摘　　要：为了有效治理胜坨油田二区油井出砂日趋严重的状况,对沉积环境、地层压力、采液强度、生产时间进行了统计分析,得出胜二区油井的出砂规律。在此基础上实施了提高地层压力和化学防砂挡砂工艺,使胜二区地层能量逐步上升,注采比达到0.97,采液强度下降3.3t/m。同时对各种稳定剂、抑砂剂的适应性进行了评价,使油井的平均含砂量下降0.2‰,有效延长了油井免修期,减少了出砂对油田开发的影响。With statistical analysis of sedimentary environment, formation pressure, produced fluid intension and production time, sanding rules for the oil wells in the second region of Shengtuo oilfield were introduced to effectively harness the seriously sanding day by day. With the implementation of the technology on enhancing formation pressure and chemical sand control, the formation energy increased gradually, the injection-production ratio upped to 0. 97, produced fluid intension come down 3. 3t/m. With the evaluation of the a-daptability for each stabilization agents and sand inhibiter, the average sand content reduced 0. 2, the production time of the oil wells extended effectively and the influence of sanding on the development of the oilfield reduced.
