随着水平井技术的飞跃发展,其酸化解堵、恢复并提高油气产能的问题日趋紧迫。通过对JS-1暂堵剂的粒度分布、分散稳定性、油溶性以及与酸液配伍性进行试验研究,结果表明,JS-1暂堵剂适用于中低渗透率的储层,有较好的分散稳定性和酸液配伍性,可满足现场施工要求。同时通过特制的试验装置对自转向酸性能进行了试验评价,结果发现,不论是暂堵转向分流解堵工艺还是自转向酸转向分流工艺都有转向作用,达到了均匀布酸的目的,对提高水平井的开发效果意义重大。
With the rapid development of horizontal well technology, the problems of acidification and plugging, recovery and increase of oil and gas production capacity are becoming more and more urgent. Through the study on the particle size distribution, dispersion stability, oil solubility and compatibility with acid of JS-1 temporary plugging agent, the results show that the JS-1 temporary plugging agent is suitable for medium and low permeability reservoirs, which is better Dispersion stability and acid compatibility, to meet the requirements of on-site construction. At the same time through a special test device to test the performance of self-steering acid and found that, whether it is temporary block diverting diverting plugging process or diverting from the steering to divert the redirection of the role, to achieve a uniform cloth acid, to improve The development of horizontal wells is of great significance.
