摘要(英):
The invention provides temperature control mud cake cleaning liquid, which is included by the following raw materials, by weight percent, 80%-90% of organic ester mixture, 0.074%-0.1% of preservative, 0.00014%-0.0002% of hydrochloric acid, 5%-8% of calcium salt and the rest is water. The temperature control mud cake cleaning liquid can protect the primary physical property of reservoir stratum well with small amount which is easy to conduct, and can also reduce later development costs to obtain decent economic returns and social benefits, worthwhile for promotion; meanwhile can be transported conveniently, with simple preparing method and required equipment requirements.
