| 摘 要： | 结合孤岛油田中二北Ng5稠油开发实际,分析了边底水稠油油藏水侵方式以及水侵对水驱特征曲线和油井周期生产的影响,论述了不同水侵强度对油井热采效果的影响及其产量变化规律.根据油藏工程方法,提出了应用物质平衡水驱法对水侵进行预警分析,建立了水侵预警参数方程,判断预警区水侵强度的变化,制定了分区水侵预警和治理措施,在孤岛油田中二北Ng5边底水稠油油藏开发中取得了明显效果,含水率下降0.6%,采收率提高4.4%,增加可采储量45×104t,为边底水稠油油藏开发提供了思路和方法.

| Abstract: | Water invasion way of edge and basal water and the effect of the water invasion on waterflooding pattern and oil wells periodic production were analyzed considering the heavy oil development practice in Ng5 of north Zhong2 block of Gudao Oilfield.And the thermal recovery effect and production history of oil wells in different water invaded intensity were introduced.Using one of the reservoir engineering method,material balance water-drive method was propounded for the proximity warning analysis of the water... |
