摘要

Horizontal well technology is a technological revolution in oil industry, and it is one of the most important methods of thick layer sustainable production and marginal low permeable formation exploitation in Daqing Oilfield. Usually, horizontal wells will suffer damage during the course of drilling, completion and production due to the mud and other organism’s pollution. Therefore, acidizing is an effective method to improve conductivity near the wellbore and enhance overall production. However, commingled acidizing cannot guarantee acid being pumped into polluted intervals uniformly owing to long horizontal length (583.7m on average) and heterogeneity formation.
