| This paper through the reservoir analysis, Precrosslinked polymer performance evaluation, system and the formulation of research, field implementation, monitoring and evaluation, good results. For the high moisture content in Jiangsu Oilfield stable oil-water exploration and enhanced oil recovery technology a new way to further meet the oil field in the latter part of the requirements of development. Through research, in accordance with fractured reservoir and geological characteristics of the development, research and development of a fractured reservoir for the Precrosslinked gel composite profile control technology; come up with the second cross-linked gel profile control system and the formula, the introduction of the Precrosslinked swellable-gel particles, developed for Jiangsu Oilfield Yang Xiangjiaba, the two piers Tong Precrosslinked gel composite profile control system and a formula; interior design evaluation apparatus, established a pre-crosslinking polymer evaluation Research system through the reservoir analysis, optimization test wells group, in numerical simulation and test mode of study to determine reservoir programme, the technology programme, field implementation of two test wells group, track and monitor the results and comprehensive evaluation. Application of the success of the scene, Yang 10-3 oil wells by a total of 3169.9 tons.
