Complete Operation Information Assisted the Leakage Control of Qiongzhusi Formation in Zhongjiang-Penglai Gas Area
The existing plugging methods in Zhongjiang-Penglai gas area are high.To this end,138 geological engineering parameters were extracted from the field data,the characteristic coefficient of all factors on the leakage rate was calculated,and 12 main control factors were selected.When testing the formation fracture scale of 0.008～0.13 mm,the contribution coefficient of 6 drilling fluid performance master factors to the leakage rate is consistent with the calculated value of the mine.To guide the introduction of 0.001～0.01 mm nanoactive particles,the success rate of two wells in the field was 80%,and the consumption of single leakage treatment decreased by 68.60%.The study shows that the complete operation information method can improve the matching accuracy of complex formation plugging means,improve the construction efficiency and improve the economy of measures.
