[技术讨论]Productivity Formulae of Longitudinal Bilateral Horizontal Wells in Ribbon Shaped Reservoir_张烈辉 [复制链接]

       2009年12月28日，中国石油大学（北京）在读硕士齐成伟发表了带状油气藏中横向水平井和纵向双分支水平井的拟三维产能公式^[1-3]。陈德民等人对带状油气藏中横向水平井拟三维产能公式在生产段完全穿透带状油气藏时的精度进行了理论分析，证实了带状油气藏中横向水平井拟三维产能公式在生产段完全穿透带状油气藏时具有相当高的预测精度^[4]。
        齐成伟公式是国内外首次出现的建立于带状油气藏的水平井产能预测公式，而以往的产能预测公式，如美国著名的Joshi公式、苏联著名的Борисов公式，均默认油气藏边界为圆形^[5-7]。梁峰等人证实蒋廷学公式和程林松公式、邹丹等人证实Joshi公式和Борисов公式，分别为齐成伟导出的圆形油气藏中辐射状分支水平井拟三维产能公式在生产段相接、分支数为1时的退化公式^[8-9]。
        实际水平井近井地带的渗流场较为复杂且渗透率较低，渗流阻力较大^[10-13]。本文将深入研究并试图导出带状低渗透油气藏中纵向双分支水平井在不同完井方式下的产能公式，以提高水平井产能的预测精度。

Abstract: In order to predict productivity of longitudinal bilateral horizontal wells on different well completions in low permeability, ribbon shaped oil and gas reservoirs, the skin factors appeared during the process of drilling and well completion were ****yzed. QI-Chengwei’s formulae were promoted to productivity formulae of longitudinal bilateral horizontal wells in low permeability, ribbon shaped oil and gas reservoirs on the open-hole completion, slotted liner completion and gravel pack completion through equivalent flow resistance method.
Key worlds: low permeability; ribbon shaped reservoir; branched horizontal wells; QI-Chengwei; productivity formulae; slotted liner completion; gravel pack completion

Abstract：Motion of the fluid which flow into or out of cracks, as a theoretical basis for the study of water breakthrough time and cuttings re-injection ,was successfully simulated by utilizing kinematic formula of seepage field excited by a straight crack with finite length and by combining with the transformation from curvilinear orthogonal coordinates to Cartesian Coordinates. In addition, in order to improve the theory, velocity and streamline length were studied. At last, a further research in motion of the fluid which flow into or out of cracks with the influence of oil and water filtration coefficient differences and crack conductivity was proposed for later researchers.
Key words：hydraulic fracturing；straight crack；seepage field；kinematic formula；curvilinear orthogonal coordinates；kinestate；water breakthrough time；cuttings re-injection

文章的翻译有点问题，Longitudinal 是纵向缝，也就是井筒与裂缝平行

“重大突破！！！”
oh MG

张老师？

小师弟很厉害哦~~

我操 又引用齐成伟的公式 他的绝对是假的 盲目引用会有报应的

谢谢！！！

这些东西就莫说了！

看看啊，这个方面不太了解
