| 摘 要： | H001LA井为土耳其贝帕扎里采集卤钻井三期工程中的定向水平对接井,在三期设计里处于由不同目标矿层和多种井组型式组成的复杂井组中。在钻井施工中,遇到了目标矿层缺失、地层起伏大、涌水严重、钻遇巨大溶腔和地层坍塌等严重问题。经过问题分析,通过对3个可行性方案的比较,采用了成本低、工期短和更加安全的施工方案,最终顺利完井。

| Abstract: | As one of the horizontal wells in the project of Turkish Beypazari trona solution mining Phase Ⅲ,H001LA is complicated in well layout comprising different main trona seams and varieties of well units styles in the design.Many difficulties encountered during the construction process such as loss of main trona seam,serious undulation of the formations,brine outflow,drilling to large cavity and formation collapsing.By the comparison analysis on the 3 feasible construction schemes,one was adopted with low cost,short construction period,high safety coefficient and successful well completion. |
