Oil field horizontal well sectioned free corresponding control oil production process

摘要: The invention discloses a horizontal well sectioned free corresponding control oil production process. problem that in the prior art, yield is low solved. Specifically, firstly, according to geologic plan, an and water are divided into N layer sections correspondingly; then technique pipe columns lowered sequence from root end finger end, through pressing mode, first section of exploited, other closed; injected till content increased be 98%; sequence, ofthe exploited. According process, sequential adjusting production, generates flow surrounding effect, injecting quantity all increased, thus effect more obvious, swept volume enrichment not driven near-well zone driven, decreased, increased.
