问答题

【简答题】翻译：The primary limitations for gas lift operations are the lack of formation gas of an outside source of gas, wide well spacing, and available space for compressors on off-shore plat forms. Generally, gas lift is not applicable to single-well installations and widely spaced wells that are not suited for a centrally located power system.

答案：气举操作的主要限制是，缺少地层气体及外部气源的井，在浅海平台上需要为压缩机提供有效的空间。一般来说，气举不适用于单井装置...

【简答题】翻译：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：气举特别适用于那些有高压气体的井，将气体注入井中可能需要装配气体压缩机，或者有高压气井在附近。由于气体压缩费用远远超过井...

【简答题】翻译：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：为某一特殊目的，在压裂液中常常加入其它添加济。假如压裂液可能引起井中管柱的腐蚀，则需要加入防腐济。其它添加济起到让部分压...
