近解远调技术在濮城油田沙三上油藏的应用

Application of the Near-Well-Bore Acidizatoin and Far-Well-Bore Adjusting Water Absorbing Profile Technique Reservoir in the Pucheng Oilfield

濮城油田沙三上油藏是一个具有多油层开发的低渗油藏 ,油藏储层在物性上表现为较强的非均质性 ,因压裂改造而产生的人造裂缝在该油藏开发初期起到了积极的作用 ,随着开发的深入 ,这些人造裂缝和非均质性地层产生的负面影响越来越严重的阻碍着油藏的进一步开发 ,近解远调技术是解决低渗油藏开发中后期的有效方法之一。

The super Es 3 resevior in the Pucheng oilfield is a set of multi-layer reservoir which represent strong heterogeneity.Man made fractures by fractured alteration have active effect in the exploitation early days.With exploitation going deep into,the negative effect by the man made fracture and strong heterogeneity do more and more severitical baffle the exploitation of oilfield.The way of the near-well-bore acidization and far-well-bore adjusting water absorbing profile techique is one of efficiency way for low penetrability reservoir in the development late days.
