Gas field gathering and transportation natural gas treatment equipment distribution method and device

Abstract

The invention relates to the field of natural gas field development and production, in particular to a natural gas gathering and transportation technology, and particularly relates to a gas field gathering and transportation natural gas treatment equipment distribution method and device. The method comprises the following steps: preparing basic data required by a model; inputting the basic data into the established gas field gathering and transportation natural gas processing equipment distribution model for solving; analyzing and displaying a result, wherein the model achieve unique numberingof equipment by defining an equipment model set and an equipment number set, and the depreciation coefficient, the equipment processing capacity, the scheduling execution and the market demand are considered in the constraint condition. An MILP model is established to solve the gas field gathering and transportation natural gas processing equipment distribution problem, and a gas field gatheringand transportation natural gas processing equipment distribution optimization scheme under multiple periods can be obtained and comprises the equipment processing flow of each block in each period, the types and the number of purchasing, moving and selling and the specific equipment.

Description

technical field [0001] The invention relates to the field of natural gas field development and production, in particular to natural gas gathering and transportation technology, and in particular to a method and device for distributing gas field gathering and transportation natural gas processing equipment. Background technique [0002] In the process of gas field gathering and transportation, it is necessary to use processing equipment to carry out processes such as deacidification, decarbonization, and dehydration of the wellhead natural gas, so as to convert it into qualified natural gas that meets the national standard temperament requirements, and then transport it to other demand points. In recent years, with the development of serialization, modularization and skid-mounted technology, natural gas processing equipment can often be moved, and has the characteristics of small footprint, convenient demolition, easy flow, and low development risk. It is widely used in oil an...

AI Technical Summary

Problems solved by technology

③ For different blocks, natural gas processing equipment can be disassembled and moved, and moved between different blocks, so there will be scheduling problems

But there are the following problems: ①In a single block, only a single device of a certain specification can be selected, and multiple devices of the same specification cannot be selected. For example, only one device with a processing capacity of 100,000 square meters can be selected, and cannot Choose 2 devices with a processing capacity of 100,000 square meters

In actual production, the same block often contains multiple devices of the same specification, resulting in an unoptimized solution

② It does not consider how much the processing capacity of a specific device should be determined, and the resulting scheme is not conducive to actual operation

③Unable to realize the unique number of a single device, resulting in the inability to realize the precise tracking of the scheduling plan, and the obtained scheduling plan is not specific to the equipment, resulting in the scheduling plan is not uniquely determined during execution

④ In the model, the loss caused by the sale of equipment is considered, but a fixed coefficient is often used, and the difference in the service life of the equipment is not considered. Therefore, there are deviations from the actual project, and the obtained scheme may not be optimal
