| 摘 要： | 介绍钻孔结构设计的依据和原则,提出李三台子深孔钻孔结构设计口径与套管级配关系和考虑的因素。钻孔设计结构和实际结构对比分析,换径及下套管所要注意的问题。建议深孔钻进必须下套管,加大开孔直径,留足下套管隔离复杂地层的空间,下套管做好细节工作,为处理井内事故和起拔套管时打好基础。

| Abstract: | Evidence and principle for structural design of drill hole 2500 m-deep for general prospecting in Lisantaizi iron mine are presented and match relation of diameter of the designed drill hole to casing tube and factors considered are put forward in the paper.Based on comparison and analysis of the designed structure and the real structure of the drill hole much attention should be paid to change of diameter and putting down casing tube.Proposal about putting down casing tube during drilling is made to enlarge collar diameter and leave enough space for putting down casing tube and separate drilling from complicated strata and details for putting down casing tube must be done for accident treatment in the hole laying good foundation for drawing out of the casing tube. |
