(3) the inclination of the borehole is pendulous in the shallow drilling of the metamorphic rocks in the rock, gneiss and other layers.
(4) when the borehole is deep, the bending rule of t16岁单身女生微信二维码 - 微信小妹免费聊天 - 单身女生微信二维码 - 百度he borehole is divided into two sections, and the beginning of the dip Angle is floating, and then gradually the straight hole section goes down to the dip Angle.
(5) the causes of borehole bending are also caused by the combination of geological factors and technological factors.
2. Prevention of borehole bending.
In order to prevent the bending of borehole, it can be solved by using the necessary anticlinal measures in advance in the opposite direction in advance, according to the law of borehole bending in the area.
3. The conventional inclinometer of the ground bit can be used for the drilling of large dip Angle, and special measuring instrument must be used in the horizontal hole. For example, the domestic XJS -- 35 special horizontal side inclinometer (for non-magnetic ore bodies), the main technical parameters are as follows:
Instrument external diameter x measurement total length: 30mmx1100mm;
Drift diameter: 0 ° to 60 ° (Yang, prone), dividing value 2 °, error of plus or minus 1 °;
Azimuth measurement range: 0 ° to 360 °, dividing value 2 °, the error of plus or minus 2 °
