Prediction of the indicators of influence process with hot liquid hydrocarbons on gas condensate wells

In the article, temperature and condensation distribution reports were made during the process of periodic injection of liquid hydrocarbons with a temperature greater than the formation temperature into the wellbore zone in gas condensate wells. Propane gas, a liquid hydrocarbon, was used as a solvent. The process of influencing the well-surrounding zone with hot gases occurs under conditions of multi-contact compression of the gas-condensate mixture with propane and propane mixed with dry gases. As a result, in the heated zone, propane completely vaporizes the formation water, while a portion is vaporized and compressed with gas. The removal of retrograde condensate by first injecting hot propane-butane fractions and then hot gases is considered an effective and feasible approach to increasing gas condensate well productivity. This method enhances hydrocarbon recovery by preventing condensate accumulation, which can hinder gas flow. It significantly reduces the required volume of dry gas injection, thereby improving the overall efficiency of the process. By influencing the wellbore zone with hot gases, it is possible to optimize resource consumption while maintaining high productivity. Compared to isothermal injection, the proposed method allows for a 2.5–3 times reduction in the volume of working agents while achieving similar production levels. This approach not only enhances economic feasibility but also minimizes operational costs and environmental impact, making it a promising technique for gas condensate field development. Overall, the findings suggest that controlled thermal injection can serve as an efficient strategy for maintaining and even enhancing gas production rates over extended periods, ensuring the sustainable development of gas condensate fields.
