摘要:
为明确边底水块状油藏高含水期油水运动规律及调整潜力,通过剖析典型区块陈堡油田K2t13油藏,从储层构型研究、储量动用评价、动态分析和数值模拟研究四个方面开展了剩余油分布研究。确立了适用于边底水块状油藏的产量劈分方法,在定量描述剩余油分布的同时,按成因将剩余储量分为近井物性遮挡型、井间未完全驱替型和油层内部顶部未控制型三类。研究结果表明:构型单元的分布及叠置模式与块状油藏的油水运动关联度高,油层内部顶部未控制型剩余油是下步挖潜的重点。将研究成果应用于矿场实践后收效明显,为同类型油藏剩余潜力评价与挖潜目标的制定提供了参考。
Abstract:
In order to clarify the oil and water movement laws and the adjustment potential of edge-bottom water massive reservoir in high water-cut stage, by analyzing K2t13 reservoir in CB Oilfield as a typical block, the remaining oil distribution was studied from four aspects of reservoir configuration, reservoir production evaluation, dynamic analysis and numerical simulation. A production splitting method was established, which is suitable for edge-bottom water massive reservoir. The remaining oil was quantified and divided into three types: near-well physical barrier type, inter-well incomplete flooding type and uncontrolled top type. The results show that distribution and superposition patterns of configuration units are highly correlated with the oil and water movement laws in massive reservoirs. The uncontrolled top type is the key point of potential tapping in the next step. The research results have been applied to field practice, and obtained obvious effects. It can provide a reference for evaluating the remaining potential and formulating the tapping target of similar oil reservoir.
