    摘要:

    聚合物微球是近年来发展起来深部调剖封堵材料,微球良好的弹性性能能够满足调剖剂注得进、堵得住、能运移的要求。室内实验和矿场试验结果表明,聚合物微球能有效封堵高渗条带,提高产油能力。本文从聚合物微球调剖封堵机理出发,抽象化建立聚合物微球调剖封堵流线模型。基于所建立的流线模型,模拟分析聚合物微球注入地层以后流线场的变化,流线的变化对注水井注入压力与采油井生产动态的影响,从流线场角度阐述聚合物微球调剖封堵机理。同时,聚合物微球矿场试验结果表明,注入聚合物微球能很好的抬升注入压力,提高井组产油能力。

    Abstract:

    Polymer microsphere is a deep profile control agent which has been developed in recent years. Microsphere’s excellently elastic property makes it possible to be injected, or to penetrate deep into formation, and plug high permeable layers. Many laboratory investigations have been carried out on polymer microspheres by researchers, and field tests also have been done in some oilfields. The laboratory and field test results show that polymer microspheres can plug pore throats effectively, decrease permeability of high permeable channels, thus force injected water to change its direction and enhance water-flood sweep efficiency. In this paper, based on the mechanisms of profile modifying and plugging of polymer microsphere, Streamline models have been built abstractly to simulate the profile controlling progress of polymer microspheres, observe the transformation of streamline field, and analyze its impact on the pressure of water injection wells and performance of oil wells. In the end, the mechanisms of profile modifying and plugging of polymer microspheres have been interpreted based on the streamline field. At the same time, polymer microspheres pilot test results show that the injective polymer microspheres can be a very good uplift injection pressure, improve its oil production ability.
