新站油田整体调剖试验研究

Pilot study on overall profile improvement in Xinzhan oilfield

大庆长垣西部新站油田由于储层裂缝发育, 油井见水早、含水上升快、产量递减快。裂缝没有明显主方向, 且见水井没有明显的方向性, 油田调整难度大。为改善油田的开发效果, 优选矛盾突出的区块进行整体堵缝调剖试验, 探索治理水淹井和含水上升井的有效途径, 取得了较好的增油降水效果, 整体调剖在新站油田有广阔的应用前景。

Due to the well-developed fractures in Xinzhan oilfied of west Daqing placanticline, oil wells breakthrough early, water cut rising rapidly and oil production depletes seriously. Because of uncertain principle direction of these fractures and furthermore so do the watered-out oil wells, so the adjustment is rather difficult. In order to improve the oilfield development effects, the trouble blocks are optimally chosen to conduct overall profile improving pilot test and finally to explore the valid controlling methods of watered wells and water-cut rapid rising wells. In the end much better results of oil increasing and water cut reduction have been obtained,the test stated above shows wide application prospect in Xinzhan oilfield.
