MARKET ANALYSIS OF THE NATURAL GAS PRODUCED FROM TALIMU BASIN AND A DISCUSSION ON ITS EASTWARD TRANSPORTATION PLANS

塔里木天然气综合利用现状塔里木油田已探明的气层气还没有开发和利用，油田伴生气利用得也很少。至今先后开发了８个油田，总面积１８３６ｋｍ２，动用石油地质储量２２６１５×１０４ｔ，溶解气储量２４５６２×１０８ｍ３。十年来已累计生产原油１８８６７７×１...

Abstract The Talimu Basin is rich in natural gas resources which was 8.39×10 12 m 3 according to the second resource evaluation in 1993. The cumulative proved gas in place predicted is 631×10 12 m 3, only accounting for 7.52 percent of the total resources. Up to now, in Talimu Basin, the gas bearing formation gas in the oil fields hasn't been developed yet and the associated gas in those has been utilized very little. The Yangtze River Delta, circum Bohai Sea, Central South China are short of energy resources and the East China and Coastal Southeast China are the big markets for natural gas, so that the Talimu gas eastward transportation is of a vast range of prospects. When the predicted mean prices at the city gates in the Yangtze River Delta, circum Bohai Sea. Central West China are 1.2～1.3, 1.1～1.2 and 0.8～0.9 Yuan/m 3 respectively, a larger scale market demand can be reached. The price of the imported liquefied natural gas is 1.6 Yuan/m 3 in the Yangtze River Delta. but the Talimu gas' cost price calculated according to a transportation rate of 10×10 9m 3/a (from Talimu Basin to Shanghai) is about 1.1～1.2 Yuan/m 3. There are three plans for the gas produced from Talimu Basin to be transported to Shanghai: ① independent eastward transportation; ② joint eastward transportation with the gas produced from the Qinghai, Shaan Gan Ning and Sichuan, which transportation rate will reach to 14.3～17.3×10 9m 3/a from 2003 on, the predicted gas price at the city gate in Shanghai being 1.13 Yuan/m 3, the estimated investment being 55.5×10 9 Yuan and the payback period of the investment being 9.43 years; ③ carried eastward transportation to Shanghai, in which the natural gas projects introduced from the New Siberian, the Russian Federation, will be unitedly considered. Although the Plan 3 is good, it is thought that the plan 2 is more feasible because of its relatively low degree of risk and of taking account of the eastward transportation of the natural gas produced from the Qinghai, Shaan Gan Ning and Sichuan, after comprehensively considering those factors as resources, funds and the other risks.
