| 中文摘要: |
| 钻井冲洗液是影响水井出水量的主要因素之一。通过室内模拟试验，发现了不同钻井冲洗液类型和不同洗井方法对含水层渗透性的影响规律，找到了既有较好护壁性又对含水层有较小封堵作用且封堵后易于冲洗的冲洗液，并对聚合物在含水层中的作用机理进行了初步探讨。同时介绍了两个应用实例。 |
| 英文摘要: |
| Drilling fluids is one of the main factors influencing the yield of water well. Through laboratory simulated tests the regularity of aquifers influenced by different kinds of drilling fluids and well-washing methods is found,a kind of drilling fluid is obtained that not only can protect hole-side very well and have less sealing action on aquifers but also is easy to be washed out from aquifers after sealing action , and the mechanism of polymer in aquifers is initially discussed. Furthermore, the paper introduces two samples of successful application of the resreach. |
