自然递减 meaning in English
infinite-acting decline
natural decline
natural depletion
Examples
- Integrated with the correlation between natural and composite decline rates as well as the characteristic of production testing data , the model for natural decline rate is established
在此基础上，结合一般油田的生产测试数据特点和自然递减率与综合递减率的关系，建立了自然递减率多因素分析模型。 - The model can be used to analyze accurately the effect of individual interrelated factor on production decline rate , support regulative countermeasures and modify the natural decline rate in an oilfield
该模型可准确地分析各相关因素对递减率的影响程度，从而为制定控制油田自然递减率的调整对策提供了依据。 - Through explaining the low - fluidity oil - deposit development structure in zaoyuan oil field , analyzing its reservoir structure and the strong flooding level hole design parameters , meanwhile adopting new techniques such as pouring water by phase control at the spot , weak point and strong plane , and so on to manage comprehensively and develop round , we have reduced the natural decrease and increased the exploitable reserves and caused the comprehensive development level of this field to rise from class 3 to class 1
摘要对枣园油田低流度油藏开展构造精细解释、相控储层结构分析和强水淹层孔隙结构参数研究，同时在现场采用相控注水、点弱面强、投球调剖和注水吞吐等开发技术进行综合治理和滚动勘探开发并举，实现减缓自然递减和增加可采储量的目的，使该油田综合开发水平由3类上升到1类。 - In order to increase prediction accuracy of development blocks with short production history , this paper introduces multiple regression method through three following aspects : prediction of decline index and initial decline rate ; prediction of annual decline rate ; prediction of injection - production ratio
为了提高生产历史较短开发区块的预测精度，从3个方面研究介绍了该方法的应用情况：一是预测递减指数和初始递减率；二是预测年对年自然递减率；三是预测油田注采比。 - At present , liaohe oilfield is in its middle and late stages of exploration and development , which means it is more difficult to keep a stable production . in recent years , a series of stimulation measures such as reperforation , water plugging and so on have been taken in different parts of the field to improve oil production and relax the natural depletion
目前，油田勘探和开发均已进入中、后期，稳产难度越来越大，为了阻止原油产量的递减，近几年辽河油田在全油区都不同程度地加大了进攻性措施的工作量，对油井采用了补层、堵水等一系列技术措施，大大的提高了油井的产量，有效的缓解了全油田产量的自然递减。
