产液结构调整在断块油田开发中的应用

The Application of Liquid Production Structure Adjustment in Fault-Block Oilfield Development

针对产液结构不平衡给油田开发带来的问题和影响，在对油藏进行深入分析的基础上，实施了以配套工艺为手段的产液结构调整。该文总结了胜坨油田蛇七所块沙二段3a来调整产液结构的做法，针对3类不同产液状况的油层，采用不同的排渡方式，尽量使各层段、区块门排液量趋于合理，增加了油量，减少了液量，降低了油田含水率，提高了经济效益。

For the disequilibrium of liquid production structure,the liquid production structure adjustment was carried out on the basis of analysis of the reservoir,which took the measure of matching technology. This paper sumed up the ways of adjustment at S, interval in Block Tuo 7 in Shengtuo Oilfield for three years. The different discharge fluid manners were used in 3 kinds of reservoir. So the discharge rate turned to be reasonable. The oil production was increased, the liquid production and water cut were reduced. The economic profits have been maken.
