摘　　要：水平井地质储量计算目前尚无成熟的方法,而如何科学、合理的计算水平井地质储量成为水平井开发过程中首要解决的问题。榆林气田长北合作区采用双分支水平井开发,为了准确计算水平井的地质储量,在对水平井泄流模式研究的基础上,通过水平井与直井泄流半径对比分析,提出了将水平井控制体积看做中部砂岩段按椭球圆台体、两端按半圆体的储量计算方法,对长北合作区水平井储量进行实际计算,取得了较好效果。The calculation of GIIP of horizontal well is currently no proven methods,and how to scientific and rational solve this problem is the first development process.Changbei zone of the Yulin gas field is currently dual-lateral horizontal wells.In order to accurately calculate the GIIP of horizontal wells,the horizontal well will be put forward as the central control volume round table by the body,both ends of the semicircular body reserves based on the discharge radius of comparative analysis between the horizontal and vertical wells. We had calculated the GIIP of horizontal wells of Changbei zone and achieved good results.
