摘要
酸化工艺技术是新井试油、油田开发过程中油井解堵和改造油层的重要措施。根据华北碳酸盐岩油藏的主要地质特征和油田开发三个阶段的增产、挖潜特点，论述了碳酸盐岩基质酸化工艺技术在不同开发阶段的应用。即针对各个开发阶段的挖潜特点，选择合理的酸液配方和施工工艺参数，或结合机械卡水、化学堵水和深抽提液等措施，进行配套施工，能取得理想的增油、挖潜效果。
Acidizing technology is an important measure for relieving damage and stimulating formation during new well test and throughout oilfield development. In accordance with the main geologic characteristics of Huabei carbonate reservoir and the features of increasing production and exploiting potentia1ities during three oilfield development periods, this paper discusses application of acidizing technology for carbonate matrix in different development periods. That is, in accordance with the features of exploiting potentialities in each development period,to choose proper formula of acidizing fluid and operation process parameters,or combined with mechanical water packing off, chemical water control, deep seated pumping and lifting and other measures to conduc matching operation, the ideal results of increasing production and exploiting potentialities are possible to berealized.
