A study on Suizhong 36-1 oil field acid sludge formation influence factors

Acid sludge is one of the major oil field acidification increased production ineffective. Therefore, the acid sludge formation of influencing factors on improving acidification effect is of great importance. The Suizhong 36-1 oilfield is selected as the research object, a more in-depth study of the acid sludge formed in the acidification process influencing factors. The results show that: With the increase of crude oil in the colloid and asphaltene content, the amount of oleic acid mixture to form acid sludge also increases. Strong acid ionizing out of the higher concentration of H+, the faster of the speed, the forming acid slag trend is obvious. The residual acid pH value increased, the amount of acid sludge also will continue to rise.
