Abstract:

Baimiao Gas Field belongs to a tight sandstone condensate gas reservoir which is characterized with complicated
structure,deep burial,poor reservoir property,high content of condensate oil,showing small differential pressure,high formation
pressure. Gas well fracturing stage generally has a higher capacity. But with the condensate blockage flow channel in
the near wellbore area precipitation,the production fast declines and the stable production period shortens. The vertical well
technology has been used in the development of the gas field,which is of low recovery degree and poor development effect.
The development of horizontal well can increase the production rate and the recovery of gas reservoir. According to the geological
characteristics of the gas reservoir,and through in-depth study of the geological characteristics,we recognize the local
structure and the distribution rule of reservoir. Horizontal well test was carried out to study the development of this kind of gas
reservoir. We optimized 2 horizontal wells and obtained initial effect which has a certain guiding significance for the rational
development of tight sandstone gas condensate gas reservoir.

Key words: horizontal well, optimization design, tight sandstone, condensate gas reservoir, Baimiao Gas Field
