摘要:

大牛地气田盒1层属于低孔低渗致密气藏,主要采用裸眼封隔器分段压裂工艺进行压裂投产,取得了较好的改造效果.为了充分动用低品位气藏储量,该气田进行了水平井分段多簇压裂工艺试验探索.通过建立水平井分段多簇压裂产能模型,利用Eclipse数值模拟软件分析了影响水平井产能的地质因素及裂缝因素,同时利用正交试验设计方法对产能影响因素进行权重分析,明确了主要影响因素,进而对压裂裂缝设计参数进行了优化.现场应用效果显示分段多簇压裂工艺能够显著提高单井产量.

Abstract:

The He-1 layer of Daniudi gas field belongs to the low porosity and low permeability gas reservoir. As for this, we mainly used the packer fracturing technology in the open hole, and achieved great results. In order to make full use of the low grade gas reservoirs, the horizontal wells of this gas field has been studied by the multi-cluster fracturing technology. By establishing the model of the horizontal wells productivity with the multi-cluster fracturing and using the Eclipse numerical simulation software, the geological factors and the fracture factors that affect the productivity of the horizontal wells were analyzed. Meanwhile, the orthogonal test design method was used to analyze the weight of the influence factors of the production capacity to determine the main influence factors and then optimize the design parameters of the fracturing. The application effect showed that the multi stage fracturing significantly improved the well production.

Key words: Daniudi, horizontal well, multi-cluster fracturing, productivity influencing factor
