The later migration - accumulating pools of hydrocarbon includes types es4 and es3 ; the vertical migration - accumulating pools contain hydrocarbon types es3 and es4 . reservoirs here are distributed along the fault zone and the southern slope of the bonan depression . using the above accumulated data , this study can be used as a basis for new explorative targets in three sand deposits to the north of this study area , providing some likelihood of exploration success 含油面積0 . 7km ~ 2 ,地質(zhì)儲(chǔ)量122 . 5萬(wàn)噸,含油層系沙三中,該塊的發(fā)現(xiàn)是對(duì)墾西地區(qū)北部斷坡帶勘探取得了的新突破,根據(jù)本課題研究認(rèn)為北部斷坡帶上的油藏主要沿斜坡呈帶狀分布的特征,提出了下一步的勘探目標(biāo),對(duì)北部三個(gè)砂體進(jìn)行描述,爭(zhēng)取有新突破。
