区分布特征,采用连通区域标记算法统计各分区连片区域网格数,计算连片区域的面积和剩余可采储量,确定不同连片区域开发政策。实际油藏的应用结果表明,调控后低速新井调控区和低速注采调控区面积大幅度减小,调控5年油藏采出程度增加3.1%。

Abstract:

Aiming at the complex planar distribution of residual oil at ultra-high water cut stage and different development strategies in various regions, a zoning regulation and control method of reservoir is proposed based on the calculated results of reservoir numerical simulation. Firstly, the water saturation corresponding to ultimate water cut is taken as the criterion to distinguish the flooded area and potential area. Secondly, the residual recoverable reserve abundance limit and flowing velocity limit are established considering economic factors. By using this two limits, the potential area is divided into four types, i.e., low-speed new-well regulation zone, low-speed injection-production regulation zone, high-speed new-well regulation zone and high-speed injection-production regulation zone. Through comprehensively considering the distribution characteristics of each zone, the connected-area labeling algorithm is used to calculate the number of grids in the connected areas of each zone. Then the area of connected areas and the residual recoverable reserve are calculated and the development policy of different connected areas is recommend. The reservoir application results shows that the area of low-speed new-well regulation zone and low-speed injection-production regulation zone is decreased greatly, and the recovery degree is improved by 3.1% after five years of reservoir regulation.

Key words: ultra-high water cut stage, zoning method, parameter limit, development strategy, enhanced oil recovery
