Abstract

Most fracture patterns near the well region are more fickle in tight gas field than that in literature. In this paper, a modified discrete fractured well model is presented to account for dynamic characteristics of a vertical well with multiple asymmetrical fractures (MAF). Fracture closure effect is also coupled in the revised numerical model, leading to a more rapidly loss of gas production. The productivity of a vertical well with MAF is investigated by comparing to a fractured well with one single equivalent fracture (EF). Furthermore, the effect of fracture conductivity on cumulative production is discussed. Results show that EF representation can cause up to 45.4 percent less production than MAF. Fracture conductivity is proved to be closely related to cumulative production.
