String structure, working principle, technical parameter, applied scope and process characteristics of three techniques of eccentricity and pulling with separated layer injection,separated layer injection with concentric integration, surface separated layer injection are introduced in detail. Through field applications, these three basic sub-injection processes while matched with new technologies such as the constant flow blockage,three parameters tester, compensator of flexible tubing can meet the need injection wells of Dagang oilfield, which plays an important role on stabilizing oil water control and resolving and curbing the growing contradiction between layers.
