摘　　要：地热井等一些特殊井通常采用上大下小的双径套管串结构 ,常规的固井方法无法满足该类井的固井要求。介绍了解决双径套管一次性固井的三种方法 ,并分析了三种方法的特点 ,认为采用双径胶塞是解决双径套管固井最安全、经济、可靠的方法。Some exceptional wells such as geothermal well etc.ofter adopt double-diameter casing structure.Regular cementing method can't meet the requiremetns of the well's cementing.The paper presents three methods for solving one-trip cementing problem on double-diameter casing and analyses the features of the three methods.The analysis results show that using double-diameter rubber plug is the safest,economic and reliable method for solving double-diameter casing cementing.
