The adjustment and treatment effect of Yun 11 block in Zhongyuan Oilfield is significant

Sinopec News Network reported recently that the recovery rate of Block Yun 11, which was researched and managed by the Dongpu Development Research Institute of the Zhongyuan Oilfield Exploration and Development Research Institute, has increased by 3.
5 percentage points, and the oil recovery rate has increased to 3.
4%, achieving significant results
.

Block Yun 11 is located in the southern part of the ancient Yunji oilfield structure.
The main oil-bearing layer is below the sand.
The fault block has a simple structure, thick oil layers and active edge water.
Before adjustment and treatment, only one horizontal well produced 3.
4 tons of oil per day.
The comprehensive water cut reaches 96.
3%, and it is in the development stage of ultra-high water cut and high recovery program
.

In recent years, in response to the development of barriers and interlayers in this block and the unclear understanding of remaining oil, researchers have carried out fine reservoir description studies and formed a fine description of horizontal well barriers and interlayers, which clarified the remaining oil distribution and potential
.
Deploy a treatment plan for combined development of directional wells and short horizontal wells, and implement one sidetrack and one horizontal well each

Up to now, the cumulative oil production in the block stage has increased by 6,324 tons, and the recovery rate has reached 42.
3%
.
At present, the daily oil production of the block has stabilized at 8.
