The ultra-low permeability K reservoir first showed oil in well A in 1997 and entered rolling industrial development in 2020. Up to now, 7 blocks have been deployed and deployed, with geological reserves of 532.37 × 104t, from the overall development effect, the difference is large, and the production decline is faster. Common fracturing reconstruction is difficult to form effective use; Conventional water flooding adjustment has poor effect on oil Wells, so conventional water flooding measures have poor effect on the development of ultra-low permeability K reservoir. In this paper, through the exploration of the new nano oil displacement technology, we find out the effective measures to tap the potential technology for the ultra-low permeability reservoir, and achieve the purpose of increasing oil and improving reservoir utilization.

摘要

The ultra-low permeability K reservoir first showed oil in well A in 1997 and entered rolling industrial development in 2020. Up to now, 7 blocks have been deployed and deployed, with geological reserves of 532.37 × 104t, from the overall development effect, the difference is large, and the production decline is faster. Common fracturing reconstruction is difficult to form effective use; Conventional water flooding adjustment has poor effect on oil Wells, so conventional water flooding measures have poor effect on the development of ultra-low permeability K reservoir. In this paper, through the exploration of the new nano oil displacement technology, we find out the effective measures to tap the potential technology for the ultra-low permeability reservoir, and achieve the purpose of increasing oil and improving reservoir utilization.
