Research On Analysis And Management Of High Moisture Content Wells Of YuJia Wan Area Of ZiBei OilfieId

The Yanchang reservoir of ZiBei Oil Production Plant is typical of low permeability, low abundance, low-yield, high water content of the "three low and one high" reservoir. The comprehensive moisture content of YuJiaWan oil region is more than80%. By measuring the production, oil recovery techniques such as water testing, combined with logging, logging and other geological data analysis, the main causes of high moisture content of YuJiaWan area of ZiBei oilfield include small reservoir pore, large surface area, low permeability; seepage Darcy’s law does not follow the law, with starting pressure gradient; elastic energy is small, the use of natural energy of mining pressure and decline rapidly; oil production capacity and water absorption capacity, and well see the effect of slow water; well see the water liquid production (oil) index dropped significantly; fractured low-permeability sandstone oil fields, water wells along the direction of channeling cracks, severe flooding; oil source is inadequate. Finally, are given the appropriate countermeasures.
