摘要
从地质构造应力、井位选择、岩性特征及工程施工四个方面对伦坡拉盆地已钻７口探井的井眼失稳问题进行了分析，认为井眼失稳的主要原因是裂隙面处的泥岩膨胀和地层裂缝发育。
The challenges of φ101.6mm liner cementing under sidetracking through φ139.7mm casing window is studied and the corresponding technical measure is put forward.The slag MTC cementing technique and some casing accessory,such as rigidity stabilizer and sludge scraper,are first successfully used in φ118mm slimholes.Consequently the casing is fully centered and cementing quality is improved.At the same time,a new way to cement in slimhole sidetracking through casing window is developed.
