| 摘 要： | HRD弱凝胶钻开液是一种新型无粘土相水平井钻开液，它所形成的弱凝胶具有独特的流变性，表观粘度低、动塑比高、低剪粘度高、静切力恢复迅速、无时间依赖性，具有很好的动态携砂和静态悬砂能力，能有效地克服水平井或大斜度井段携砂难、易形成岩屑床等问题。同时该体系在低剪切状态下具有高粘弹特性，可减少钻开液中固相和液相对储层的损害，有利于储层保护。在冀东油田水平井应用时，井壁稳定、可有效抑制岩屑床的形成，井眼畅通保证了钻井和完井作业的顺利进行。 |
| 关 键 词： | 弱凝胶 水平井 储层保护 低剪粘度 钻开液 |

| Abstract: | HRD weak gel drilling fluid is a novel horizontal-well drilling fluid without clay.Independent on time,the weak gel is characterized by a special rheological behavior,a low apparent viscosity,a high dynamic plastic ratio,a high low-shear viscosity,a quick recovery of static shear force,a better ability of both dynamically carrying sand and statically suspending sand.In addition,the gel can effectively solve some problems,for example,difficultly carrying sand in horizontal well and large-deviated well sectio... |
| Keywords: | weak gel horizontal well reservoir protection low shear viscosity drilling fluid |
