Network Fracturing and Its Application to Continental Shale Gas in Ordos Basin

Abstract

Abstract: Well stimulation is necessary for the production of continental Yanchang shale gas in Ordos Basin in view of its low content of brittle minerals and high content of clay minerals. This paper discusses the feasibility of network fracturing based on the analyses of the technique, shale gas reservoirs, stress field and natural fractures. Taking Chang 7 Member of Yanchang Formation in Well J1 as an example, mini frac and net pressure matching are used for fracturing design and operation, and numerical simulation is used for parameter optimization. Microseismic monitoring shows that all perforation intervals have been effectively connected by the fracture network.
