随着注水开发时间的延长,葡萄花油层部分井组存在注入水主要沿高渗透层突进,导致油井含水较高、产油较低,通过开展化学浅调剖技术,可以有效地封堵高渗透层,扩大低渗透层注入水的波及体积,减缓注水井层间矛盾,实现对注水井吸水剖面的有效调整,井区连通油井受效明显,水驱开发效果得到改善。
With the extension of waterflood development time, the injection water in some well clusters of Putaohua reservoir protrudes mainly along the high permeability layer, resulting in higher water content and lower oil production. Through the chemical shallow profile control technology, the high permeability can be effectively blocked Layer, expanding the volume of water infused into the low-permeability layer and slowing the contradiction between water injection wells and realizing the effective adjustment of the water injection profile of the injection well. The connected oil well in the well area has obvious effects and the development effect of water flooding is improved.
