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 prot ruding 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 , elect rical behavior , waterflooded interval in Machang Oilfield.
