The advantages of air drilling are that it is usually much faster than drilling with liquids and it may eliminate lost circulation problems.
空气钻井的优点是,比采用液体钻井时快得多,并可能会消除循环漏失的问题。In the realism of the name, itself founded on the imaginary, a dire is missing--one is interdicted from admitting this homage.
在命名的现实主义,它本身的基础上想象界,有一种「灾难」正在漏失---我们被禁止不能承认这种致敬。There is a Tibetan saying: "If you are too clever, you could miss the point entirely. "
西藏有句话说:“你太聪明,反而会漏失重点。”At last, we obtained a relation between the leakage and the pressure, and this will provide reference for the practical use.
最后通过试验数据处理,获取了漏失量的关系式,为相关油田应用提供了依据。High killing fluid density can lead to high loss rate of killing fluid and high dosage, thus results in high cost of killing well.
压井液密度过高导致了压井液漏失率高及用量大,由此带来高的压井成本。Applying the jet pump will reduce the pressure from the circulating fluid, avoiding the heavy leakage of working fluid into the formation.
通过喷射泵的应用减轻了循环液流对井底压力,避免了冲砂液在地层中的大量漏失。remember that even if you miss a bit or fet a couple of lines, nobody know except you.
(记住即或你漏失一点或忘失几行,除开你本身,旁人是不会发明的)。Bag of compound shot-off of loss, make simple, basically use at interstitial sex leakage to break.
复合堵漏袋,制做简单,主要用于裂缝性漏失。Drilling with manageable losses has been employed as a tool to reach target depths set for sections of the well.
可控漏失钻井被当成一种工具来使用,以到达油井断面设定的目标深度。
