Research on Ground Process Flow Optimization of Shale Gas Platform
The shale gas in southern Sichuan has enormous exploration and development potential,and the deep shale gas blocks with abundant resources will become the main areas for shale gas produc-tion during the"14th Five-Year Plan"period.With the continuous and rapid large-scale production of shale gas fields in southern Sichuan,in the practical application of the standardized system of shale gas fields,it gradually reflects some problems:easy damage of wellhead throttle valve,high investment of platform equipment,low efficiency of desander,and easy failure in some locations.In order to solve related problems,through fine control of wellhead pressure,change of measurement method,reduc-tion of equipment design pressure,improvement of desander's performance,optimization of pipe fit-tings selection in critical parts,the standardized ground process of shale gas is continuously optimized and simplified,and the precise pressure control at the wellhead and two-phase flow non-separation sand removal metering process is launched.This process can effectively reduce the system failure rate,improve operation stability,reduce ground construction investment,and improve single well EUR,which provides a new idea for the efficient and low-cost development of shale gas.
