井楼油田一区边水治理对策及现场应用

Countermeasure and field application of edge water treatment in No.1 block of Jinlou oilfield

井楼油田一区属稠油油藏,储层物性好,原油粘度高,各小层有独立油水边界且边水活跃,开发过程中很容易出现边水淹现象,即使及时采取措施,也难以恢复水淹前的生产水平。针对不同水淹采取不同的治理办法,重点介绍了‘实施间开+热处理'"三线"法、"早期预防法"的具体做法和效果。三种方法现场操作简单易行、效果明显,已在其它类似区决应用。

The heavy oil pool in No.1 block of Jinlou oil field is characterized by reservoirs of excellent physical properties and crude oil of high viscosity.Each member has its independent oil-water boundary and active edge water,so it is easy to occur the edge water flooding.Even if corresponding measures are taken promptly,it is still hard to recover the production performance before the water flooding.At the principle of different treatment to different water flooding condition,the method and effect of performance partition plus heat treatment,tri-line method and early prevention method are highlighted in the paper.The three kinds of methods are easy to handle in the field and take effect in the similar blocks.
