摘　　要：为适应我国低渗透油气藏水平井压裂的发展,结合低渗透油气藏地层特征,在现代不稳定试井理论的基础上,综合应用拉氏变换、镜象反映、叠加原理、Green函数、Newman乘积等技术,推导出复杂边界条件下考虑井储和表皮的多级压裂水平井试井解释模型拉氏空间解析解。在这一理论基础上,利用Visual Basic 6.0语言编写了多级压裂水平油气井试井解释软件(考虑压裂裂缝条数在15条以内)。利用自编软件,解释了一口压裂水平气井的压力恢复资料,解释结果与Saphir 4.10软件基本一致,验证了该软件的准确可靠性。该解释软件已在现场成功应用,为低渗透油气藏不同边界多级压裂水平井的试井解释奠定了基础。In order to adapt to the development of horizontal well fracturing of low permeability reservoir,combined with the feature of low permeability reservoir formation,on the basis of modern theory of unstable well test,the integrated application of Laplace transform, mirror reflection,the superposition principle,the product of Green function,Newman,technologies such as the complex boundary condition were deduced considering well store and skin multistage fracturing of horizontal well test interpretation model of the Laplace space analytic solutions.Based on this theory,using Visual Basic 6.0 language to write the multi-stage fracturing horizontal oil and gas well test interpretation software(considering fracturing fracture number within 15).The self-made software can be used to explain a mouthful of fracturing pressure buildup data of horizontal gas well,explain the results are basically identical with Saphir4.10 software,verifies the accuracy of the software reliability.The interpretation software has been successfully applied at the scene,for different boundary multi-stage fracturing of low permeability reservoir well test interpretation of horizontal well laid a foundation.
