Review of exploration and development technologies for heavy oil and high pour-point oil in Liaohe oil region

There are abundant oil and gas,complex geologic conditions and diverse oil types in Liaohe Depression. The exploration and development of heavy oil and high pour point oil occupy an important place in Liaohe oil region. During exploration and development, systematic research about generation mechanism and distribution characteristics of heavy oil and high pour-point oil was conducted. In view of uniqueness of heavy oil and high pour-point oil reservoir, various technical methods were fully used, and some leading techniques for development of heavy oil and high pour-point oil in Liaohe oil region were developed. Good results in heavy oil and high pour point oil development have been achieved. The exploration and development experiences of heavy oil and high pour-point oil were reviewed. The technologies for exploration and development of heavy oil and high pour-point oil in Liaohe oil region were discussed. The existing difficulties in exploration and development of heavy oil and high pour-point oil were analyzed.
