Comprehensive Evaluation Of Low Permeability Reservoir Hydraulic Fracturing Technology And Economic Effects

Development of low-permeability oil and gas reservoirs has become the theme of the growth of the oil and gas reserves, hydraulic fracturing technology as an important means to improve the effect of the low-permeability reservoir harvest, from the economic point of view, the higher the cost. With the upgrading of the level of the operation and management of oil and gas fields, the pressure effect evaluation of gaining the attention of the managers of the oil and gas fields.Evaluation Research of hydraulic fracturing system to summarize and generalize, and analyzes the evaluation of hydraulic fracturing effect, pointed out that the present, our country from the perspective of business management for low permeability gas reservoir fracturing technology and comprehensive evaluation of the economic effects of research is still not perfect. On this basis, the use of hydraulic fracturing to optimize the design, technical and economic, and before and after contrast theory, possession of hydraulic fracturing effect of low permeability gas evaluation and the evaluation criteria, the evaluation and the evaluation criteria not only be able to test the fracturing Relevance of design and the practical effect, but also to enhance the understanding of the extent of oil and gas reservoirs, and can be used to guide subsequent fracturing; followed by the use of the Delphi method to filter the important factors to establish the technical and economic effects of hydraulic fracturing of low permeability gas reservoir integrated evaluation index system; final comprehensive use of the analytic hierarchy process and fuzzy comprehensive evaluation method to form in line with the characteristics of low permeability gas reservoirs, hydraulic fracture stimulation mechanism as well as oil and gas enterprises operation and management mode "comprehensive evaluation of the technical and economic effects of hydraulic fracturing of low permeability gas reservoirs method and verified by an example of the scientific method and operability. The use of this method is not only an important means to improve gas production plant management level but also an important basis of the quality of service assessment technology services company, to provide basis for decision making and theoretical support for the operation and management of the oil and gas field development process.
