地质与压裂一体化布井技术在苏里格气田的应用

苏里格气田是形成于河流相背景下的低渗透致密砂岩气藏,沉积条件和储层物性决定了其开发难度大,水平井整体部署技术和压裂技术的结合应用可实现气田的少井高产高效开发。从水平井部署的地质依据出发,以综合经济效益为目标,对井网、井距、水平段长度、方位、井眼位置、压裂缝长、压裂规模等方面进行了优化并应用,在苏53区块取得了良好的开发效果。

Application of integrated well spacing technology between geology and fracturing in Sulige gas field

Sulige gas field was formed in the low permeability of fluvial background under tight sandstone gas reservoirs,the deposition conditions and reservoir properties determine its development difficulty is great.Combined with the overall deployment of horizontal wells and fracturing technology,high efficient and high-yielding gas field development has been achieved.Starting from the geological guidance of horizontal wells deployment,by taking as the overall economic efficiency as the target,the optimization and application of well spacing,horizontal length,orientation,wellbore position,the pressure fracture length,fracture size and other aspects have been carried out.In the end,agood development result has been achieved in Su-53 block.
