水平井已成为低渗透油气田转变开发生产方式、提高单井产量、快速建产的主体技术。而水平井的试井解释方法还不完善。通过对水平井试井理论和解释模型的阐述，分析水平井系统的流动规律，以及曲线特征的影响因素，探讨低渗透气田水平井试井解释方法，提高水平井试井解释结果的准确性，为低渗透气田水平井的高效开发起到指导性作用。

In well test process,gas well productivity can not be calculated normally when a traditional productivity analysis method is used.On the other hand,ideal fitting curve can not be obtained when a conventional well test model is used for reservoir evaluation.Therefore,productivity analysis method needs to be improved and new well test model shall be applied for well test result interpretation so as to obtain reasonable single well productivity and accurate reservoir parameters.Applied is superposition correction method and introduced is pressure square calibration factor Cj to demonstrate the information of certain well,which can not be treated by traditional productivity calculation methods,the two methods have very good treatment ability and their calculation results have higher accuracy.For questions occurring in well test result interpretation of certain well,applied is the new well test model for interpretation and obtained are reasonable interpretation results finally.

The horizontal well has become the main tech in low permeability oil and gas field to transform the development mode of production, improve per well production, rapidly construct well yield, but well test interpretation for horizontal well is not efficient and reasonable development. Through illustration of well test theory and model analysis of the horizontal well, flowing pattern of the horizontal well system and influenced factors to the curve characteristics in low permeability gas reservoir have been analyzed, horizontal well test interpretation method has been discussed to raise accuracy of the level of well testing interpretation for low permeability gas reservoir, which plays a guiding role for efficient development of horizontal well.

靖边气田试井解释主要应用基础模型进行解释,对试井软件中的扩展模型应用较少,本文应用2-Φ径向复合模型和双层双渗模型对实际工作中遇到的复杂试井曲线进行了完美拟合,并结合地质情况验证解释结果的准确性,为今后试井解释工作提供参考。

Conventional well test analysis has become matured as to application in homogeneous reservoir and single-phase flow, while theories and methods of numerical well test analysis are rarely used as a new technology. In this paper, some features and current applications of numerical well test analysis were briefly introduced, especially applications in complex gas wells in various kinds of reservoir, such as Jingbian, Yulin, Wushenqi, Sulige gas fields. The process of conventional and numerical well test analysis was illustrated in detail with comparison of the analysis results from the two methods. These summaries are very useful to improve application of well test analysis technology and extend application of numerical well test analysis.
