GAS GATHERING AND TRANSPORTATION SYSTEM IN GAS FIELDS

摘要

FIELD: oil and gas industry.;SUBSTANCE: system includes a lot of well heads, a lot of gas gathering stations, at least one central booster station for gas gathering and at least one outlet pipeline, in which each of the gas gathering stations is connected to the set of well heads through the corresponding gas gathering branches so that gas inlet from each individual well to a gas gathering pipeline of its corresponding gas gathering stations is provided; a set of gas gathering stations, which includes at least one main gas gathering station and a set of gas gathering substations at least on one level, the main gas gathering station has a possibility of immediate gas transportation to the central booster gas gathering station through the appropriate gas gathering pipeline while each of gas gathering substations has only one parent gas gathering station and has one or more "young" gas gathering stations, and each of the gas gathering substations is connected to its parent gas gathering assembly through its corresponding gas gathering pipeline and has a possibility of gas transportation to a central booster gas gathering station through the parent gas gathering station; and possibility of gas transportation in the outward direction through the outlet pipeline under pressure in the central gas gathering booster station is provided.;EFFECT: improving reliability and providing safe production and environmental protection.;9 cl, 2 dwg
