摘　　要：针对卫 79断块属高压低渗油藏 ,储层物性差、孔喉半径小、注水压力高、注水效果差、地层亏空严重、能量不足 ,导致油井普遍供液不足、提液困难大、产量递减快的现状 ,提出了六种新的油层解堵工艺技术 ,通过多元解堵工艺的综合实施 ,使油藏开发指标得到较大改善 。Wei79 fault block is a high pressure and low permeability reservoir.It is featured as poor reservoir physical property,small pore throat radius,high water injection pressure,poor water injection results,serious formation voidage,and not enouht energy,which lead to fluid supply not enough,and rapid production reducing.So the paper presents 6 new plug removal techniques.By using of multivariate plug removal technique,reservoir development indexes have been better improved.So it is a new comprehensive method for maturing period development of high pressure and low permeability reservoir.
