摘要
通过实验研究了吐哈油田鄯善和丘陵两区块注水堵塞机理。结果表明, 两区块注水堵塞主要是岩层敏感性、油层内颗粒运移、注水管线腐蚀、注入水不溶物高和细菌含量高等原因所引起的。
The plugging mechanism during water injection in two blocks of Shanshan and Qiuling of Tuha oilfield is studied in lab.It is mainly resulted from layer sensitivity,particle migration within the oil layers,erosion of water injection pipeline,high-content insoluble material in the injected water,high-content microbes etc.
