【摘要】：英臺斷陷深層天然氣勘探自2007年獲得突破后,已成為松遼盆地南部深層天然氣勘探的重點區(qū)塊之一,現(xiàn)已部署4口探井并成功獲得工業(yè)氣流。所以,研究好深層源巖的生烴能力,計算資源量,對未來的天然氣勘探起到重要作用。本次研究對英臺斷陷深層的三套烴源巖開展定性與定量評價,并進行氣源對比,有望對英臺斷陷深層天然氣勘探的下一步工作起到一定的指導(dǎo)作用。烴源巖定性評價表明英臺斷陷深層登婁庫組源巖主要為中等—好源巖,少部分為很好源巖,干酪根類型以Ⅱ2型為主；營城組源巖主要為好—很好源巖,干酪根類型以Ⅱ1型為主；沙河子組源巖主要為中等—好源巖,干酪根類型基本以Ⅱ1-Ⅱ2型為主,通過測井地化進行TOC豐度計算并刻畫登婁庫、營城組和沙河子組TOC等值線圖。三套源巖均處于高成熟和過成熟階段,生油高峰在1900m,生氣高峰在2100m～2900m之間。烴源巖定量評價表明,英臺斷陷登婁庫組登婁庫組總生氣量為4980億方,按照運聚系數(shù)1%～5%計算,其資源量為49.8～249億方；營城組總生氣量85288億方,按運聚系數(shù)1%～5%計算,資源量為852.88～4264.4億方；沙河子組總生氣量27546億方,按照1%～5%的運聚系數(shù),其資源量為275.46～1377.3億方。氣源對比顯示登婁庫組和營城組源巖的天然氣主要供給自身碎屑巖儲層,沙河子組源巖的天然氣主要供給營一段火山巖儲層。登婁庫的有利區(qū)位于北部源巖生烴強度高值區(qū),營城組有利區(qū)基本全區(qū)分布,沙河子組有利區(qū)位于中部和北部生烴強度高值區(qū)與營一段火山巖儲層疊合的區(qū)域。
[Abstract]:Since the breakthrough of natural gas exploration in Yingtai fault depression in 2007, it has become one of the key blocks of deep gas exploration in the south of Songliao Basin. Four exploration wells have been deployed and industrial airflow has been successfully obtained. Therefore, the study of hydrocarbon generation capacity of deep source rock and calculation of resource quantity will play an important role in natural gas exploration in the future. The qualitative and quantitative evaluation of the three sets of hydrocarbon source rocks in the deep layer of Yingtai fault depression and the comparison of gas sources are expected to play a guiding role in the next step of natural gas exploration in the deep layer of Yingtai fault depression. The qualitative evaluation of source rocks shows that the source rocks of the deep Dengloku formation in Yingtai fault depression are mainly medium-good source rocks, a few are good source rocks, the kerogen type is mainly type 鈪，
