工程地质钻孔口径及钻具规格

工程地质钻孔口径及钻具规格

工程地质钻孔口径及钻具规格如下：
钻头类型：
钻杆钻头：直径为5-12毫米，一般用于岩石较硬的地质钻探，例如花岗岩、玄武岩等。

扣肋钻头：直径为42-45毫米，一般用于较软的地层钻探单元。

三角钻头：直径为28-45毫米，适用于基岩层近地表部分地质钻探。

切锥钻头：直径为46-65毫米，适用于岩石中硬度较高的区域地质钻探。

三刃钻头：直径为28-65毫米，适用于各种不同类型的地质钻探。

钻孔规格：
钻孔口径应根据钻探目的和钻进工艺确定。

采取原状土样的钻孔，口径不得小于91mm；仅需鉴别地层的钻孔，口径不宜小于36mm；在湿陷性黄土中，钻孔口径不宜小于150mm。

深度超过100mm的钻孔以及有特殊要求的钻孔包括定向钻进、跨孔法测量波速，应测斜、防斜，保持钻孔的垂直度或预计的倾斜度与倾斜方向。

对垂直孔，每50m测量一次垂直度，每深100m允许偏差为±2°。

对斜孔，每25m测量一次倾斜角和方位角，允许偏差应根据勘探设计要求确定。

钻孔斜度及方位偏差超过规定时，应及时采取纠斜措施。

钻进与护壁：
钻进方法应符合下列要求：对要求鉴别地层和取样的钻孔，均应用回转方式钻进，取得岩土样品。

遇到卵石、漂石、碎石、块石等类地层
不适用于回转钻进时，可改用振动回转方式钻进。

钻井工程钻头尺寸标准

钻井工程钻头尺寸标准
M3钻头：全长65mm、柄径6.4mm、刃长35mm、小径3.4mm、大径6.4mm。

M4钻头：全长75mm、柄径8.4mm、刃长42mm、小径4.5mm、大径8.4mm。

M5钻头：全长85mm、柄径10.4mm、刃长50mm、小径5.5mm、大径10.4mm。

M6钻头：全长90mm、柄径12.0mm、刃长53mm、小径6.6mm、大径12.5mm。

复合片钻头的外径一般来说会比电镀钻大2-3mm,这是因为复合片钻头主要应用于破碎地层和砂石层,对保径的要求更高一些,所以有必要对外径加大处理。

钻头是有很多规格标准的,像一些水管通过的钻孔相对来说要大些,而电线所需的钻孔要小得多,因此钻头直径也是有差别的。

钻头直径规格大致有1mm、2mm、3mm、4mm、5mm、6mm、7mm、8mm、9mm。

3、本体尺寸7"及以下规格钻具严禁使用无任何指示仪表（扭矩、压力）的液压动力钳上卸扣，本体尺寸7"以上钻具应使用带扭矩指示的猫头紧扣；
4、严禁使用未经检验校检的液压动力钳紧扣；
3、液压动力钳扭矩KN.m与压力Mpa单位对照关系：
（1）ZQ100型液压钻杆动力钳KN.m与Mpa对照关系约为6:1；
（2）XQ140 /12YA型油管液压动力钳KN.m与Mpa对照关系为1:1。

三、加重钻杆三、加重钻杆三、钻杆1、API钻杆加厚尺寸图（X、G、S）四、转换接头：1、转换接头的种类转换接头根据外形与使用分为以下三种型式A型（同径式）：一只转换接头只有一种外径尺寸，代号为JTA。

B型（异径式）：一只转换接头只有两种外径尺寸，代号为JTB。

C型（左旋式）：转换接头的连接螺纹为左旋形式，代号为JTC转换接头的种类（SY5200—93、SY/T6152—1995）注：（1）、转换接头的连接螺纹弯曲强度比应控制在3.20：20—1.90：1之间。

（2）、转换接头的钻具当其直径差大于15mm时可采用B型转换接头（水龙头转换接头和打捞转换接头除外）。
