Building A Database Of Underground Gas Storages

This paper, by researching and studying substantive data of underground natural gas storage both here and abroad, at the same time considering our country' condition , studies underground natural gas storage engineering , the main contents are included as follows :1, By researching the construction of underground gas storage both here and abroad, underground gas storage reservoir site selective preference principles are determined , adopting syntheses judgement means of fuzzy mathematics to prefer the reservoir site, and bringing forward scientific criteria of reservoir site selective preference. This paper prefers a better reservoir site from four selectable underground gas storage reservoir site in JiangHan oil field by syntheses judgement means .draws the conclusion that the north site of QianSan step in WangChang oil field is better than the other three selectable reservoir site in rebuilding underground gas storage.2, This paper determines technological preparation and engineering data as well as technological requirement of underground gas storage on the base of depleted oil and gas resource rebuilding for gas storage. This paper analyzes oil and gas resource engineering data of QianSan step north site in WangChang oil field by using its data , gets some engineering data , such as storage capacity, the number of injection and production gas well and the open-flow capacity of injection and production gas well.3,Dynamic injection and production model of injection and production gas well of gas storage is built on the base of studying numerical simulation data of underground gas storage . This paper uses the data of QianSan step north site in Wangchang oil field tosimulate dynamical this site , gets the curve of pressure and capacityof injection and production gas well,and analyzes it.4, This paper adopts syntheses judgement means to prefer gas storage constructing scheme on the base of determined gas storage constructing principle of gas storage , and analyzes a example to demonstrate feasibility that syntheses judgement means can prefer gas storage constructing scheme.5, This paper evaluates underground gas storage on the base of combining the particularity of long-distance transporting pipeline,and gets economic benefit incarnate cost. Understanding to adopt mathematical technique to optimize long-distance natural gas transporting pipeline' s constructing scheme on the base of combining underground gas storage before constructing gas transporting pipeline.This paper's innovations are laid in:To analyze and determine preference principle of gas storage site , adopting syntheses judgement means to prefer gas storage site; To determine engineering parameters of gas storage ; To bring forward gas storage constructing principle .adopting syntheses judgement means to prefer gas storage constructing scheme; To evaluate gas storage by combining particularity of long-distance natural gas transporting pipeline.
