【摘要】：隨著頁巖氣國(guó)家級(jí)示范區(qū)的建設(shè),中國(guó)頁巖氣進(jìn)入規(guī)模開發(fā)階段;到2016年12月,長(zhǎng)寧-威遠(yuǎn)、昭通和涪陵國(guó)家級(jí)頁巖氣示范區(qū)實(shí)現(xiàn)年產(chǎn)氣量79×10~8 m~3,到2030年頁巖氣規(guī)劃年產(chǎn)量達(dá)到(800~1 000)×10~8 m~3,展現(xiàn)出良好的發(fā)展前景。四川盆地龍馬溪組地層厚達(dá)300m左右,進(jìn)一步識(shí)別出優(yōu)質(zhì)頁巖段,評(píng)價(jià)優(yōu)質(zhì)頁巖儲(chǔ)層特征是開發(fā)階段的首要任務(wù)。依據(jù)筆石帶特征和沉積相演化,將龍馬溪組劃分為龍一、龍二2個(gè)層段;志留紀(jì)早期深水陸棚沉積環(huán)境控制了優(yōu)質(zhì)頁巖的空間分布,巖心觀察識(shí)別出龍一段底部黑色炭質(zhì)頁巖和硅質(zhì)頁巖是優(yōu)質(zhì)頁巖發(fā)育的有利巖相,優(yōu)質(zhì)頁巖具有高有機(jī)碳含量、高脆性礦物含量、高含氣量的特征;優(yōu)質(zhì)頁巖段地質(zhì)儲(chǔ)量豐度集中,平均儲(chǔ)量豐度達(dá)到1.85×10~8 m~3/km~2,是頁巖氣規(guī)模化開發(fā)的有利層位。
[Abstract]:With the construction of the national shale gas demonstration zone, China has entered the stage of large-scale development of shale gas; by December 2016, Changning-Weiyuan,In Zhaotong and Fuling National Shale Gas demonstration areas, the annual gas production is 79 脳 10 ~ (8) m ~ (3), and by 2030 the planned annual output of shale gas reaches to 800 ~ (1 000) 脳 10 ~ (8) m ~ (3), showing a good prospect of development.The formation thickness of Longmaxi formation in Sichuan Basin is about 300m. It is the primary task of the development stage to further identify the high-quality shale formation and evaluate the characteristics of the high-quality shale reservoir.According to the characteristics of graptolite belt and the evolution of sedimentary facies, Longmaxi formation is divided into two formations, Long-1 and Long-2, and the early Silurian deep-water shelf sedimentary environment controls the spatial distribution of high-quality shale.The core observation shows that black carbonaceous shale and siliceous shale are favorable lithofacies for the development of high quality shale at the bottom of Longyi member. The high quality shale has the characteristics of high organic carbon content, high brittle mineral content and high gas content.The geological reserve abundance of high quality shale segment is concentrated, and the average reserve abundance reaches 1.85 脳 10 ~ 8 m ~ (-1) ~ 3 / km ~ (-2), which is a favorable horizon for large-scale development of shale gas.
