摘要
高产油井一直是塔河油田缝洞型油藏的生产主力军,很多井由于含水上升导致产量快速递减。为了高效开发此类油藏,本文针对岩溶缝洞型复合油藏出水类型的多样性和生产动态的复杂性,从见水特征分析入手,以底水推进理论分析缝洞型油藏水淹预警机理,研究建立见水预警参数,从而总结出一套简单易操作的见水预警机制,使得油井的见水由“不可预报”到“可预报”,油井管理由“不可控”到“可控”;延长了高产井的无水采油期,提高了油井的可采储量。
Abstract
High-yielding wells have accounted for the mainoutputs of fractured vuggyreservoirsin theTahe Oil Field;however,productions have been decreasing quickly dueriety of water breakthrough and the complexity of production dynamicsto water breakthrough.Thevaof karst fractured vuggyreservoirs were studied.Based on the analyses of water breakthrough characteristics,with bottomflooding theory,the warning parameter and system for water breakthrough were proposed.In thiswater breakthrough in wells may be predicted,and the management of wells could be carried out.water-free production period could be prolonged and the production rate could be improved.
