| 摘 要： | 针对静态堵漏试验仪不能反映井下真实情况的问题 ,研制了JLX— 2动态堵漏试验仪。这种试验仪能较好地模拟井眼条件、地层的裂缝性和渗透性漏失情况 ,其循环流速为 1 31m/s和2 6m/s;动压为 1 2MPa ,静压为 5 0MPa。采用 5%膨润土 +2 %CSW— 1 +0 1 8%SP—Ⅱ +2 %SMP—Ⅰ +0 2 %WFT— 666+5%JOD— 1堵漏钻井液进行了堵漏试验和平行试验。结果表明 ,仪器具有很好的平行性 ,且评选出JQD系列堵漏剂及其堵漏液配方 ,其堵漏时间为 1 4s,漏失量为50ml,在塔里木油田 4口井的试验中均取得成功 ,井漏控制成功率达到 1 0 0 %。

| Abstract: | Static loss plugging tester fails to reveal the actual conditions in a hole. Model JLX—2 dynamic loss plugging tester is thereby developed, which can simulate the borehole conditions and loss of well effectively. Its circulation speed is 1 31m/s and 2 6m/s;dynamic pressure is 1 2MPa,static pressure is 5 0MPa. Dynamic loss plugging trials and lost circulation additives evaluation were made by the tester. And the tester has been used successfully to control the loss of 4 wells in Tarim Oilfield. |
