气藏水平井完井方式综合研究

Comprehensive Study of Horizontal Gas Well Completion

针对在气藏中水平井完井方式选择遇到的困难,对井壁稳定性和出砂预测进行研究,归纳影响气藏水平井完井方式选择的19种因素。考虑了多种完井方式,通过模糊数学理论消除因素量化和多因素干扰带来的影响,并结合产能评价与技术经济评价,提出一套有效的水平气井完井方式选择方法,为优选完井方式提供理论指导。

Due to the difficulties of optimizing horizontal gas well completion, wellbore stability and sand production prediction has been studied. And this paper summarizes 19 factors about optimizing the horizontal well completion in the gas reservoir.Considered a variety of completions, the impact of factor quantification and interferences between factors are eliminated by fuzzy mathematics theory, and combing deliverability evaluation and economical evaluation, the study proposes an effective method to optimize horizontal gas well completion. This method has been used in the actual production,which provides a theoretical guidance for optimizing the completions.
