摘要
利用水平井开发气藏 ,是提高气井产能 ,改善开发效果的重要手段。一般而言 ,水平井的水平段越长 ,产能就越高 ;但是产能的增加与水平段长度的延伸并非线性关系。因此在气藏水平井优化设计中研究的首要问题就是确定最优的水平段长度 ,从而以较少的投入 ,获得最好的效益。本文利用气井产能评价资料 ,根据气藏水平井产能评价的常规气藏工程方法 ,结合实例研究了水平井不同水平段长度与气井产能的关系 ,并通过综合分析 ,为优化水平井合理的水平段长度提供了依据。
It is an important means for raising gas well productivity and improving development results to make use of horizontal well to exploit the gas reservoir.Generally,the longer the horizontal interval of the gas well,the higher the productivity;and the increase,however,of the productivity isn′t a linear relation to the lenth of the horizontal interval.Therefore the problem which should be firstly studied in optimizing horizontal well design of the gas reservoir is to determine the optimum length of the horizontal interval so as to achieve best returns with less input.By use of the gas well productivity data and according to the conventional gas reservoir engineering methods,the relation between the length of horizontal interval and the gas well productivity was studied and comprehensively analyzed in combination with a case,thus providing basis for optimizing the length of horizontal interval.
