Abstract: To find out the new approach to increasing single well production and recovery in low-permeability gas reservoir, through conducting research on the horizontal well fracturing technology currently used both home and abroad, the open hole completion multistage fracturing technology is proposed to be applied in Sulige gas field, and it is tested in Suping 36-6-23 well. Through staged fracturing, open hole staged fracturing commingled drain is realized in this well, the open low is tested at 101.4764×104 m3/d. So this well becomes the first one with open flow exceeding one million cubic meters in Sulige gas field. It provides a reliable completion technology and stimulation approach for the development of horizontal wells in Sulige gas field.
