火烧山油田注水开发以来,由于受地层裂缝的影响,注入水沿裂缝方向舌进,油井含水迅速上升,产油量下降,造成油田暴性水淹,严重影响了油田的稳产。针对这种情况,1989年以来,我们开展了砂岩裂缝油藏油井堵水技术的研究与实验,进行了107井次的堵水工业性试验,对封堵油层裂缝水窜,起到了积极重要的作用。因此,科学地封堵油层裂缝水窜,已成为火烧山油田控水稳油的重要措施。
Since the exploitation of Huoshan oilfield, due to the influence of formation fractures, the water injected into the fracture along the direction of the crack, the water content of the oil well rose rapidly, and the oil production decreased, causing violent flooding in the oilfield and seriously affecting the stable production of the oilfield. In response to this situation, since 1989, we have carried out research and experiments on oil well plugging technology in sandstone fractured reservoirs, carried out 107 well plugging water industrial tests, and played a positive and important role in the water channeling of fractured oil reservoirs effect. Therefore, it is an important measure to stabilize water and stabilize oil in Huoshan oilfield by scientifically blocking water channeling in fractured reservoirs.
