麻烦果友帮忙翻译一下下列钻井词汇或句子 [复制链接]

1. depleted reservoirs
2.Casing drilling has been employed in many countries as an effective method of reducing the overall drilling costs by reducing drilling time and drillstring problems encountered during conventional drilling process. In addition to the productive drilling time lost to tripping, unscheduled events during tripping can make the drilling process even more inefficient and even lead to loosing the well. While the potential savings from reducing drill-string tripping and handling times are important, the savings from reducing hole problems may be more significant. There are many situations where problems such as lost circulation, well control incidents, and borehole stability problems are directly attributed to tripping the drill-string and other situations where these problems prevent the drill-string from being tripped. Since the CDS process provides a continuous ability to circulate the well, it is inherently safer than leaving the well static without a means of circulating it while a conventional drill-string is tripped.
Reduced pipe tripping with the CDS should also reduce surge and swab pressure fluctuations.
There are two basic methods of drilling with casing (Fisher et al., 2004):
3. A short wireline retrievable bottom hole assembly (BHA) consisting of at least a bit and expandable underreamer (Fig. 1) are used to drill a hole of adequate size to allow the casing to pass freely.

是你的作业吧？这都需要别人翻译？

1.枯竭油气藏
2.一些国家把套管钻井作为一种可通过减少钻探时间和降低在常规测井过程中遇到的钻柱问题来节约整个钻探经济成本的有效方法。除了起下钻所损耗的生产性钻井时间外，起下钻过程中的意外事件能使钻井效率低下，甚至导致失去整个井。比起通过减少起下钻具组和处理时间来潜在的节省时间的重要性来说，通过减少井眼问题来节省时间可能更有意义，有些情况像泥浆漏失、井控事故以及井眼稳定性问题都会直接归咎于起下钻具组和为防止钻具遇卡问题而带来的其他情况，因为套管钻井系统能够用连续循环钻井液传井具，其自身的安全性能要比常规测井钻井具遇卡时不循环只静态传井具要好得多。
通过套管钻井系统降低起下管柱
套管钻井有两种基本方法
3.短线缆可回收井底钻具组合至少由一个钻头和一个可用于能钻到使套管自由通过的钻井规模的扩充扩孔器。

要熟读版规

回复恩泽油露 ：要不我把英语原文发给你，你看到底是不是作业，本人上班19年还要写作业啊，英语原文那是萨格勒布一个学生写的钻井水平井文章，同事对原文的翻译持不同意见，才拿出来讨论的啊。谁要说这是作业，我愿和打赌，2000元，我把原文发到他的邮箱。如果查实不是作业，他给我付2000，如果这与我说的不符，我付给他2000

由于套管钻井能有效降低钻井总成本和钻井时间，并且能减少常规钻井过程中发生的钻具问题，因此在很多国家得到了应用。常规钻井技术，除了起下钻作业耗费生产性钻井时间外，起下钻过程中发生的意外情况也会降低钻井工作效率，严重时甚至能使井筒报废。套管钻井技术不但能节省起下钻时间，更能有效避免钻井时的井筒问题。钻杆钻井容易产生循环漏失、井控事故等问题，而且起下钻会直接影响到井筒的稳定性，并使起下钻作业受阻。由于套管钻井时井筒始终保持循环状态，而常规钻杆钻井起下钻时，钻井液无法循环，由此套管钻井本身就具有更好的安全性。
Reduced pipe tripping with the CDS should also reduce surge and swab pressure fluctuations.  套管钻井技术也能减少钻井过程中的抽汲压力和波动压力。

短电缆回收井底钻具总成由钻头和可扩张式扩孔钻组成，可钻出足够大的井筒让套管自由通过。

5楼做的更准一些。
