Based on a large amount of core analysis data in eastern Pre-Caspian Basin, the relationship between permeability and porosity its influencing factors are studied. The sedimentary environments Carboniferous System Basin include open platform, restricted platform evaporate platform. For dolomite reservoirs there three main combination patterns pores, namely, inter-crystalline solution micro-pores, intra-crystalline among which first highest permeability. limestone reservoirs, pores...
Carboniferous carbonate reservoirs at the eastern edge of Pre-Caspian Basin have undergone complex sedimentation, diagenesis and tectonism processes, developed various reservoir space types pores, cavities fractures with complicated combination patterns which create intricate pore-throats structure. The pore-throat structure leads to porosity-permeability relationship, bringing great challenges for classification evaluation efficient development. Based on comprehensive analysis cores, thin...
The productivity prediction of weakly volatile fractured reservoirs is influenced by reservoir parameters and fluid characteristics. To address the computational challenges posed complex fractures, an equivalent fracture element method proposed to calculate permeability in zones. A three-phase seepage model based on material balance developed, using Baker linear determine relative permeabilities oil, gas, water while accounting for bound saturation. Dynamic drainage distance conductivity...
According to the characteristics of overpressure carbonate reservoirs Kenkiyak pre-salt oil field in littoral Caspian Basin, cores were made artificially and stress sensibility matrix with non-packed, semi-packed fully packed fractures analyzed. The method gas measurement was used experiment. confining pressure sample first increased then decreased. When became stable, porosity permeability data from each point obtained analyze cores. results showed that these four types a descending order...
Taking the Kumkol South oilfield in Turgay Basin, Kazakstan as an example, this article summarizes controlling pattern of different types sandstone architecture on remaining oil distribution through examining characteristics, development effect and characteristics meandering river sandstone, braided delta sandstone. The has simple which is extensive connecting body with horizontal mud-interlayers. water flooding sweeps evenly edge-bottom drives quickly braid And vertical blocking controlled...
After complex geological transformation, such as sedimentation, diagenesis, and tectonic carbonate reservoirs have developed multiple reservoir spaces with significant heterogeneity various pore-throat structures, including pores, vugs, fractures. Due to these characteristics, many problems been caused during the development of reservoirs, large differences between initial production capacities single wells serious water channeling after injection, which brought challenges efficient...
The vacancy formation thermodynamics in six FCC metals Ag, Au, Cu, Ni, Pd and Pt are determined from atomistic simulations as a function of temperature. investigation is performed using the embedded atom method interatomic potentials finite temperature properties within local harmonic quasiharmonic frameworks. dependence free energy, entropy, enthalpy volume determined. authors find that energy can make significant contribution to concentration at high temperatures. An additional goal study...
Taking the Kumkol oilfield of high water cut in South Turgay Basin, Kazakstan as an example, this article built architecture models meandering river sandstones, braided sandstones and delta analyzed influence superimposed structure characteristics between different types internal features on warterflooding mechanisms effects. The are mainly characterized by lateral accretion shale beddings inside, with simple overlay-relationship sand bodies. In injected almost sweeps through bottom bodies...
The carboniferous carbonate reservoirs in the North Truva Oilfield have undergone complex sedimentation, diagenesis and tectonic transformation. Various reservoir spaces of pores, caves fractures, with strong heterogeneity diverse pore structures, been developed. As a result, quantitative description structure is difficult, accuracy logging identification prediction low. These pose lot challenges to classification evaluation as well efficient development reservoirs. This study based on...
By core observation and slice analysis, two types of fractures can be identified in reservoirs Zanarol Oilfield, including macro-fractures micro-fractures. Macro-fractures refer to tectonic stylolites, micro-fractures mainly grain breakage micro-tectonic fractures. The development the different scale is controlled by lithology, formation texture stress field. are well developed tight rocks such as micrite granular carbonate good porosity permeability. Oilfield a typical layered pool, with...
The concept model of ancient buried hill karst reservoirs was built taking the NWKK carbonate rock oilfield in South Turgay Basin Kazakhstan as an example, and characteristics their controls on productivity were analyzed vertical horizontal directions. Vertically, can be subdivided into, from top to bottom, weathering crust zone, epikarst caves vadose zone phreatic which development fractures is strengthened gradually; Six reservoir types, breccia pore, cave, vug, fracture-vug, fracture-pore...
Taking the Kenjiyak Oilfield in Kazakhstan as an example, fracture characteristics and genetic mechanism of carbonate reservoirs with overpressure were discussed. The study showed that are formed under developed hydraulic fractures besides tectonic karstic fractures. Carboniferous sub-salt Kenkiyak mainly Mesozoic Cenozoic, on a macroscopic level they cut rocks into brecciated texture or packed by calcite veins, microscopic radiant distribution around pores. formation evolution system region...
A fracture-pore carbonate reservoir in eastern Pre-Caspian basin was taken as an example to analyze the oil phase behavior change and seepage physical characteristics of weakly volatile reservoirs with decrease formation pressure. Based on analysis, water-flooding development technique policy under different pressure presented. Experiments show that crude degasifies decreases, methane intermediate hydrocarbons separated out successively, gradually transforms into ordinary black oil. With...
