新疆油气资源开发前景展望

Expectation about the survey and exploitation foreground of oil and natural gas resources in Xinjiang

新疆主要沉积盆地有30多个,总面积90×104km2,油气资源十分丰富,油气资源量365×108t。虽然经过50多年油气勘探历程,已发现80多个油气田,但勘探潜力巨大。笔者从目前勘探形势,油气勘探阶段,资源转化率、形成大油气田地质条件及油气资源发展战略等方面进一步论述新疆是我国油气资源主要接替区。

Xinjiang is located in northwest China, its area is 1.66 × 10^6 km^2. There are more than 30 sedimentary basins with a total area of 9.0 × 105 km^2, the basins are rich in oil and natural gas resources, and the volume of oil and natural gas resources is 3.65 × 10^10 t. After carrying out the difficult surveys since recent 50 years, more than 80 oilfields have been found, in which 9 ones are at large scale, the accumulated positive oil and natural gas reserves is 4.0 × 10^9 t, in which the oil reserves and natural gas reserves are 3.15 × 10^5 m^3 and 8. 776 × 10^11 m^3 respectively. In this paper, it is revealed that Xinjiang will be an important superseding region of oil and natural gas resources in China after discussing the current situation and stage of surveying oil and natural gas resources, conversion rate of oil and natural gas resources, geologic conditions of forming large oilfields, development stratagem of oil andnatural gas resources, etc. A set of characteristic petroleum geology theories and the corresponding technologies are developed. It is believed that the foreground of surveying and exploiting oil and natural gas in Xinjiang will be undoubtedly more splendent under the opportunity of great development in west China during the ＂Eleventh - five Year Plan＂ and the new conditions that the strength of surveying and exploiting oil and natural gas resources in Xinjiang is enhanced by China Petroleum Corporation and China Petrochemical Corporation. Therefore, it can be firmly predicted that Xinjiang will be an important superseding region of oil and natural gas resources in China.
