Abstract: Combining the situation of producing well, a technology of complex control profile using ZYC-940 high temperature organic gain was developed via the analysis and comprehend the contrary of Liu 62 block. The integration and matching technology of water shutoff, profile control, oil displacement and formation protection was used, and the effect of increasing oil producing and decreasing water producing was achieved. The successful application of the technology using in Liu 62 lower penetrate sandstone reservoir is a example for the seem reservoir.
