水淹层综合解释方法在马厂油田的应用

The Application of Integrated Interpretation Method on Water Flooded Interval in Machang Oilfield

马厂油田进入注水开发中后期 ,由于油藏各向渗透性的差异 ,油水粘度差别及开发过程中水动力场的不平衡 ,势必造成注入水在纵向上的单层突进和平面上的舌进现象 ,油井在生产初期的主力层逐渐成为高压水淹层。利用电测和物性参数对水淹层进行定性、定量的综合解释 ,该方法确定了马厂油田的岩性、物性、电性、水淹层的评价标准 ,并在马厂油田得到充分应用。

As the waterflooded development entering into the middle & late period in Machang Oilfield, combing with difference of permeability in different directions of reservoirs, viscosity difference between oil and water, the unbalance of water dynamic area under developing condition, so some phenomenons occured, such as protruding in a certain formation on vertical section & sticking-out on horizontal plane, and initial main pay zones become high-pressure watered-out zones. This article makes a good use of qualitatively & quantitatively integrated interpretation method on waterflooded intervals with logging & formation physical parameters; determines the evaluation standards of lithological characters, physical property, electrical behavior, waterflooded interval in Machang Oilfield.
