摘要
LD气田属于典型的低渗致密气藏,储层非均性强、含气丰度低、展布规模小,稳产难度大。分析了LD气田压裂改造存在的问题,提出了相应的压裂改造关键技术,并分析了应用效果,这些技术包括不动管柱多层压裂技术、水力喷射压裂技术、低伤害压裂技术。这些技术提高了LD气田低效气井开发效果。
LD gas field is a typical gas reservoir with low permea-bility,strong heterogeneity,low gas-bearing abundance,small-scale in distribution and great difficulty in stable gas production. Therefore,the difficulties and countermeasures of fracture technology have been analyzed and put forward in this paper,which includes fixed-column multi-fracturing,hydraulic fracturing jet-tech and low damage fracturing technology. The technology in practice has achieved good application effect and will provide guidance for low-efficien-cy gas wells development of LD gas field.
