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
