Tight gas is a clean and low-carbon energy with great development potential. However, in the middle late stages of tight reservoirs, there are characteristics low pressure, production high water cut. At present, few studies on dynamic supply boundary considering threshold pressure gradient, reservoir fracture stress sensitivity slip effect for gas-water two-phase model reservoirs. In order to improve assessment capacity features wells at new coupling was established this paper taken into...
Traditional seismic inversion has the problems of low lateral resolution and poor anti-noise performance. To address these challenges, advantages methods in time frequency domains are combined; Lp norm that can preserve more sparsity information is introduced into inversion. Meanwhile, multi-trace simultaneous become mainstream methods, which effectively improve quality pre-stack However, traditional have high computational costs difficult to obtain 3D result. Ensuring spatial continuity...
In this paper, a systematic technology is developed to study the influence of pore-throat structure and fracture development on water invasion behavior fractured gas reservoirs, quantitatively characterize law invasion, then formulate reasonable working system.In experiment, nuclear magnetic resonance ( NMR ) high-pressure mercury injection HPMI were used pore core samples, distribution invaded phase in throat was clarified.The effect permeability obtained by displacement test.Based existing...
<title>Abstract</title> It is a clean, low-carbon energy source for tight gas that has gained popularity in the sector its ability to significantly cut greenhouse emissions. On other hand, low formation pressure, well production, and high water saturation are features of reservoirs have been developed produced over an extended period time. In order improve assessment supply boundary production capacity wells at new coupling model gas-water two-phase was established this paper threshold...
Acoustic impedance (AI) inversion is widely used in geophysics and reservoir prediction. But the traditional method cannot fully exploit sparse characteristics of geological attributes. There are problems with multiplicity low resolution. To solve this problem, a data-driven acoustic reweighted L1 norm constraints (DRL1) proposed. In process, local cross-correlation analysis introduced to above problems. The as constraint (RL1) replace which constrained by norm. RL1 can describe more...
