Research and Application Status of Compound In-depth Profile Modification Agents in China
In-depth profile control technology is a significant approach for fields to controlling water and increasing production in the intermediary-later production stage of oilfield with high water cut,and the in-depth profile modification agent is one crux of it. Currently,the in-depth profile modification agents applied commonly in oilfields include traditional simplex agents and new compound agents. However,it has become increasingly difficult for the traditional simplex agents to satisfy fields production demand ,while the compound in-deep profile modification agents perform greater adaptability, commercial value and research necessity. In this paper, the major simplex in-deep profile modification agents used in oilfields were introduced,and then the indoor research progress and application status of various compound agents were summarized, including the active mechanisms, synergistic reaction mechanisms, indoor performance evaluation and field test situation. And the development expectation of compound in-deep profile modification agents was discussed.
