应用Petrel进行储量计算的实践与认识

摘要

Reserve volume is the comprehensive evaluation of oil - gas field exploration and development, as a conse- quence, the rationality of reserve calculation affects definitely an oil field exploitation and development decision. The re- serves calculation method, which is based on the high precision tridimensional geological model, can be used to deal with the issues that the reserve parameters are difficult to correctly acquire when estimating complex reservoir' s reserves in terms of traditional volume method. In addition, the method more accurately reflects the distribution of reserves. To take Xinli - Xinbei area as an example, the reserves value is more objective and accurate by using Petrel calculation method, which is based on the high precision tridimensional geological model. The reservoir evaluation, which is conducted by a combination of calculated reserves value and reserves abundance value, and other related parameters, provides the geolog- ical basis for oilfield development and adjustment.%油气储量是油气田勘探开发过程中的综合反映，储量计算结果的合理程度直接影响到油田勘探开发决策。基于高精度的三维储层地质模型进行储量计算，不但解决了传统容积法在进行复杂油气藏储量计算时储量参数难以取准的问题，同时能够更加准确地反映储量的分布范围。以新立一新北地区为例，在高精度三维地质模型基础上应用Petrel计算出的储量值客观合理，综合运用计算出的储量值与储量丰度值结合相关参数进行储量评价，为油田开发调整提供了地质依据。
