The invention provides a gathering and transportation pipe network optimization method and device, and the method comprises the steps: dividing a target region into a plurality of sub-regions with grid nodes according to topographic parameters; wherein the grid nodes are used for topology of a feature set transmission pipe network; generating constraint conditions of a preset gathering and transportation pipe network optimization model according to the terrain parameters, the pipe network technical parameters and the drilling data information; wherein the well drilling data information comprises well position coordinates of an existing well of the target area, existing and expected production data of the existing well, well position coordinates of an expected well and expected production data; generating the gathering and transportation pipe network optimization model according to the constraint condition and the cost objective function; and according to the gathering and transportation pipe network optimization model, a gathering and transportation pipe network optimization result is generated, the gathering and transportation pipe network optimization method planned comprehensively from the perspective of time can be provided, the method can guide engineering construction of the oil and gas field, and cost reduction and benefit increase of the oil and gas field are facilitated.
Description
technical field [0001] The invention relates to the field of oil and gas production, in particular to oil and gas storage and transportation technology in oil and gas fields, and in particular to a design method and device for a gathering and transportation pipeline network. Background technique [0002] During the construction process of oil and gas fields, with the continuous increase of the development degree, the gathering and transportation pipeline network becomes large and complex, resulting in the rising proportion of the gathering and transportation pipeline network construction cost in the investment of the entire oil and gas field. In terms of production, the gathering and transportation pipeline network composed of well sites, pipelines, pressure equipment and central processing facilities plays a key role in the production of natural gas fields. Therefore, the optimization of the gathering and transportation pipeline network is crucial for reducing development co...
