Flow pattern character analysis on ultra-deep flowing well in Tahe Oilfield;

塔河油田超深自喷井流态特征分析

The interpretation technique and software about flowing well testing data with downhole flow pressure rising are completely blanks at home and abroad.

自喷井流压上升的测试资料解释方法与软件在国内外是空白,针对这一情况,建立了变表皮系数、变形双孔介质、高速非达西渗流的数学模型与数值模型,并研制了解释评价软件,它可解释其它试井分析软件不能解释的自喷井流动期井底压力上升的测试资料,且能得到随时间变化的表皮系数及气井的真实绝对无阻流量。

Analysis is made on the basis of working practice on how to solve the conflicts between domestic codes and the requirements of foreign sides (foreign codes),with stress put on the discussion about the designing of automatic sprinkler system.

本文结合工作实践 ,对在外商独资企业厂房的消防设计中 ,如何处理国内规范与外方要求(国外规范)的问题进行分析 ,重点讨论了自喷系统的设计。

This paper explained that the arrangement of the sprinkler heads shall be determined through calculation of water injection strength,proposed two methods for the design calculation of medium_risk automatic sprinkler system,and pointed out that the rectangular action range method is more suitable for the actual fire fighting.

阐述了喷头布置应按喷水强度通过计算确定； 介绍并分析了中危险级自喷系统设计计算的二种方法，指出长方形作用面积法更符合实际火灾情况。
