靖边气田马五地层气井出水机理初探

靖边气田下古生界马五1＋2气藏是靖边气田的主力气藏，但其地层水在横向上呈块状或透镜状分布，无连片水体，气藏无统一的气水界面。多数井具有气水层共存的特点，气水关系不清。但在一些区域或井区，地层水又相对集中的产出，产水量不大、水体不活跃，具有独特的特征。本文简要研究了该气藏的气水分布特点、产水气井动态分析以及气井出水机理分析研究，以便保证气田的持续供气能力。

PRIMARY STUDY ON WATER-PRODUCING MECHANISM OF MAWU FORMATION JINGBIAN GASFIELD

Mawu1+2 gas reservoir is the leading reservoir of Jingbian gas field,but the distribution of the formation water is presenting block or lens in transverse direction.There is no waters in block together and no unified gas-water interface.Most wells have the characters of coexistence between gas and water,and the relationship between gas and water is not clear.But in some areas or well blocks,there are some special characters that formation water is produced relatively centralized and the waters is not active...
