| titleOfInvention | A method for determining the critical liquid-carrying capacity of low-pressure and low-yield liquid-accumulating gas wells in tight and low-permeability gas reservoirs |
| abstract | The invention belongs to the field of gas reservoir engineering evaluation, and discloses a method for determining the critical liquid-carrying capacity of a low-pressure and low-yield liquid-accumulating gas well in a tight and low-permeability gas reservoir. The method includes the following steps: S1: perform a simulation experiment on the gas well to be measured with liquid accumulation, and determine the position where the liquid accumulation gas well to be measured is difficult to carry liquid; S2: obtain the actual production and structure data of the gas well to be measured with liquid accumulation, and determine the to-be-measured gas well determined in step S1 The actual pressure of the liquid-carrying gas well is difficult to carry liquid; S3: establish an n-dimensional spherical liquid-carrying model, and determine the n-dimensional spherical liquid-carrying model according to the statistical data fitting of the liquid-accumulating gas wells and non-liquid-carrying wells in the known gas field to be tested. dimension n, and then determine the n-dimensional spherical liquid-carrying model suitable for the gas field to be tested, thereby calculating the critical liquid-carrying flow rate of each liquid-accumulating gas well in the gas field to be tested, and judging the liquid-accumulation situation of each liquid-accumulating gas well. The method of the invention takes into account the change of the gas-liquid flow pattern under the action of the radial difference of the flow velocity of the pipe flow in the wellbore, and establishes an n-dimensional spherical liquid-carrying model considering the liquid droplet deformation. |
