Embodiment Construction
[0031] The invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.
[0032] Such as figure 1 As shown, a wellhead sampling method for oil and gas wells, the method requires the use of sampling equipment to change the formation fluid flowing in the horizontal direction into a vertical flow through the sampling equipment, and pass a filter and mixing device in the vertical direction to realize the non-uniform flow of fluid Relatively uniform distribution and flow. After uniform flow, a certain amount of samples are taken at different positions of the circulation channel by using a retractable sampling probe until the special sample bottle is filled. The sampling device includes: an inlet 101, which At one end of the pipeline, the other end is vertically connected with another pipeline through a pipeline connector to form an inlet 101, and the inlet 101 ...
