- Abstract
With the gradual deepening of Changqing Oilfield horizontal wells, horizontal wells see water phenomenon is gradually increasing, more than 80% of the current water level of high water wells horizontal wells accounted for 25.5% of the total number of open wells. High water level of wells governance means there are horizontal wells to find the mechanical plugging wells, corresponding water depth profile control, bi-directional oil wells plugging technology, by contrast, the current techniques of horizontal wells in Changqing Oilfield high water governance best suited for the corresponding injection wells be deep profile. By reason of the horizontal well see the water, see water type analysis, and ultimately optimize the construction program, citing CDST-01 blocking agent system and application of multi-level multi-round profile control technology to achieve effective governance of the high water level of wells. Field test seven wells, increasing the average single-well oil 4.5t, average moisture content decreased 68%, cumulative oil 3825t, cumulative precipitation 4585m3, a significant treatment effect, provide a reference for the next step Changqing Oilfield high water level governance and reference wells .
