Abstract
|
Ansai Oilfield Layer 2 oil reservoir properties by the impact of serious corrosion wellbore, using oil bar corrosion cracking after 3 years,5 years after tubing with perforation due to corrosion caused by oil well sucker rod fracture accounted for a small number of 30 workover % or more,replace the oil lever in more than 20,000 meters,5,000 meters above the pipeline, for maintenance and replacement costs a lot in each year.2 Select the length of Ansai oil exploration blocks drainage layer to carry out research work sheets. Corrosion of the wellbore through the analysis and evaluation of the effectiveness of existing anti-corrosion measures to explore the effective measures in a comprehensive wellbore corrosion process and to screen for the fluid nature of the metal corrosion inhibitor, corrosion inhibitor to determine the economic and reasonable use of the type and filling way, and to determine the best use of corrosion inhibitor concentration, dosing technology designed to effectively slow the flow of underground pipes, the corrosion rate of bars, extension tubes, bar life, reducing rod fracture wells, workover operations to reduce the number of The purpose of cost savings, efficient development of the field is of great practical significance and economic benefits.
