F油田属于开发20余年的“低孔、低渗”的老油田，目前相当一大部分井已进入高含水期，使得油田稳产压力大。通过对该油田的高含水井及明水井见水原因的分析，发现油井见水的主要原因为异层水影响、底水锥进、注入水影响三个类型，并通过实践，采取了微膨胀水泥封堵、有机凝胶化学堵水、体积压裂等措施，效果较好。%F oilfield belongs to the “low porosity and low permeability” of old oilfield that has developed for more than 20 years, and a relatively-large portion of wells in this oilfield have developed into the high water-cut stage that strengthens the pressure of oil production stability. Through the analysis of water breakthrough reasons for high water-cut stage wells and open water wells, three reasons that include influence of water in different layers, bottom water coning and injection water are found. And through prac-tice, to carry out a micro expansive cement plugging, organic gel chemical water plugging, volume fracturing and other measures are found to be acquire effective effects.
