利用测试资料预测压裂后最低产量的一种方法

A Method of Prediction the Minimum Production after Fracturing from Test Data.

利用不稳定试井原理,结合地层测试已取得的地层参数进行分析,得出预测产能的公式。运用此公式求出预测产量,与压裂改造措施后取得的试产资料对比,预测结果与实际改造后试产所取得的结果吻合较好。此方法利用压裂后最低产能预测公式可指导压裂选层,判断是否有压裂价值,节约成本。

Based on the theory of transient well test, combining formation parameters analysis obtained from formation test, the formula of predicting productivity has been found. Comparing the result of the way with prediction test data after fracturing, it has been found that the two match each other very well. It proved that the method of predicting the minimum production after fracturing might can be used to direct picking formation about fractured, and estimate whether it is worth being fractured and reducing the cost.
