Hydraulic fracturing benifits

hydraulic fracturing benefits is a widely used technology transformation permeability reservoir . Since the eighties of last century , with the development of the oil industry , the need to increase the complexity of the transformation of the reservoir , it is recognized that a single plane of crack theory can not satisfactorily explain some of the construction parameters of the construction of the theory ; variety of detection methods prove underground cracks on the transverse or longitudinal extension of multiple simultaneously , which is caused by the reasons for the early sand plug and add sand construction failures ; currently on theoretical models and more cracks less . Therefore, an urgent need to study the formation mechanism of multiple fractures , multiple fracturing fluid , etc. while extending the model to study and understand the pros and cons exist multiple fractures , multiple fractures extending construction abnormal pressure , cracks and more cracks in the case of extended form, early sand blocking mechanism etc. , and thus provide for the elimination of multiple fractures theoretical support to guide people to the smooth transformation of low permeability , complex reservoirs . On the other hand , it will enhance people's understanding of the mechanism of fracturing , and promote the development of basic theory. Theory is the theory of multiple natural gas fracturing forefront of hydraulic fracturing theory, research more difficult , facing a lot of problems
