1、中國(guó)非常規(guī)油氣資源【摘要】常規(guī)、非常規(guī)油氣資源具有成因聯(lián)系和共生特征。油氣資源的空間分布規(guī)律性很強(qiáng)。源巖層系(區(qū))內(nèi)主要富集有頁(yè)巖氣、頁(yè)巖油、煤層氣和油頁(yè)巖,其中前三者在國(guó)外已實(shí)現(xiàn)規(guī)?;_(kāi)發(fā),國(guó)內(nèi)的煤層氣開(kāi)發(fā)已經(jīng)取得進(jìn)展,頁(yè)巖氣開(kāi)發(fā)正在起步,頁(yè)巖油開(kāi)發(fā)還在探索,油頁(yè)巖規(guī)模化開(kāi)發(fā)面臨較大的環(huán)境問(wèn)題,應(yīng)關(guān)注開(kāi)發(fā)新技術(shù)研究。運(yùn)移層系(區(qū))內(nèi)主要聚集致密油氣、水溶氣和部分低滲油氣,致密氣和低滲油氣在國(guó)外已規(guī)?;_(kāi)發(fā),國(guó)內(nèi)在鄂爾多斯、四川等幾個(gè)盆地已大規(guī)模開(kāi)發(fā)。圈閉層系(區(qū))主要聚集常規(guī)油氣、重油和低滲油氣,這些油氣資
2、源均已大規(guī)模開(kāi)發(fā)。散失區(qū)為油砂的主要發(fā)育區(qū),國(guó)內(nèi)油砂品質(zhì)較差,開(kāi)發(fā)有一定難度。繼常規(guī)油氣、致密氣和煤層氣資源之后,頁(yè)巖氣、頁(yè)巖油是我國(guó)最現(xiàn)實(shí)的待開(kāi)發(fā)非常規(guī)油氣資源。我國(guó)非常規(guī)天然氣資源潛力遠(yuǎn)大于常規(guī)天然氣,國(guó)家應(yīng)制定長(zhǎng)期發(fā)展規(guī)劃,加強(qiáng)探索性研究和技術(shù)準(zhǔn)備,這是我國(guó)非常規(guī)油氣資源發(fā)展和提高油氣資源自給能力的關(guān)鍵?!続bstract】Conventionalandunconventionaloilandgashaverelationshipsrelatedtotheiroriginandhavecharacter
