        On September 21, the open hole 11th section of Horizontal Well DPH-X first built by A region of northern China with the technology of pulse plunger sanding fracturing was successfully completed. The main fracturing construction was begun at 20:20 pm. During construction, technicians from the Fracturing Technology Department paid close attention to the subtle changes in the fracturing curve and made appropriate decisions for the construction work. The fracturing construction of the 11th section was successfully completed at 1:20 on September 21, taking 30 hours, with the total sanding amount of 343m3, total fiber amount of 1650Kg, and total fluid volume of 3500m3. The entire construction process ran smoothly and was conducted basically according to the design scheme.  
 
        As the first well built with the technology of pulse plunger sanding fracturing in the working area in North Ordos, Well DPH-X was expected to make breakthrough in the output through this fracturing construction. Now, the well is opened for post-fracturing gushing. By September 21, at 10:00 am, it had released a fluid volume of 280m3. Later, we will follow closely the post-fracturing effects. 
 
        Well DPH-X was a horizontal well deployed in No. 66 Well Area in Daniu Gas Field in Ordos. The target stratum was the first section of lower Shihezi Formation. In order to improve the development effect of low permeability reservoir, the well was renovated with the technology of pulse plunger sanding fracturing. Discontinuous sanding profile was formed in artificial fractures to reduce flow resistance, to improve fracture conductivity, and to increase the effective fracture length; at the same time, in order to prevent post-fracturing sand spill, the technology of sanding with accompanied fiber was adopted in the construction process.
