我国重点盆地致密油气资源潜力

我国致密油气勘探开发在鄂尔多斯、四川、松辽、准噶尔等盆地取得了一系列新发现和新突破,储量和产量快速增长,是现阶段最现实的非常规油气资源。梳理总结致密油气勘探开发进展,采用三大类七种评价方法,对10个重点含油气盆地致密油气资源进行评价,计算得到致密油地质资源量146.60亿吨,可采资源量14.55亿吨,致密气地质资源量22.88万亿方,可采资源量11.26万亿方。综合分析认为,我国致密油气资源丰富、潜力大,具有良好的勘探开发前景,预计到2020年致密油产量可达300万吨,致密气产量可达550亿方。面对挑战,抓住机遇,要从理论研究、技术攻关等多个方面共同努力,推动致密油气的勘探开发。

Potential of tight oil and gas in major basins in China

Regarding the new discoveries and breakthroughs in tight oil and gas exploration in Ordos, Sichuan, Songliao and Junggar basin, reserves and productions increased rapidly, and tight oil and gas is considered to be the most practical unconventional hydrocarbon resources. Based on the summarizing of new advances in exploration, resources assessment of tight oil and gas in 10 major basins was carried out by using seven methods. According to the assessment, tight oil and gas resources in-place are respectively estimated at 14.66 billion tons and 22.88 trillion cubic meters, and recoverable tight oil and gas resources are respectively estimated at 1.455 billion tons and 11.26 trillion cubic meters. The assessment indicates that tight oil and gas is abundant in China and has a good prospect for exploration. Production of tight oil and gas are respectively expected to be 3 million tons and 55 billion cubic meters. Considering the challenges and opportunities, exploration of tight oil and gas should be promoted by joint efforts form research on theory, key technologies and so on.
