Horizontal wells and hydraulic fracturing are the most effective technologies in the exploitation and development of tight gas reservoirs. Hydraulic fracturing with large volumes of proppant and water will not only create high conductivity primary fractures but also stimulate adjacent natural fractures. Fracture network forming around every hydraulic fracture yields a stimulated reservoir volume (SRV). A conceptual model which was based on a tight gas sand reservoir in Northeast China was established to analyze the effect of related parameters on the production of multi-fractured horizontal wells. In order to analyze the impacts of related parameters on production, a series of simulation scenarios and corresponding production performance were designed. Simulation results showed that the number of primary fractures, half length, SRV half-width and drop-down have great effects on the post-fracturing production. Formation anisotropies also control the production performance while the conductivity of the primary fractures and SRV permeability do not have much impact on production performance. Fracture number mainly affects the early time production performance. The increase of SRV width cannot broaden the drainage area of the multi-fractured horizontal wells, but it can really improve the recovery in its own drainage region. Permeability anisotropies have much effect on production rate, especially the late time production rate.

MNK Publication was founded in 2012 to upholder revolutionary ideas that would advance the research and practice of business and management. Today, we comply with to advance fresh thinking in latest scientific fields where we think we can make a real difference and growth now also including medical and social care, education,management and engineering.
We offers several opportunities for partnership and tie-up with individual, corporate and organizational level. We are working on the open access platform. Editors, authors, readers, librarians and conference organizer can work together. We are giving open opportunities to all. Our team is always willing to work and collaborate to promote open access publication.
Our Journals provide one of the strongest International open access platform for research communities. Our conference proceeding services provide conference organizers a privileged platform for publishing extended conference papers as journal publications. It is deliberated to disseminate scientific research and to establish long term International collaborations and partnerships with academic communities and conference organizers.
