摘要
由于地层倾角、软硬交替地层、不同施工工艺等因素影响,钻孔钻进中会出现偏移,而且偏斜方向和偏斜规律在一定区域内,在相似施工条件下具有一定的规律可循。对这些规律进行分析研究,随着大量定向钻孔的实施,利用这种钻孔偏斜规律可以有效降低定向难度,提高施工效率,起到降本增效的目的。
Based on stratigraphic dip,soft hard spacing,different construction technology and other factors,with borehole deflection in drilling,deviation and deflection possess certain rules under similar construction and same area.Based on large quantity of directional drilling,the law of borehole deflection was studied,which enables to reduce the construction difficulty and improve working efficiency,with cost decreasing and benefit increasing.
