反褶积试井解释方法在东海油气田中的应用

海上油气井由于测试时间短,利用常规试井解释方法往往难以较准确反映地层边界特征,而应用反褶积算法进行试井解释,基于叠加原理截取更长的压力生产史参与计算,能够得到更长时间的压力响应,从而获取更多的储层信息,为储层边界的识别提供可靠的依据,对不稳定试井解释技术是一个很好的补充和完善.尝试利用东海有限的油气井测试资料利用反褶积方法进行解释和分析,并对其应用进行归纳和总结.这对东海的勘探开发、对反褶积方法本身发展均有较重要的参考价值.

Application of Deconvolution Well Test Interpretation Methods in East China Sea Oil and Gas Fields

Due to short test time of offshore oil and gas wells, it is very difficult to use the conventional well test interpretation methods to reflect accurately the characteristics of formation boundary. By using the deconvolution algorithm for well test interpretation, with long pressure history of production for analyzing well testing on the basis of superposition principle, long time test pressure response can be obtained. This can provide more information about reservoirs and reliable basis for identification of reservoir boundary, being complement and improvement for the unstable well test interpretation method. By using the deconvolution method, with limited oil and gas well test data of the East China Sea, the application results have been summed up. The deconvolution method has important value for exploration and development in East China Sea.
