Based on Landman variable density perforation model, a horizontal well variable-density completion coupling model is derived under non-homogeneous formation conditions. And an actual well is taken for example to calculate the production fluid profile of horizontal well under different perforation densities. The results show that the production fluid profile of the high and low permeability section tends to be even with the decrease of the perforation density of the high-permeability section. Based on the coupling model, optimization methods for the variable-density completion of horizontal well under uneven stratum conditions are put forward. The production fluid profiles of optimized perforation model, actual perforation model, and even perforation model are compared. According to the results, the horizontal well corresponding to the optimized perforation model is with the most balanced inflow profile.

Water Coning

When horizontal wells are used to exploit reservoir with bottom water, oil wells water breakthrough prematurely due to water coning, water-free oil recovery is reduced. The reason of the formation of horizontal well water cone is analyzed. Then analysis of the mechanism using balanced screen pipe to inhibit bottom water coning in horizontal well is completed. According to the existing screen pipe size, screen configuration is optimized. Horizontal section pressure distribution is controlled by the balanced screen pipe, and then flow of horizontal well sections is adjusted. Bottom water coning speed of all well sections is controlled. An example is calculated by the software which established and the result shows that optimization method can improve water-free oil recovery.

Fuzzy Logic Control (FLC) is a reliable control system for controlling nonlinear systems, but to obtain optimal fuzzy logic control results, optimal Membership Function parameters are needed. Therefore in this paper Particle Swarm Optimization (PSO) is used as a fast and accurate optimization method to determine Membership Function parameters. The optimal control system simulation is carried out on the automatic steering system of the vehicle model and the results obtained are the vehicle's lateral motion error can be minimized so that the movement of the vehicle can always be maintained on the expected trajectory
