摘　　要：P油田目前已进入中高含水期,实施的多口水平井用于挖潜主力水淹储层顶部剩余油,但是水平井投产初期含水和含水上升规律差异较大,影响了水平井的挖潜效果。通过分析水平井初期含水和含水上升规律,认为部分水平井的含水受附近已投产定向油井的人工压裂缝影响较大,因此,利用数值模拟软件PetrelRE中的EasyFrac模块,开展人工压裂缝对水淹层含水规律影响的相关机理研究,为油田部署水平井挖潜剩余油提供依据。At present,P oilfield has entered the middle-high water cut stage,and the multiple horizontal wells implemented are used for the remaining oil at the top of the main water-flooded layers.However,the water cut and water cut rise regularity during the initial stage are quite different,which affects the potential tapping effect.By analyzing the initial water cut and water cut rise pattern,it is believed that the water cut of some horizontal wells is greatly affected by the artificially induced fractures of nearby directional oil wells.Therefore,the EasyFrac module in the numerical simulation software PetrelRE was used for relevant mechanism on the influence of artificially induced fractures on the water cut regularity,which provides a basis for deploying horizontal wells to tap remaining oil.
