    • Abstract
  • The Xu 5 gas reservoir in the Xinchang Gas Field is a tight gas reservoir composed of interbeds of sandstones and mudstones. It is characterized by deep burial depth, strong heterogeneity, local fracture development, distinct water bearing properties, multi-layer superposition, low natural productivity and positive economic development is difficult. In order to solve these problems, an integrated technology which combines a low-cost high-performance fracturing fluid system, high flow rate and a two-way injection string with network fracturing optimization design was developed, taken the economic fracturing as the core and volumetric fracturing of shale-gas-reservoir as new concept. Field application in 21 wells showed that the integrated technology was of deep importance and could unlock steps that would result in efficient productivity. The technical scheme was considered to be reliable, and it can provide a strong technical support for, in the future, developing the gas reservoirs efficiently.
