Abstract:

Minhe basin, located in the boundary between Gansu and Qinghai, abounds in oilgas resources through over 70-year’s exploration. However, the study and exploration is still at a low level. This paper lists lots of oil evidences in surface in field, and carries out a study on oil reservoir in two oilfields with results of oil 3.02×10⁸ t and gas 493.83×10⁸ m³ through basin simulation. This basin, of big oil-gas potential, is one of favorable oil-gas basins to be developed. It is recommended for government and oil-gas companies to do more studies and to invest more in Minhe basin. And these two discovered oilfields shall be submitted to National Reserve Committee with explored reserve and shall be put into operation.

Key words:

摘要：

民和盆地位于甘肃与青海交界处，经历了70余年的勘探，具有丰富的油气资源。但由于种种原因，研究和勘探开发程度很低。本文列举了大量野外油苗露头,对钻井显示和已发现的2个油田，开展了成藏条件分析，通过盆地模拟，估算资源量3.02×10⁸ t，天然气资源量493.83×10⁸ m³。认为该盆地具有较大的油气资源前景，是目前国内未投入开发的最有利含油气盆地之一，建议政府和石油企业对全盆地加大研究力度和勘探开发投资，同时对已发现的2个油田向国家储委上交探明储量，投入正规开发。
