| 1. | Discussion on production decline law of gas well in sichuan gas field 四川气田气井产量递减规律探讨 |
| 2. | Diminishing marginal product 边际产量递减 |
| 3. | Factors resulting in production decline in shengping oilfield of daqing and its countermeasures 大庆升平油田产量递减率影响因素及其对策 |
| 4. | The initial production decrease degree of water injection is 0 . 0191 ( 1 / month ) 油田注水开发产量递减规律分析表明初始递减律为0 . 0191 ( 1 /月) 。 |
| 5. | Shut - in coning control is one of the methods people usually use , but it has not ideal effect 底水锥进常常使油井过早见水、含水上升迅速、产量递减加快。 |
| 6. | For waterflooding oilfields , the methods for prediction of recoverable re - serves include water drive curve , production decline , forecast model and numerical simulation 然而,当油气田业已进入递减阶段之后,产量递减法则是最为重要的预测方法。 |
| 7. | The mathematic model of automatic matching of gas - well production decline for abnormally pressured gas reservoir is developed , based on lm ' s automatic matching of production decline , combined with the regression analysis 摘要在lm产量递减自动拟合方法的基础上,结合回归分析建立了异常高压气藏气井的产量递减自动拟合数学模型。 |
| 8. | Based on this method , this paper presents the methods for quickly forecasting the technologically recoverable re - serves , economically recoverable reserves , remaining technologically recoverable reserves and remaining economically recoverable re - serves 基于产量递减法,提出了预测油气田技术可采储量、经济可采储量、剩余技术可采储量和剩余经济可采储量的快速方法。 |
| 9. | For wells with production history , the modern production decline analysis can be applied to yielding the formation parameters , and the semi - log figure of normalized time vs . normalized pressure is taken as the criterion to validate the calculated results 对具有生产记录的气井,可以采用现代产量递减分析方法反求地层参数,并用标准化时间和标准化压力半对数图,作为检验计算结果正确与否的标准。 |
| 10. | However , there are huge difficulties for keeping the production stable . the reasons are that the heavy oil accounts for 60 % of the total production , there is a lack of backup resources , high production cost and rapid decline of produc tion 而对于稠油约占总产量60的辽河油田分公司来说,由于后备资源不足,产能接替困难,原油产量结构中稠油所占比重大,生产成本高、产量递减大,要保持分公司产量的相对稳产是相当困难的。 |
