This invention relates to oil and gas
field development technology and discloses a quantitative comprehensive evaluation method for the oil stabilization and water
control effect of
horizontal wells. The method includes: determining whether the target water control well is a producing old well or a new well; collecting relevant operating parameters of adjacent wells at the same oil column height and formation level before and after the application of the water control technology, based on whether it is a producing old well or a new well; collecting relevant parameters required for evaluating the
economic benefits of water control in a single well; evaluating the
impact of the water control technology on oil and
water production by comparing the
water production index and
water cut, using indicators such as the effective period of water control, increased
oil production, and changes in
water production, and evaluating the water
control effect; conducting a single-well water control
economic evaluation based on the water
control effect; and comprehensively evaluating the water control effect and economy of the horizontal well. Using the method provided by this invention, a quantitative comprehensive evaluation of the water control effect is conducted from the perspectives of increasing
oil production, stabilizing
oil production, controlling water, and economics, effectively evaluating the oil stabilization and water control effect and economy of
horizontal wells, and effectively guiding the design of water control schemes and
process selection.
