The BZ 34-1 oilfield is a typical gas cap edge water reservoir in the Bohai oilfield. main characteristics of were multi-phase sand body stacking and was composed three parts: cap, oil reservoir, water. actual production site results show that permeability difference multi-layer bodies has serious impact on development effect. This article establishes model numerical based total recovery degree...

for this study, asmari (oligo-miocene) and bangestan (cretaceous) reservoir oils from themarun oilfield were studied geochemically. gas chromatograms and stable isotopes of carbon and sulfur indifferent oil fractions were studied. normal alkanes nc15+ are as high as 93% with a saturate percentage up to53.9% which reveal a high maturity of asmari and bangestan reservoir paraffinic oils. carbon p...

accurate permeability estimation has always been a concern in determining flow units, assigning appropriate capillary pressure andrelative permeability curves to reservoir rock types, geological modeling, and dynamic simulation.acoustic method can be used as analternative and effective tool for permeability determination. in this study, a four-step approach is proposed for permeability estimati...

This paper, by conducting comprehensive analysis on water-flooding reservoir, intensively studied and discussed the characteristics of geological development, determined evaluation indexes development effect, carried out research from five steps, first is introduction part, it conducted indepth study discussion background, significance, literature review, methods four aspects. The second outlin...

Gas-liquid separator is an important surface equipment in oilfield development. Improving the separation efficiency of great significance to overall economic benefit oilfield. Spiral a high device that has been widely used, but at present, there are not enough studies on number spiral turns and pitches. In view this problem, paper analyzed gas–liquid separators with different pitches via fluent...
