Abstract
Studied and improved is an integrated sand control technology in the entire process of the redevelopment in Shu 3 area, Liaohe oilfield. According to the reservoir geology characteristics and application of perforating technology in the past, developed is a new type of sand control perforator. The perforator is applied in the redevelopment pilot test area of Du 21 block. This new technology is carried out in three stages: drilling and completion, forced-sanding and deep sand control; in these stages together used are sand control perforating technique, sand-pumpcarrying oil production technique and water injection for expansion prevention technique so as to avoid sanding and casing damages. The new sand control perforating technology satisfies integrated sand control specifications in the redevelopment in Shu 3 area, Liaohe, and has better application result. Therefore, it has some reference for the development of perforating technology.关键词
