【簡答題】翻譯：Gas lift is particularly applicable for lifting wells where high-pressure gas is available.Gas compressors may have been installed for gas injection, or high-pressure gas wells may be nearby. Since the cost of compression far exceeds the cost of down hole gas lift equipment, gas lift always should be considered when an adequate volume of high-pressure gas is available for wells requiring artificial lift. Most wells can be depleted by gas lift,which is particularly true since the implementation of reservoir pressure maintenance programs in most major oil fields.

答案：氣舉特別適用于那些有高壓氣體的井，將氣體注入井中可能需要裝配氣體壓縮機(jī)，或者有高壓氣井在附近。由于氣體壓縮費(fèi)用遠(yuǎn)遠(yuǎn)超過井...

【簡答題】翻譯：Other additives are often added to the fracturing fluids for special proposes. Corrosion inhibitors may be used if the fracturing fluids might cause corrosion in the tubular goods in the well.Other additives are used to make the part of the fracturing fluid which is moving against the pipe walls behave almost like lubricating oil while the remaining fracturing fluid take an almost solid form to carry the maximum amount of proppant.

答案：為某一特殊目的，在壓裂液中常常加入其它添加濟(jì)。假如壓裂液可能引起井中管柱的腐蝕，則需要加入防腐濟(jì)。其它添加濟(jì)起到讓部分壓...

【簡答題】翻譯：The HF-HCI mixture (usually 3-percent HF and 12-percent HCI) then is injected. The HF reacts with calys, sand, drilling mud, or cement filtrate to improve permeability near the well-bore.The HCI will not react and is present to keep the PH low, preventing precipitation of HF reaction products. Sent to keep the PH low, preventing precipitation of HF reaction products.

答案：隨后，HF-HCI混合物(一般3%HF+12%HCL)注入。HF與與黏土、砂、鉆井泥漿或水泥漓液反應(yīng)，以改變近井地帶的滲...
