低渗透油田深部油藏陶粒支撑剂的现场应用

Application of Haydite Proppant in Deep Reservoir of Low Permeability Oil Field

支撑剂是水力压裂时地层被压开裂缝后,用来支撑裂缝阻止裂缝重新完全闭合的一种固体颗粒。它的作用是在裂缝中铺置排列后形成支撑裂缝,从而在储集层中形成远远高于储集层渗透率的支撑裂缝带,达到增产、增注的目的。XX油田通过在不同油层组试验陶粒支撑剂,取得良好的效果。

The proppant is a solid particle to support the cracks to prevent the cracks from completely reclosing alter hydraulicfracturing. Its role is to support the cracks to form the propped fracture zone with higher permeability. The haydite proppant has beenapplied in different oil-beating formations of an oil field, and good results have been achieved.
