| 中文摘要:深层裂缝性气藏具有异常高压、高产等特点，钻井完井过程中易出现又喷又漏等复杂事故，因此需做好“防漏为主、堵漏为辅”的防漏堵漏措施。通过全尺寸堵漏装置进行了高压静态、动态模拟堵漏实验，优选配方组合，并系统评价了防漏、堵漏配方的封堵能力、承压能力以及酸溶性，评价研究出的防漏堵漏配方，具有酸溶率高、堵塞强度高、返排效果好等特点，为防漏、堵漏方案现场实施提供依据。 |

| Abstract:Deep fractured gas reservoir has the characteristics of abnormal high pressure and high production, and in the well drilling and completion process, blowout and leaky accidents often occur, so leakage proof and blocking are necessary. Experiments were made with full-scale plugging devices in statistic and dynamic high-pressure simulated plugging and combination of optimized formulas; and systematic review was made on plugging capacity, resistance to pressure and acid solubility. The determined formula has the characteristics of high-rate of acid solution, high-strength of plugging and good effect of flow-back, which provides basis for on-site leakage proofing. |
