摘要: 利用特制的底水油藏砂岩微观孔隙模型,对底水油藏后期治理和先期堵水的负压开采进行了室内模拟试验研究。研究表明:地质体的非均质状况与底水油藏开发有密切的关系,堵剂的赋存状态与堵剂的注入时机也密切相关。在先期堵水时,堵剂多呈居中向前的"尖顶瘦扇状";而后期治理时,堵剂多呈不规则的扁平状,赋存状态不理想。开发方式、储层非均质状况和堵剂的赋存形态是影响底水油藏开发中流体渗流特征和开发效果的重要因素。后期治理和先期堵水负压开采的最终开采效果差距较大,二者最终驱油效率相差约27%。

Abstract: The indoor simulation experiment on the exploitation of bottom water reservoir was done by using the special micromodel of sandstone pore.The earlier water block-off examination and the later regulation were analyzed.The result showed that the shape of block-off agent is closely related to the injecting time of the agent.In the early stage of water block-off,the agent always locates in the middle position and going ahead in the shape of a thin fan with tine head.In the later stage of water regulation,the shape of the block-off agent always is irregular and invaluable to block off bottom water.The exploitation scheme,the heterogeneity of pore structure and the locating shape of the block-off agent are the important factors affecting the flowing characteristics and exploitation efficiency.The oil-displacement efficiency of water block-off in the early stage is higher than that of later water block-off by nearly 27%.
