摘要
注水和产液量加大是导致特高含水期油气生产成本上升的主要要素,如何寻找无效或低效生产层、控制无效或低效注水及产液量已成为搞好综合调整、降低油气生产成本的关键问题。因此,从理论分析、实验数据及经验值等方面分析、探讨了以累积注水倍数、数值模拟计算、吸水剖面资料、油井找水资料、注水井分层压力降落速度、精细地质研究等为依据的6种寻找无效或低效生产层的方法,并将其应用于喇嘛甸油田。实践表明,以累积注水倍数为依据,同时结合测井、试井资料,能够比较准确地判断无效或低效生产层。
Increasing water-flooding and fluid producing is the main factor that causes costs rising of oil and gas during the higher water-cut period, therefore, how to find invalid and low-effective producing intervals, to control invalid and low-effective water-flooding and producing are the key to comprehensive adjustment and lower costs of oil and gas. The paper analyzes the method from the three aspects of the theoretical analysis, experiment data and experienced value, and states six ways based on cumulative water-injected multiple, numerical simulating calculation, water absorption section data, water detection of producing well, stratified pressure drop rate of injection well, and fine geological research. These methods are used in Lamadian oilfield, and the practice shows basing on cumulative water-injected multiple and combining with logging and well testing data can judge the invalid and low-effective producing intervals accurately.
