Oil and gas reserves in our country are large and widely distributed, and usually fracturing techniques are needed to extract oil and gas. Currently, the more mature hydraulic fracturing technology is difficult to extract coal bed methane. Combined with the research progress of fracturing at home and abroad, this paper summarizes the development of relevant anhydrous fracturing technology, fracturing fluid, fracturing process and other aspects, compares and analyzes the advantages and disadvantages of fracturing technology, and provides some ideas for the development of anhydrous fracturing technology in the future. In order to reduce the cost of anhydrous fracturing, meet the requirements of field application, and accelerate the research progress of anhydrous fracturing, the commonly used fracturing technologies are combined to study new fracturing fluids and carry out composite anhydrous fracturing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
