根据水平井三维渗流的特征,底水油藏中的水平井渗流可分为早期径向流阶段和晚期稳定流阶段。本文以TKxxDH井为例,利用水平井的不稳定试井分析理论,对比分析了前后两次的压力恢复试井资料。分析表明:两次关井的试井双对数曲线形态基本相同,均反映出水平井在底水油藏的渗流特征,这与该井的测井结果及试采反映的情况一致。这为底水油藏中水平井的试井分析提供了可借鉴的经验。 According to the characteristics of 3D horizontal seepage, the horizontal well in bottom water reservoir can be divided into early radial flow stage and late stable flow stage. In this paper, taking TKxxDH well as an example, the pressure well testing data of two wells before and after the well are analyzed by using the theory of unstable well testing in horizontal wells. The analysis shows that the double logarithmic curve shape of the two shut-in wells is basically the same, which all reflect the seepage characteristics of the horizontal well in the bottom water reservoir, which is consistent with the well logging results and the test recovery. This provides a reference for well test analysis of horizontal wells in bottom water reservoirs.
