METHOD FOR DEVELOPING A PETROLEUM AND GAS FIELD Russian patent published in 2022 - IPC E21B43/00 E21B43/16 

FIELD: petroleum industry.

SUBSTANCE: invention relates to a method for developing a petroleum and gas field. Method for developing a petroleum and gas field includes predicting and searching for hydrocarbon deposits using topographic maps, conducting a survey by seismic exploration, building a top prospective horizon structural map in order to determine the position of the crests of structures and the map of isolines. The dimensions of the structure along and across the isoline, along the long l and short d axes are determined. An exploration borehole is drilled within the upper isoline. Dip measurements are taken in the prospective horizon top. The total vector of the direction of development of fracturing areas and the acute angle α between said vector and the long l axis of the isoline are determined. The placement of production and injection boreholes along the long l and short d axes is mapped. Boreholes on the short axis are located between boreholes on the long axis. The distances x between the rows of boreholes along the long axis and the distance y between the rows of boreholes along the short axis of the isoline are determined with account for the ratio x/y = l/d·cosα and the cost effectiveness of developing the field. Production and injection boreholes are drilled in order to ensure efficient even drainage of hydrocarbons in accordance with the total vector of direction of fracture porosity.

EFFECT: increase in the effectiveness of developing hydrocarbon deposits.
