| description | The relevance. Increase in the share of hard-to-recover oil reserves among all hydrocarbon deposits leads to the need to develop gas condensate fields with oil rims. Gas with lower density than oil is located above it and forms a gas cap. If gas is produced from this cap, the reservoir pressure decreases. Due to a pressure gradient between the gas cap and the oil rim, oil flows into the initially gas-saturated area of the formation. Some of this oil becomes unrecoverable by traditional methods due to the presence of residual oil saturation. The development of an oil rim and the postponement of the development of a gas cap is not always an economically optimal solution. Therefore, a relevant task is to choose the mode of development of an oil and gas condensate field. Such a choice can be made using hydrodynamic simulation, which has shown itself well in the oil and gas industry.
The main aim of the work is to create a methodology for selecting the mode of development of the field with an oil rim and a gas cap using hydrodynamic simulation.
Objects of the research are gas condensate deposits with oil rims.
Methods. Simulation is based on the use of classical laws of conservation of mass and momentum for a multiphase medium, solved using an implicit finite-difference scheme for pressure and an explicit scheme for phase saturation in hydrodynamic simulator. Several options are calculated for one field with various development modes, differing in the time of transition to joint production of oil from the rim and gas from the gas cap, the oil recovery factor is estimated.
Results. Using a hydrodynamic simulator, the values of the final oil recovery factors for all development modes were obtained. It is established that the highest oil recovery factor is achieved with the initial oil production without the development of a gas cap. It is shown that the later development of the gas cap makes it possible to achieve large values of the oil recovery factor. The introduction of the gas cap into development 15–20 years after the beginning of the development of the oil rim is justified. |
