| Abstract: | Storage conditions of carbonate gas zones in the Feixianguan formation are very good, both vertical and horizontal wells can yield gas at a high flow rate, blockage removal and acidizing operations conducted before production can enhance yield to a great extent. Based on analyzing geologic characteristics of gas zones in the area, the major factors affecting productivity are thoroughly examined, the versatile acidizing program for deep zones and the viscous acid sand fracturing scheme are also deeply discussed. |
