长庆靖安油田是典型的整装特低渗透油田。油层渗透率低、孔吼结构复杂，开采过程中更容易堵塞，造成单井产量较低。而长6储层是靖安油田三叠系主要开发层系。为了实现增产目标，采油三厂对所管辖的靖安油田根据不同时期的油藏物性特征、堵塞机理，结合油藏开发动态特征，实施了土酸、分层酸、暂堵酸、泡沫酸、多氢酸等多种稳产增产酸化措施，形成了多元化酸化解堵液体系。通过不断对解堵液体系的评价筛选，最终形成适应于靖安长6油田的增产工艺技术。这对长庆油田持续快速发展奠定了基础。

Changqing Jing'an oilfield is a typical low permeability oil field. Because of low permeability and complex pore and roared Unicorn, oil reservoir development is easy to be blocked, which can lead to low oil production. However, Chang 6 reservoir is the main development layer series in Jing'an oil field. In order to improve production target, many kinds of acidizing fluid systems such as the soil acid, stratified acidification, temporary plugging acid, foam acid, multi-hydrogen acid, have been implemented by the Third Production Plant, which analyzes the reservoir characteristics of the different period, plugging mechanism, combining with oil reservoir development dynamic characteristics. Through constantly screening blocking fluid systems, enhancing production technology has been formed, which can adapt to Chang 6, which has laid a foundation on sustained and rapid development.
