Fracturing technology to horizontal bare hole well, as improving low seepage gas reservoir, is used extensively in Sulige area. Taking implemented horizontal wells of Su 20 and 76 block as examples, according to the reservoir feature, from relationship of physical property of formation, fissure parameter, the included angle between fissure and hole axis, operated parameter and so on with actual reformation effect of staged fracturing to horizontal bare hole well, and then combining with theoretical analysis approach, the preliminary conclusion is formed, which will provide reference data for fracturing development to horizontal well in Sulige area. ©, 2015, Well Testing.

Acid carbonate reservoir pressure is an important means of reconstruction, but acid pressure has defects such as large acid filtration; discontinuous crack sewing; hard to form long deep closed penetration and so on. Carbonate reservoir sand-up fracturing was attempted in home and abroad research areas. Some corresponding countermeasures have been put forward through summing up the difficulty in adding sand into carbonate reservoir; strengthening transformation objective petro-physical property material research improving function of the evaluation and guidance about the small fracturing reduce fracture fluid filtration; improving the fracturing fluid efficiency and acid solution treatment + Na2C03 liquid mat technology before the Lord's lead acid fracturing; optimizing the construction technology and research the new fracturing fluid. These countermeasures have been successful applied in Dagang Oilfield in 4 Wells times and obtained good effect.
