Abstract

Due to special sedimentary environment,Sebei No.1 gas field formed vertical distribution with frequent alternative deposition of sand and shale.As a Quaternary unconsolidated sand gas field,it widely distributed mud sandwich，which has certain thickness and permeability.Based on the analysis of lithology,distribution and permeability of Sebei gas field interlayer,the author believes that mudstone barrier is well developed,with some water content.Water channeling of claystone barrier is the main source of water breakthrough in accordance with the status of water production.Therefore as to water control and precaution it is very important that the author researches the characteristic of interlayer and its operation on water breakthrough.

Key words： Sebei No.1 gas field; Interlayer; Water channeling
