宝浪油田低渗含裂缝油藏水淹特征研究

Analysis on Waterflooding Characteristics of Low-permealbility and Fracture-bearing Reservoir in Baolang Oilfield

宝浪油田宝北区块,经过近13年的注水开发,主力层系水淹严重,地下油水关系变得越来越复杂;水淹非均质性增强,导致油田水驱波及系数低下,开发效果变差。深入研究该区油藏水淹特征,对水淹区综合治理措施的制定,提高水驱控制程度、注水波及体积,控制含水上升,改善油田开发效果有重要意义。

After 13 years injection exploration, because of serious waterflooding in the main oil-bearing strata in the north block of Baolang oilfield, the oil-water relashionship became more and more complex. Due to strongger waterflooding heterogeneities, the oiffield waterflood sweep efficiency became lower and the exploration effect became bad. Further study of the waterflooding characteristics, is significant to make the comprehensively controlling measures thus can improve the waterflooding controlling degree and injection sweep and volume, also can control water cut rising and improve exploration effect.
