河北金特爾鉆頭有限公司為您提供江漢鉆頭川石鉆頭牙輪掌,。牙輪鉆頭結(jié)構(gòu)特點(diǎn):
1、采用浮動(dòng)軸承結(jié)構(gòu),,浮動(dòng)元件由高強(qiáng)度,、高彈性、高耐溫性,、高耐磨性特點(diǎn)的新材料制成,,表面經(jīng)固體潤(rùn)滑劑處理。在降低軸承副相對(duì)線速度的同時(shí),,減少摩擦面溫升,,能有效提高高鉆壓或高轉(zhuǎn)速鉆井工藝條件下的軸承壽命和軸承---性。
9,、牙掌側(cè)面鑲裝有一定出露高度的切削齒,牙輪鑲修邊齒即t特殊結(jié)構(gòu),,使鉆頭的側(cè)切能力---加強(qiáng),,并---的井身。
10,、鋼球鎖緊牙輪,,適應(yīng)高轉(zhuǎn)速。
牙輪鉆頭型號(hào)與地層的選擇介紹:
114. 115.116.117 低抗壓強(qiáng)度高可鉆性的及軟地層,,如粘土.泥巖.疏松砂巖.
the 114-117 bits are used to drill low-compressive strength,soft formations. long projection tooth lengths are used on high offset cones to provide the greatest penetration rates possible. wear-resistant hard facing is used to control tooth wear.on the softest bi types this hard facing completely covers the bit teeth 0.35---0.8 150---80
124.125.126.127 低抗壓強(qiáng)度高可鉆性的及軟地層,,如泥巖.石膏.鹽巖.軟頁(yè)巖.軟石灰?guī)r
soft formation with low compressive strength&high drillability. such as sandstone, anhydrite, salt, shale, limestone. 0.3---0.9 180---80
134.135.136.137 低抗壓強(qiáng)度高可鉆性的及軟至中軟地層,如中軟頁(yè)巖.硬石膏.中軟石灰?guī)r.中軟砂巖和有硬夾層的軟地層
soft to medium formations with low compressive strength, such as shale, anhydrite, sand&so on for soft formation 0.33--1.0 130----60
216.217 低抗壓強(qiáng)度的軟到中等地層,,如中軟頁(yè)巖.中軟石灰?guī)r.中軟砂巖.和有硬夾層的軟地層
soft to medium formations with low compressive strength, such as shale, anhydrite, sand&so on for soft formation 0.4---1.0 100---60
