应用地震资料计算锦州9-3油田储层储量的方法

Calculation of the Reserve of Jinzhou 93 Oil Field by Means of Seismic Data

以往油藏地质人员计算储层的储量，对于储层的物性参数不仅利用井中资料，井间资料只有通过井内插得到，没有很好地把地震资料利用起来，在制图及计算中花费大量时间．鉴于此种情况，通过人机联作绘制了一系列复合参数交会图，经多元统计分析后建立地震参数与储层参数间的数学关系．从而利用地震资料将井孔附近的储层参数扩展到整个油田，并提出计算储层储量的方法．

In fact, the reservoir parameters used in reserve calculation are only the parameters within well bores. The interwell reservoir parameters are obtained from the wellbore parameters by interpolation calculation. The method of reserve calculation does not make full use of seismic data. A lot of time and energy is taken in plotting and calculating. In view of the abovementioned facts, a new method of reserve calculation is put forward. First according to seismic data, a series of multiparameter crossplots are drawn by manmachine interaction,then by multivariate statistical analysis, a mathematical relational expression is established between reservoir parameters and seismic data. Lastly, the reserve can be calculated. The method of reserve calculation is given in the paper.Subject headings
