| 1. | Waterflood development is one of crucial measures for high and stable productions
摘要注水开发是保证水驱油高产和、稳产的最重要措施之一。 |
| 2. | Besides , the natural core in - house long - term washing out experiment has proved that waterflood efficiency of pressure coring can reach as high as 80 % ~ 90 %
天然岩心室内长期水冲刷实验证实了密闭取心的水驱油效率可达80 % ~ 90 % 。 |
| 3. | An onshore waterflood , on the other hand , generally involves the drilling of several injection wells and the conversion of several existing wells onto injection wells
另一方面，陆上注水方案通常要牵涉到钻几口注水井和转换几口已经存在的井为注水井。 |
| 4. | In addition , the un qualified injected water will cause the gathering and transporting systems and borehole to be corroded and will form scale in them , which will greatly reduce the waterflood effect
此外，不合格的注入水还会引起集输系统和井筒的腐蚀与结垢，从而大大降低注水效果。 |
| 5. | The proper injection allocation rate of well can effectively relieve the contradictions of plane , interlayer and inherent layers , and improve the effects of oilfield exploitation by waterflood or water drive process
合理的单井配置注量，可以有效缓解平面矛盾、层间矛盾、层内矛盾和提高水驱油田开发效果、水驱采收率。 |
| 6. | Using normal probability model is more simple and efficient to determine performance and characteristic parameter of waterflood oilfield , so it is feasible and practicable to forecast water cut and oil recovery of waterfood oilfield and evaluate its development measures
摘要应用正态概率模型可以方便地确定水驱动态变化、描述水驱特征参数，这就使得预测油田含水率、采收率、评价并发措施变得比较简便而实用。 |
| 7. | The development of this field in china was started in late 1980s . in 1988 , china institute of atomic energy in cooperation with daqing oil company conducted the first test using tritiated water as tracer for waterflood , opened the curtain of interwell radiotracer test in china
八十年代末期，中国原子能科学中国原于能科学研究院博士学位论文研究院与大庆油田合作，利用氖水作为示踪剂在国内首先开展了放射性井间示踪测试。 |
| 8. | This paper studies rock conductive mechanism through litho - electric experiment and waterflood litho - electric experiment , describes the lithology , petrophysical property and electric property of reservoir before and after watered - out , and proposes to identify watered - out zone by relative resistivity
摘要通过对岩石导电机理的研究，即岩电参数实验和水驱岩电实验，描述了水淹前后储层的岩性、物性及电性变化特征，提出电阻率相对值法识别水淹层方法。 |
| 9. | This article is mainly aim at tuo28 down reservoir of shengli oil field . through deeply analysis of geological character and its developing course . the important problems are found , first , flood pattern is not perfect , the reserivor is serious watered out in horizontal section , waterflood susceptibility is bad , the contradiction between oil and water in reservoir is serious , the interference between each producting formation is great , the crude oil is density , the reservoir have not enough energy , anisotropies is very serious . due to those facts , it is difficult to improve oil production by general technique
本文通过对胜坨油田坨28下油组油藏地质特点及开发历程的深入分析，找出目前存在的主要问题有：注采井网不完善，平面上水淹严重，注水效果差，油水矛盾突出，层间干扰严重，原油稠，油藏能量低，储层非均质性强，致使常规彩油工艺开发难度大。 |
| 10. | Based on the preferable comparability of lithology between homogeneous core used in lab lest and that in strongly water washing part of inspection wells , forming condition of displacement efficiency in strongly water washing part of pressure coring inspection wells in waterflooded area has been analyzed , and reasons for the difference of displacement efficiency between pressure coring and in - house waterflood test have been discussed
摘要基于室内实验采用的均质岩心与检查井强水洗段岩性物性较好的相似性，通过对水淹区密闭取心检查井强水洗段驱油效率形成、室内水驱油模拟条件的分析，指出了密闭取心与室内水驱油实验驱油效率差别的原因。 |
