Study On The Evaluation Of Gas Potential In Niudong 1 Buried Hill Wumishan Formation

NiuDong 1 buried hill is north China,huabei oilfield after years of efforts of the newly discovered buried hill reservoirs,high buried as deep as 5500 m,the temperature as high as 170 ~ 180 ?,is the deepest buried in huabei oilfield discovered buried hill,the highest temperature of buried hill;It is also the latent mountain gas reservoir of the present comparison,the gas reservoir type belongs to the condensate gas reservoir with the high concentration of hydrogen sulfide and carbon dioxide acidic gas.Natural gas has become the main direction of gas development in modern cities with its clean,efficient features.In recent years,with the rapid development of economy in our country,the natural gas production increased rapidly,the development of our country economy,change the energy structure and improvement of the environment is of great significance.Huabei oilfield at present most ready buried hills,fields and conglomerate gas reservoir are converted into underground gas storage,gradually NiuDong 1 buried hill found beneficial compensate for a drop in north China,huabei oilfield gas production.The research mainly studies through the structure,reservoirs and reservoir characteristics of NiuDong 1 buried hill,confirm the reservoir type of NiuDong 1 buried hill,and also,evaluate the natural gas storability of NiuDong 1 buried hill.The research shows that the buried hill has a certain development potential of natural gas.Therefore,by investigating condensate gas reservoir development,in view of the characteristics of NiuDong 1 buried hill combined with well testing and producing test and a preliminary development plan of NiuDong 1 buried hill has been proposed.The research made clear its development mode,development series of layer system,reasonable deliverability,reasonable gas productivity rate,development well pattern and other technical indicators.Author has some preliminary understandings about the appropriate development technical policies and development plan.This study provides the foundation for the implementation of the deliverbiilty construction of NiuDong 1 buried hill.
