    FEASIBILITY ANALYSIS OF UTILIZATION OF WASTE GYPSUM MINE FOR CRUDE OIL STORAGE

    • With the rapid increase of energy consumption in China, the construction of the crude oil reserves is urgent. At present, ground storage tank is commonly used to store crude oil at home and aboard. There have been many ground storage tanks over the word. The technology is mature and the construction period is short. The other method is the underground storage of crude oil. In China it has been a rising technology in recent years. Currently granite rock mass is generally selected as building mass in China. Underground construction of underground structure has a strict requirement on the rock conditions. Several underground storages under construction are distributed in the eastern coastal granite areas. This paper mainly studies the feasibility of using waste storage crude gypsum mine. Some engineering geological characteristics and hydrogeological characteristics of gypsum mines in China are studied. The stability analysis of surrounding rocks, oil immersion test, and comprehensive analysis of crude oil reserves have been carried out. Preliminary findings indicate that the plaster has good geological conditions of mining area. Intensity of regional stability is examined with no fault. Gypsum ore body on average is 458.42meters thick. The average saturated uniaxial compressive strength of gypsum mine sample is 55.45MPa. Gypsum ore body has the grade Ⅱ on rock mass quality. The studies cover the room and all kinds of roadway surrounding rock stability. Gypsum mine bibulous rate ranges in 0.014% ~0.036%.The oil absorption rate range is 0.060% ~0.060%.Meanwhile gypsum mine reserves of crude oil has the advantages of low land saving, investment province, operating capacity, high safety, less environmental pollution, long service life. Through the above studies, this paper has concluded that the gypsum mining area are the basic conditions of construction of underground crude oil reserves.
