Introduction The 2+3 reservoir are two of the important sets of oil and gas reservoir intervals in Pucheng Oilfield.The latest resources assessment result indicated that oil-gas resources is plentiful where total petroleum resources is1298.24×104 tons and that of nature gas is 17.31×108cubic meters.Since they were put into exploration and development,2+3 reservoir in south district of Pucheng Oilfield had been drilled in 109 wells.67 wells have obtained the oil and gas flows.However,exploration of the 2+3 reservoir is complicated and stable oil production is difficult to be maintained in some wells in the discovered oil fields.The most essential reason for this,except for the complex geological

The 2＋3 reservoir are two of the important sets of oil and gas reservoir intervals in Pucheng Oilfield. The latest resources assessment result indicated that oil-gas resources is plentiful where total petroleum resources is 1298.24 × 10^4 tons and that of nature gas is 17.31 × 10^8 cubic meters.
