压裂充填防砂工艺技术

Sand Control Technology of Fracturing Filling

胜利油田和辽河油田松散砂岩油藏开发良好。自20世纪60年代以来,这些油田一直致力于研究各种防砂方法。机械防砂和化学防砂均可在一定时间内控制地层砂的产量,但代价是气井的部分生产能力。实施一些工序后,产量减少70%~80%,不利于油气田的快速发展。

The loose sandstone reservoirs in Shengli Oilfield and Liaohe Oilfield are well developed. Since the 1960 s,these fields have been working on various sand control methods. Both mechanical sand control and chemical sand control can control the production of formation sand within a certain period of time,but at the cost of part of the production capacity of the gas well. After some processes are implemented,the output is reduced by 70%-80%,which is not conducive to the rapid development of oil and gas fields.
