Abstract: A method for facilitating paging policy differentiation, performed by a Session Management Function (SMF) is provided. The method includes determining that a paging policy differentiation feature is supported by a User Plane Function (UPF) (325). The method includes sending, toward the UPF (325), a message instructing the UPF (325) to insert a Paging Policy Indicator (PPI) value (110) into downlink packets based on a Differentiated Services Code Point (DSCP) value (106). The message includes DSCP-to-PPI control information.

Abstract: The present disclosure provides a method for determining effective storage capacity of a gas storage reconstructed from a water-flooded volatile oil reservoir. The method includes: determining an oil reservoir water flooding recovery ratio; determining crude oil production extracted only due to a water flooding effect in an oil reservoir development process; determining an oil-bearing pore volume of a flooded zone of a reservoir influenced due to the water flooding effect and an oil-bearing pore volume of a pure oil zone of a reservoir not influenced due to the water flooding effect corresponding to its original state before an oil reservoir is put into development when the gas storage is reconstructed from the oil reservoir; determining an effective pore volume for gas storage; and computing the effective storage capacity of the gas storage reconstructed from the water-flooded volatile oil reservoir.

Abstract: A method for predicting an evolution law of a rock mechanical stratum of a fractured reservoir is provided. A three-dimensional heterogeneous model of mechanical parameters of an intact rock is built by means of a core experiment, logging calculation and seismic inversion; a three-dimensional discrete fracture network geomechanical model is built by means of field observation; effects of fracture parameters on magnitudes and anisotropy of mechanical parameters of a fractured rock mass are analyzed by means of numerical simulation; and a paleo-stress field, and a fracture density and occurrence at different periods are simulated in successive cycles in combination with a relation between the fracture parameters of a reservoir and rock mechanical parameters as well as a stress field, and a migration law of the rock mechanical stratum under the control of a tectonic factor is interpreted.
