Embodiment Construction

[0075] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0076] figure 1 It is a method flow chart of a method for determining pipeline volume provided by an embodiment of the present invention, as shown in figure 1 As shown, the method includes:

[0077] Step 101. Calculate the estimated pipeline transportation volume Q of the target pipeline in the target area by using the preset pipeline transportation volume calculation method in the flat terrain area.

[0078] Step 102. According to the estimated pipeline delivery volume Q of the target pipeline, the target pipeline delivery volume Q' of the target pipeline is determined using a correction formula.

[0079] The correction formula in this step is: Q'=Q*K;

[0080] Among them, K is the preset transportation correction coefficient refle...

Abstract

The invention discloses a pipeline transportation capacity determining method and device, and belongs to the technical field of pipeline systems. The method comprises the steps that the pipeline transportation capacity calculating method in a preset terrain flat area is adopted to calculate a pre-estimated pipeline transportation capacity Q of a target pipeline in a target area; according to the pre-estimated pipeline transportation capacity Q of the target pipeline, a correction formula is adopted for determining a target pipeline transportation capacity Q' of the target pipeline; and the correction formula refers to Q'= Q*K, wherein K is a preset transportation capacity correction coefficient for reflecting the environmental factor relation between the terrain flat area and the target area. The pipeline transportation capacity determining method and device effectively improve accuracy of determining the pipeline transportation capacity and are used for determining the pipeline transportation capacity.

Description

technical field [0001] The invention relates to the technical field of pipeline systems, in particular to a method and a device for determining pipeline volume. Background technique [0002] In the process of oil and gas transportation, the pipeline throughput reflects the actual operation of the pipeline. In practice, the pipeline transportation volume may be affected by many factors, such as terrain and air pressure, and there are certain difficulties in estimating and determining the pipeline transportation volume. Therefore, how to accurately determine the pipeline volume has certain practical significance. [0003] In the existing technology, when determining the pipeline transportation volume, two methods are mainly used: numerical formula calculation and numerical software simulation, and one of the calculation formulas such as Weimos formula, Panhandel A formula, and Panhandel B formula can be selected. Calculate and simulate the pipeline environment to determine t...
