井壓測試分析中，一般將井壓下降及上升資料各別分析，比較少同時分析井壓下降及上升資料。本研究主要目的是建立井壓下降及上升資料整合分析之方法，包括理論推導的半對數作圖法之方程式，以及典型曲線分析法之建立，以發展更完整的井壓測試分析應用模式。
本研究先建立及驗證地層數值模式後，再繪製整合井壓下降及上升典型曲線。利用所建立之數值模式來模擬現場案例之壓力和流率資料，並利用模擬之壓力和流率資料作半對數圖和典型曲線分析。
本研究所獲得之主要結論為：（1）本研究推導出整合壓力下降及上升方程式和文獻中所提及的整合半對數圖分析方程式一致，並可用於整合壓力下降及上升半對數作圖分析中；（2）本研究發展整合壓力下降及上升典型曲線以及其分析之方法；（3）整合壓力下降及上升半對數作圖分析和典型曲線分析可成功分析定流率或變流率生產井的壓力下降及上升資料；（4）在變流率測試分析案例下，利用整合壓力下降及上升半對數作圖分析法，可達到相同方程式及直線作圖的整合分析，而其分析結果之準確度與傳統半對數作圖分析相當；（5）在變流率測試分析案例下，使用偽生產時間處理壓力上升資料並與整合壓力下降及上升典型曲線分析，相較於其它處理壓力上升資料方式，不論是在利用地表或井底流率資料來分析時，其分析之結果皆較準確；（6）將井壓下降和上升資料合併起來分析，可提供分析者在分析時更多的資訊，有助於分析時的判斷和分析效率的提升。

The general method in well-testing analysis is to separately analyze the pressure drawdown and buildup data; it is rare to combine the pressure drawdown and buildup data for analysis. We developed an improved and integrated method of analyzing pressure drawdown and buildup data; it includes a theoretically derived equation for semi-log plot analysis as well as type-curve analysis.
We first established and then confirmed a numerical model of a reservoir, before drawing the type-curves of integrated pressure drawdown and buildup. The numerical model was used to simulate field data that contained pressure and flow-rate data.
The conclusions from this study were that (1) the theoretically derived equation of integrated pressure drawdown and buildup, which is the same as the equation of the unified semi-log plot analysis in literatures, can be used for integrated semi-log plot analysis of pressure drawdown and buildup; (2) the type-curves of integrated pressure drawdown and buildup were developed and their applications were also described; (3) semi-log plot analysis and type-curves analysis of integrated pressure drawdown and buildup can be used when analyzing a constant or variable flow-rate well; (4) in a variable flow-rate well, the results’ accuracy of the integrated semi-log plot analysis correspond almost exactly to the results of traditional semi-log plot analysis; (5) in a variable flow-rate well, the results of a type-curve analysis of integrated pressure drawdown and buildup were more accurate than other methods, no matter what surface or sandface flow-rate data the analysis used; (6) integrating the pressure drawdown and buildup data provides more useful information in a pressure test analysis. The integrated method improved the interpretation and the efficiency of analysis.
