摘要:

提出了利用反褶积算法进行试井解释的方法,研究了试井解释方法反褶积算法的求解过程。以DN1气田DN11井完井测试资料为例研究了反褶积方法在早期地层测试资料解释中的应用。结果表明,反褶积方法可以综合整个测试过程的所有产量、压力信息,从而可以更加充分地利用地层测试资料的所有信息。通过反褶积曲线正确确定了DN11井试井解释模型,求得了基岩裂缝储容比及窜流系数,为后期气田地质模型建立及数值模拟进行开发动态预测提供了重要依据。

Abstract:

The deconvolution interpretation algorithm was applied to early formation of gas well test. The solving process of the algorithm is presented for well test deconvolution interpretation method. The application of deconvolution interpretation method to formation test in Well DN11 of DN1 Gasfield shows that the deconvolution method can provide more much information compared with the conventional well testing interpretation methods, and the interpretation model of the oil well can be correctly determined using the deconvolution-type curve. The deconvolution log-log curve of Well DN11 was used to obtain the storage ratio and inter-porosity flow coefficient of the matrix-fracture system, which would play an important role in the geological modeling and reservoir simulation of DN1 Gasfield.
