Hylogger core scanning system is used to detailed scan shale gas drilling cores, obtaining visible-near infrared (spectral range 380nm-1100nm),short-wave 1100nm-2500nm) spectral curves and high-definition images. Taking Well weican 1 in the West Taikang Uplift South China North Basin as an example, based on analysis of clay mineral types target layer, it judged be alkaline deposit environment r...

Plunger dewatering gas extraction is a technology primarily used for low-yield natural collection. To maximize the efficiency of plunger extraction, optimization design necessary. This study based on principles lifting extraction. By calculating distribution fluid and pressure in wellbore during plunger's upward movement at startup, as it reaches wellhead, well shut-in, interconversion relation...

Abstract It is very important to accurately predict the gas well productivity and reasonably allocate production at early development stage of reservoirs. However, both non-Darcy stress sensitivity effects have not been investigated in dual-porosity model tight carbonate This paper proposed a new binomial deliverability single-well proration numerical model, which consider sensitivity. The fiel...
