摘要
在钻探过程中经常遇到复杂的地层,如裂隙发育、破碎、断裂、软硬不均、结构松软、膨胀、剥落等,使岩心采取率低、破岩效率差、钻进成本高,在钻进过程中又容易出现漏失、缩进、坍塌、掉块等问题,使得施工难度加大。本文将详细分析各种常见复杂地形的形成原因,并提出几点在复杂地层中进行钻探工作的技术建议。
The complex strata are often encountered in the process of drilling, such as cracks, broken, soft, soft, uneven structure expansion, spalling, the low core recovery, rock breaking efficiency, the high cost of drilling in the drilling process, and prone to leakage, indentation, collapsing and breaking etc. the Problem, make the construction more difficult. In this paper, the reasons for the formation of various complex terrain are analyzed in detail, and some technical suggestions are put forward.
