查询词典 gas can

To control deviation, the actual WOB is usually adopted in the lower range, which results in ROP increasing is unconspicuous and predominance of gas drilling can't be showed.

在实际气体钻井过程中，为了控制井斜，通常都将钻压控制在较低的范围内，这就导致气体钻井提高机械钻速不明显，不能充分发挥气体钻井的优势。

Mainly we can start from three aspects, power saving, gas saving and recycle so as to stop acceleration of global worming.

我们可以从节电、节气和回收三个方面做起，以阻止全球变暖的加速发展。

According to the property of mud of gas of plum steel blast furnace, undertook to its zincic experiment studies receiving iron to fall, no matter use magnetic separation,the result makes clear or classification the law all can reclaim from which content of major iron ore and purify is major zinc, stock of will tall zinc, low zinc undertakes effective depart, iron concentrate yield and grade all achieve 52% above, iron metal reclaims rate 70%, take off zinc to lead 50% above.

梗概： 介绍了梅钢高炉瓦斯泥的性质、试验情况及结果，国内外处理使用含锌高炉瓦斯泥的方法。根据梅钢高炉瓦斯泥的性质，对其进行了收铁降锌的试验探究，结果表明无论用磁选还是分级法均能从中回收大部分铁矿物并去除大部分锌，将高锌、低锌物料进行有效分离，铁精矿产率和品位均达到52%以上，铁金属回收率70%，脱锌率50%以上。

A larger area of reserves can be managed and significant increase in the recovery ratio will be achieved by multibranch horizontal gas wells, which in fact have been used more and more widely in China.

多分支水平井能控制更大的储量面积，大幅度地提高油气藏采收率。

The cost of MRC technology is lower than that of single horizontal well. It can drill two or multibranch hole from one major bole and encounter the pay zones in different positions, which improves the drilling-in capability and effective area and increases the oil and gas production of individual well.

MRC技术除具有水平井的常规优势外，其成本比单个水平井低，它是在一个主井眼中钻出两个或多个分支井眼，从而钻遇多个不同空间位置的产层，增大储层钻穿几率和有效面积，进而提高单井油气产量。
