Abstract

The invention discloses a drainage system and a drainage method and belongs to the field of oil-gas production and development. The drainage system comprises a gas production tree, a first drainage pipeline, a second drainage pipeline and a third drainage pipeline vertically communicating to the gas production tree successively, and a sludge collecting part. The second drainage pipeline is vertical to the ground. The sludge collecting part is connected to the lower end of the second drainage pipeline for collecting solid impurities discharged by the gas production tree. The drainage system guarantees smooth operation of drainage work by arranging the gas production tree, the first drainage pipeline, the second drainage pipeline and the third drainage pipeline. By arranging the sludge collecting part and connecting the sludge collecting part to the lower end of the second drainage pipeline, the solid impurities in produced water are collected, and a condition that normal production of acoal-bed gas well is affected as drainage pipelines are blocked is avoided.

Description

technical field

[0001] The invention relates to the field of oil and gas production and development, in particular to a drainage system and method. Background technique

[0002] During the production and development of coalbed methane, solid impurities such as clay and coal powder often appear in the wellhead drainage pipeline. At a certain temperature, the solid impurities will form blockages in the drainage pipeline, blocking the row of pipelines, and affecting the normal operation of coalbed methane wells. Production.

[0003] Therefore, it is very necessary to provide a drainage system capable of avoiding blockage of the drainage pipeline. Contents of the invention

[0004] Embodiments of the present invention provide a drainage system and method, which can solve the above technical problems. The specific technical scheme is as follows:

[0005] On the one hand, an embodiment of the present invention provides a drainage system, the drainage system comprising: a gas ...

Examples

Embodiment Construction

[0039] 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.

[0040] It should be noted that the following X-mas tree 1 refers to the main pipeline of X-mas tree 1, and its direction is always perpendicular to the ground.

[0041] On the one hand, the embodiment of the present invention provides a drainage system, such as the attached figure 1 As shown, the drainage system includes: a gas tree 1 , a first drainage pipeline 2 , a second drainage pipeline 3 , a third drainage pipeline 4 , and a silt collection member 5 that are vertically connected to the gas tree 1 in sequence. Wherein, the second drainage pipeline 3 is perpendicular to the ground; the silt collecting part 5 is connected to the lower end of the second drainage pipeline 3 for collecting solid impurities discharged from the gas tree...
