METHOD OF DEVELOPMENT OF MULTIBED OIL DEPOSITS Russian patent published in 2008 - IPC E21B43/16 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to oil and gas industry, particularly to methods of development of multibed oil deposits. Method includes selection of objects for operation, boring of producing and pressure wells for selected objects, pumping of displacement agent into pressure wells and oil withdrawal from producing wells. According to the invention operational objects -well cells- are selected assuming development of all beds of geological cross-section. Then the value of output of a cell of wells is determined and a version of integration of beds into selected operational object of development is established. At that complete separation of beds into independent objects, integration of all beds into one object of development and integration of part of beds are considered. For each of considered version the value of output is determined on base of different analytic formulas. After that the optimal version of separation of beds into independent object of development is chosen on criterion of facilitating maximum value of cell output of the well and minimal development duration at successive bringing of objects into development from bottom-up.

EFFECT: facilitating maximum oil extraction at minimal costs of capital investments and current costs.
