综合分形预测和克里格估值的优点，提出一种研究储集层井间规模非均质性的ＦＩＦＫ方法，即正演井间分形克里格方法（ＦｏｒｗａｒｄＩｎｔｅｒｗｅｌＦｒａｃｔａｌＫｒｉｇｉｎｇ）。该方法的理论基础是分数布朗运动和地质统计学；在２口井间插值时用重新采样方法（三次采样）井行加密插值，既解决方法所要求的２口井数据点个数必须相等而实际往往不等的问题，又保证采样后曲线不变形；在形成数据体或图形时，根据２口井所处构造位置，采用相应地质概念模型处理数据，再进行分形预测，形成井间参数分布场；最后将分形预测结果变换为考虑构造位置的原始预测结果。用该方法预测东濮凹陷胡状集油田胡十二块的井间储集层非均质性，预测结果与示踪剂测试结果相当吻合，验证了该方法的实用性和预测结果的可信性。图４表１参２（邹冬平摘）
Based on the advantages of fractal prediction and Kriging estimation, a FIFK method for studying the cross-well heterogeneity between reservoirs is proposed, namely Forward Interract Fractal Kriging. The theoretical basis of this method is fractional Brownian motion and geostatistics. When interpolating between two wells, we use the resampling method (three times sampling) to perform the encrypted interpolation. The number of data points required by both methods must be equal The actual and often unequal problems, but also to ensure that the sample curve does not distort; in the formation of the data body or graphics, according to the location of the two wells where the corresponding geological concept model to process the data, and then fractal prediction to form the crosswell parameter distribution Finally, the fractal prediction result is transformed into the original prediction result considering the structure location. This method is used to predict the cross-well reservoir heterogeneity in Hu-12 Block, Huzhuangji Oilfield, Dongpu Depression. The prediction results are in good agreement with the tracer test results, which verify the practicability and predictability of the method Sex. Figure 4 Table 1 Reference 2 (Zou Dongping pick)
