摘要
青海柴达木盆地涩北气田属第四系地层,气层埋藏浅,胶结疏松,成岩性差,在开采过程中地层易出砂,涩北气田先后进行了4口井的机械防砂、8口井的化学防砂都没有成功,通过3口井的压裂充填防砂后,产气量明显提高,且没有出砂,说明压裂充填防砂在涩北气田有一定的适应性,为今后涩北气田防砂指明了方向。
Sebei gas field in Qinghai province belongs to Quaternary formation.With gas layers buried shallowly,cemented loosely and having poor diagenetic property,the layers are prone to sand fluxing during production.In the past,mechanical sand control had been conducted in 4 wells and chemical sand control in 8 wells,which were all failed.Fracpack sand control has been conducted in 3 of these wells,the production of each well increases significantly without any sand fluxing.This shows that the method of fracpack sand control is promising in Sebei gas field.
