Tahe Vuggy Carbonate Reservoir Numerical Well Test Interpretation Methods Applied Research

This paper directs the slot and hole type carbonatite specific reservoir and reservoir geologic feature of tahe oilfield, and the main problems of current analysis well testing interpretation used in slot and hole type reservoir, unfold the finite element numerical well test application study. Introduce the numerical well test and reservoir model combination function into the study, realized the efficient description of the seep cell dynamic percolation model of slot and hole type carbonatite reservoir, such as "moniliform", "compound" and so on. And on the basis of the anciently 23 wells welltesting pressure curve and producing characteristic systems analysis, established 9 kinds well testing dynamic conceptual models of tahe Ordovician and homologous type curve plate, sole the well test dynamic description technique difficulty problems of dissymmetry complicated shape reservoir boundary, supply reliable technology buttress platform for the well test dynamic description and estimation of the intricacy reservoir.Apply the finite element numerical well test analysis technology into this study, put across the well test performance evaluation of one with multiple wellbore storage seep unitary, aslo the early stage performance evaluation and deliverability predictive analysis of one new developed area appraisal well. Especially the early stage reservoir performance description and forecast harvest of S112 well, it has some supervise sense to the next step reconnoiter or exploitation possess for this region.
