Well Testing | Year: 2017

X well is an inclined well, locating in Western Sichuan basin slope developed a series of lithological traps. Through analysis of geological structure and physical properties of reservoir around X well, it indicates that structural main parts nearly North-South axis, has three main fault near the well, X well is drilled from top to bottom of Maokou and Qixia two large formation, and among them of the Maokou has multiple reservoirs in vertical direction. Based on well test data, well test analysis is done combined with multiple sets of reservoirs, and according to inclined well structure, an oblique thickness value is taken as effective thickness, and the vertical well test model is selected instead of the horizontal one to conduct simulation and picture fitting, resulting in permeability, storativity ratio ω, other reservoir physical parameters and fault distance boundary condition. The conclusion is that, in condition of similar physical properties around different reservoirs, only one pressure and temperature system and depth difference is very small, it is feasible to put multiple layers together for well testing analysis and results are reliable. For test interpretation of slant well, vertical well model and oblique thickness value can be used instead of horizontal well model and vertical thickness value of gas well. Vertical well model needs fewer parameters and has better stability and reliability of operation. © 2017, The Editorial Department of Well Testing. All right reserved.
