1·This fracturing system—which eliminates rig up and rig down between stages— reduces overall pumping time while maximizing reservoir contact to increase drainage.

整个压裂过程避免了起下钻操作，减少泵注时间的同时，实现了油藏泄油面积的最大化。

2·A rig pounds an inlet out of the coast, sending rubble rattling down a pipe to the sea.

一个操控装置敲击着海滩上突出的入海口，把碎石咔哒咔哒送进通向海里的管子。

3·A big rig had tumbled down an embankment, and flames were crawling across its cab.

一辆双拖斗卡车斜停在路堤上，火焰在它的驾驶室蔓延。

4·Recent evidence supports this conclusion: while the USA rig count is down 50% in one year, production has fallen much less.

5·Canadian rig Count is unchanged from last week at 76, with oil RIGS down 1 to 35, gas RIGS up 1 to 40, and miscellaneous RIGS unchanged at 1.

上周加拿大钻机总数仍为76台，油井钻机减少了1台，数量为35台，气井钻机增加了1台，数量为40台，其它钻机的数量保持1台不变。

6·Compared to this time last year, the overall us rig count is down by 202 RIGS, with oil RIGS down by 122, gas RIGS down by 82, and miscellaneous RIGS up by two.

与去年同期相比，全美钻机数量减少了202台，其中石油钻台减少了122台，天然气钻台减少了82台，混合型钻台增加了2台。

7·Masts are usually rectangular or trapezoidal in shape and offer a very good stiffness, important to land rigs whose mast is laid down when the rig is moved.

桅架的形状一般呈矩形或者梯形。具有很好的刚度，对于陆地钻机而言非常重要，当钻机移去时，桅架需要放倒。

8·Do not use tractors to replace the rig power system for mast lifting and laying down.

不应使用牵引车代替钻机动力系统进行起放井架作业。

9·Canadian rig count is down 63 RIGS from last year's count of 139, with oil RIGS down 37, gas RIGS down 27, and miscellaneous RIGS up 1.

与去年139台的总数相比，今年加拿大钻机减少了63台，其中油井钻机减少了37台，气井钻机减少了27台，其它钻机增加了1台。

10·This standard specifies the technical requirements special regulations on the inspection lifting and laying down of self-erection mast of land rig.

本标准规定了陆地钻机自升式井架起放作业的检查、起升和下放技术要求及特殊规定。
