Technical and technological solutions for limiting water inflow in gas wells with a horizontal bore end

The article considers the main group of reasons for water inflow in gas wells under conditions of abnormally low formation pressures. Approaches are outlined for the conditional allocation of the main stages that the well goes through until it is decommissioned due to complete watering. Two differen...

description	The article considers the main group of reasons for water inflow in gas wells under conditions of abnormally low formation pressures. Approaches are outlined for the conditional allocation of the main stages that the well goes through until it is decommissioned due to complete watering. Two different ways of solving the problem of water inflow limitation in gas wells with a horizontal bore end are examined. The most promising technical and technological solutions for isolating the flooded section of the reservoir are discussed. It is noted that the proposed physicochemical method for limiting water inflow using phase permeability modifiers is more reliable, including when the level of gas water contact increases significantly and there is a high probability of watering the well. To improve formation treatment efficiency and achieve the best performance, mathematical calculations are proposed to determine the minimum installation depth of the modifying screen in the formation, which ensures the achievement of a technical result. The parameters of the modifying composition for preventing water inflow and the procedure for determining the parameters to prevent water inflow in gas wells are given. Some results of applying the technology of water inflow limitation in gas wells with preliminary blocking of the bottomhole formation zone are considered.
