Description

technical field

[0001] The invention relates to a microbial composite bacterial agent for treating oil-based drilling cuttings, its preparation method and its application, and specifically relates to microorganisms constructed by using the interaction relations such as symbiosis, intergrowth and synergy among strains according to the principles of microbial ecology The compound microbial agent, its preparation method and its application belong to the field of microbiology. Background technique

[0002] With the development of oil and gas exploration and development in China, more and more multilateral wells, horizontal wells and complex geological wells are drilled, and the problem of wellbore stability is becoming more and more prominent. As a result, the amount of waste oil-based pollutants produced has been increasing. Among them, oil-based drilling cuttings contain a large amount of pollutants, such as heavy metals and organic matter, and have been listed as national ha...
