Gas reservoir in Xujiahe Section 2 in west Sichuan are low porosity, low permeability, deep, high formation pore and fracturepressure, etc.
川西须家河组2段气藏属于低渗低孔致密深层气藏，地层压力和破裂压力高。

Especially the advantage of lowering the fracturepressure of tight sands provides a new way to develop the high fracturepressure gas reservoirs in West Sichuan.
特别是其有效降低致密砂岩地层破裂压力的特点，为川西地区高破裂压力气藏的开发提供了新的思路。

Fracturepressure is the key parameter designed for hydraulic fracturing. On the other hand, acidizing pretreatment is one of the measures reducing fracturepressure.
