STUDY AND APPLICATION OF ACIDIZING TECHNIQUE IN CHUNHUA OILFIELD

    Graphical Abstract
    • Abstract
  • This paper aimed to further improve the acidizing effect in Chunhua oilfield,lower the cost and increase economic benefit. The laboratory study, comparative analysis and evaluation of acidic fluid and various additives which are currently used in Chunhua oilfield were conducted systematically in view of reservoir and flow characteristics of the oilfield. So various additives and acidic fluid which applied to the oilfield were optimized:acidic stabilizer DTE or ZJH-03, corrosion inhibitor KH-91 or LG-Ⅱ, mutual solvent SCH-1;pretreatment acidic fluid:12%~15%HCl+0. 5%NTS +2%LG-Ⅱ+2%ZJH-03; host acidic f1uid:25%organic acid(FAC) +4%~5%SCH-1. The field application showed satisfactory results with 1:6. 2 input-output ratio and obvious economic benefit.
