Using subterranean rock cores as samples, the impact of depletion exploitation and cyclic gas injection on occurrence dynamic utilization condensate oil damage to reservoirs were studied. Initially, internal pore structure core was analysed using computer tomography (CT), followed by experiments, with in-situ CT scanning samples. The results indicate that under different fracture apertures, exhibits wave flow slug states. production effectiveness is significantly superior production, saturation decreasing over 30%. During injection, fractures serve main channels, being extracted first. In most significant effect seen during first a decrease in around 3%. Subsequent injections show decreases approximately 1% 0.5% respectively. As volume increases, extent cumulative rate improvement also gradually increases; however, once reaches reservoir pressure, will decrease. These findings provide technical support for optimizing development mode reservoirs, clarifying seepage law gas, providing efficient fractured reservoirs.

During the cyclic injection and extraction process in underground storage wellbores, cement sheath undergoes loading unloading stress cycles. In this study, we investigated mechanical properties of latex-modified stone (LMCS), widely used oil gas wells, through uniaxial triaxial tests. The aim study was to determine effect various conditions on compressive strength stress–strain behavior LMCS. results show that curve LMCS exhibits a hysteresis loop phenomenon, with intervals decreasing throughout entire process. As number cycles increases, cumulative plastic strain increases approximately linearly. Under conditions, elastic modulus tends stabilize. However, under continuously as increases. This result provides data for engineering predictions. Furthermore, comparison shows its develops rapidly while is larger conditions. These findings provide valuable reference constructing wellbores.

Summary Condensate gas reservoirs in the middle and late stages of development are faced with problems such as formation pressure reduction, serious retrograde condensation, oil seepage channel plugging, which make it difficult to further improve recovery by conventional methods. For this kind condensate reservoir, paper we put forward air injection technology a means, taking K reservoir Tarim Oilfield research object. We explored thermal oxidation characteristics displacement efficiency oil/volatile through experiment. In addition, determined quantitatively minimum miscibility (MMP) samples at high temperature correlation between MMP high-temperature, high-pressure slimtube experiment, clarified mechanism “thermally assisted miscible” fine full-component numerical simulations under high-temperature conditions, indoor experiments could not achieve. The results showed that can form stable front injecting air, is more than 90%. flue produced reaction decreases gradually increase, only 11 MPa 260°C. formed heat release forces phase into phase, extraction makes C2-C4 increase continuously, both promote realization heat-assisted evaporation miscible phase. This thermal-assisted miscible-phase an innovative replacement for greatly improving stages.
