可视化水平井模型中的堵水实验研究

针对新疆陆梁油田底水薄层油藏水平井开采过程中产生的脊进现象，研制了疏水缔合聚合物有机交联体系堵水剂，并使用专门设计的可视化水平井模型对堵水剂进行模拟堵水实验，模型可观察到封堵前后的水脊情况。实验结果显示，在模拟油被采出的同时，下部底水不断入侵模拟井筒，无水采油期短且采出液含水率很快上升至75％以上。进行堵水处理后，堵剂能选择性封堵水层，对油层封堵不明显，含水率在一定时期内得到有效控制。

Water Plugging Study by 2D Visual Plate Model of Horizontal Well

A kind of hydrophobically associating polymer gel was developed as a water plugging agent toward the water coning of thin bed bottom water reservoir in Xinjiang Luliang oil field.Use this agent to run a simulated plugging experiment through an 2D visual horizontal plate model which could observe water coning process before and after the treatment.The result showed that during exploitation bottom water was getting up to the simulated well,water free production period was short and water cut increased drastic...
