Abstract

The invention provides an optimization method for a coal-bed gas field acquisition system. The method includes the steps of establishing the relational objective function of the total gas production capacity of a gas collecting pipe network and the output of each gas well; according to the data of a ground pipe network, establishing the flow model of the ground pipe network; according to the dataof a gas well structure, establishing a cylinder flow model; according to stratigraphic restraint conditions, establishing a capacity constraint model and a bottom hole flow pressure constraint modelrespectively; taking the ground pipe network flow model, the cylinder flow model, the capacity constraint model and the bottom hole flow pressure constraint model as constraint conditions to bring into the relational objective function, and according to the parameters of each gas well, calculating to obtain the output of each gas well.

Description

technical field [0001] The invention relates to the field of natural gas gathering and transportation pipeline network design, in particular to an optimization method for a coalbed gas field collection system. Background technique [0002] At present, coalbed methane has gradually changed from a "gas" that was initially simply discharged to a clean energy that is conducive to sustainable development, and has become an important "unconventional energy". Due to the short development time (in China, it has just gone through about two five-year plans), the gathering and transportation of coalbed methane often borrows the technology of natural gas fields. However, due to the different storage methods, the gathering and transportation of coalbed methane also has certain particularities. The national "Eleventh Five-Year Plan" and "Twelfth Five-Year Plan" major science and technology projects have conducted research on this. The "Eleventh Five-Year Plan" proposed a "multi-point ac...
