1) balanced injection and production rate
注采平衡
1.
To maintain a balanced injection and production rate in ultra - low permeability reservoirs is very difficult even when applying a very high pressure water injection, due to the very fine pore throats, therefore the feasibility of gas injection should be considered.
超低渗油藏由于孔喉极细,即使高压注水,也难以保持注采平衡,应考虑注气的可行性。
2) balanceable injection-production ratio
平衡注采比
3) voidage-injection imbalane
注采不平衡
5) unbalanced injection and production
注采失衡
1.
The latter include high-pressure injection, unbalanced injection and production, well consolidation quality, perforation and repeated operation, acidification, etc.
关于油田的套管损坏原因,可以归纳为:地质因素,主要包括地应力、层间滑动、泥岩蠕变、地层塑性流变、地层出砂、断层活动等;工程技术因素,主要包括高压注水、注采失衡、固井质量、射孔和反复作业、酸化等。
6) balanced oil production
平衡采油
1.
In the process of horizontal well developing,especially the horizontal well with relative long hole interval,some problems as unbalanced oil production in each hole interval occur,which leads to bottom water and gas cap coning and limits the oil recovery.
针对水平井,尤其是长井段水平井开发过程中出现的各井段不能均衡采油,而导致底水或气顶锥进,极大影响水平井采收率的难题,结合目前现状,较为详细地阐述了水平井平衡采油的3种工艺技术:新型控液滤砂管技术、选择性采油技术和选择性射孔技术,并对这3种技术的适用范围及国内外应用情况都做了分析。
补充资料：平衡流比冲
分子式：
CAS号：
性质：按燃烧产物平衡流动条件计算出的比冲。平衡流动燃气在喷管等熵流动膨胀过程中，喷管中任意一处的燃烧产物总保持其自由能为最小，并时时处处均处于化学平衡、热平衡和速度平衡状态。平衡流比冲高于冻结流比冲，实际比冲一般处于两者之间。
