双通道平行井在采卤对接井中的首次应用

First Application of Double Channel Parallel Wells in Connected Brine Wells

摘要:

结合土耳其贝帕扎里天然碱矿三期工程增补合同中H022UA井实例，介绍双通道平行井的轨迹设计、应用目的以及在首次应用中遇到的问题和解决措施。虽然经历了矿层抬升、靶点溶腔过小、下钻困难、钻遇未知溶腔等一系列困难，经过采取有效的技术措施，H022UA井最终对接成功，完井循环。为今后施工类似工程提供了可借鉴的经验。

Abstract:

The paper introduced the double channel parallel wells about the trajectory design, application purpose, problems encountered in the first application and the countermeasures with the case of H022UA well in Beypazari natural alkali mine of Turkey. In spite of the difficulties of ore bed uplift, small target cavity, difficult drilling and drilling in unknown cavity, H022UA was connected successfully at last by the effective technical measures.
