Abstract

Abstract:

It is an effective way to realize efficient production of shale gas to adopt corresponding production mode in different production stages. The southern area of Pingqiao anticline in Nanchuan Block is a normal pressure shale gas reservoir with relatively low production and wellhead pressure, so the production mode needs to be further optimized. By analyzing the production characteristics of 30 wells in different stages in the southern area of Pingqiao, the reasonable production mode is summarized. The results show that the shale gas well can be divided into five production stages: pressure control, production increase and liquid carrying, intermittent production, pressurized production and low pressure and low production. In the stage of pressure control production, the principle of “keeping pressure + discharging liquid” is adopted to run downhole choke to improve the production cycle. The downhole choke is taken out to prevent the gas well from accumulating liquid in the stage of increasing production and carrying liquid. Measures such as gas lift, foam drainage are adopted in the intermittent production stage. Compressor is used to reduce the influence of pipeline gas transmission pressure in the pressurization stage. Low cost drainage technology such as jet pump is adopted in the stage of low pressure and low production. The mode has achieved good application effect in the south area of Pingqiao, which can provide reference for the development of normal pressure shale gas reservoir in the complex structural area of basin margin.

Key words: shale gas, production characteristics, production stages, mode of production, normal pressure, Nanchuan Block
