摘    要:油气田(藏)规模序列法是油气资源评价常用的方法之一,其优点是不但可以给出总的资源量,而且还可以给出各油气田(藏)的规模和序列,不足是其预测结果带有多解性。在多年的资评工作中,形成了一套求取规模序列中关键参数的科学方法:依据其他方法(成因法等)求取的资源量来约束规模序列法求取的地质资源量;依据高勘探区地质资源量与最大单一油气田(藏)规模统计关系来约束评价区最大单一油气田(藏)规模;根据预测单元可能存在的圈闭数(包含隐蔽圈闭)来限制预测的油气田(藏)个数。通过采用总量约束、最大单一规模约束和油气田(藏)个数约束,获得的结果克服了原方法存在的一些问题,使评价结果更科学,更符合地质实际。以该方法在黄河口凹陷等地区的应用实例证明了评价结果与勘探认识吻合较好。

关 键 词:油气资源评价  油气藏规模序列法  多参数约束法  黄河口凹陷

Abstract:The reservoir size sequential method is one of the commonly-used methods for petroleum resource estimation. It possesses the advantage of giving not only the total resources but also the scale and sequence of each reservoir,and the deficiency is the multiplicity of predicting results. A set of scientific methods for obtaining the key parameters of reservoir size sequential have been set up during years of work on hydrocarbon resource assessment, which including: a) using the resources that are computed by other methods (such as the genetic method) to constrain geological resources gained by reservoir size sequential method; b) using the statistical relationship between geological resources and the largest single reservoir size in mature exploration areas to constrain the largest single reservoir size in an assessed region; c) using the number of likely-existing traps(including subtle traps) to restrict the number of the predicted reservoirs. Through the use of total amount restraint, the largest single size restraint and reservoir number restraint, the assessment result overcomes problems that exist in the original method and accords better with geological conditions. The application cases of this method in Huanghekou Sag in Bohai Sea and other areas indicate that the prediction results are adapted relatively with exploration facts.
