Comprehensive screening for functional substances from natural resources is always a hot research topic. Eicosapentaenoic acid- (EPA) and docosahexaenoic acid (DHA)-structured phospholipids (PLEPA/DHA) have versatile cardiovascular benefits as well superior bioavailability. Herein, the abundance of PLEPA/DHA in 16 aquatic products was specifically selectively screened using recently developed precursor ion scan-driven hydrophilic interaction chromatography–mass spectrometry (PreIS-HILIC/MS)...
In the Tarim Basin, various irregular fractured-vuggy reservoirs have developed along with main faults. These are geologically defined as carbonate fault karst. past few years, seismic attributes been widely used for identification and evaluation of However, there has less reliability analysis regarding their usage. Imaging using theoretical fault-karst velocity model can reflect shapes distributions fractures vugs, whereas imaging background simulate data in real cases. We adopted an...
The Cambrian superdeep dolomite in Tarim Basin has great resource potentiality. However, the reservoirs have seismogeological characteristics of deep burial, low porosity and permeability, complex fracture networks signal-to-noise, which cannot support efficient exploration development reservoir due to restricting precision prediction. fractures pores compose main storage spaces reservoir. To better characterize superior with fracture, we first describe properties using core data,...
Abstract Natural fractures are usually multiscale in size, orientations and distribution, resulting complex anisotropic characteristics. Analytical methods for quantifying the associated effective elastic properties based on some assumptions, such as dilute fracture concentration regular-shaped fractures, which do not occur actual reservoirs. Here, we conduct finite-element modeling of fractured rocks using least-square fitting method. The algorithm is developed a 3D case validated by...
The fault-karst reservoir, which evolved from the deformation and karstification of carbonate rock, is one most important reservoir types in Western China. Along deep-seated fault zones, there are a lot widely spread densely distributed fractures vugs. energy diffractions generated by heterogeneous structures, such as faults, fractures, vugs, much weaker than that reflections produced continuous formation interface. When using conventional full-wavefield imaging method, results layers...
The KS area with very complex near surface conditions and high steep structure of subsurface thrust nappes in the Kuqa Depression has a classical double (DCS). average porosity permeability target sandstone reservoir are about 4.5% 0.05 mD, which belongs to low deep-buried gas reservoirs. Lots seismic attributes often used support faults detection. However, most these methods difficult predict small-scale cracks or get poor results due limit structure. is compressed by north geological...
Synchronous prestack inversion technology has been widely used to predict the fluid and lithological properties of reservoirs. Its prediction accuracy depends on seismic data quality. Ultra-deep carbonate reservoirs in Shunbei area Tarim Basin were as research objects. Based shear wave (S-wave) method, petrophysical logging analysis was carried out select physical property-sensitive elastic parameters. A property indicator with porosity target curve constructed quantitatively characterize...
Abstract The current research aims to unlock the temporal and spatial distribution of sand‐bodies their relationship with hydrocarbon accumulation in mid‐deep layer basin margins, located eastern part Liuzan area Nanpu Sag, Bohai Bay Basin, China. Through this study, main target interval was divided into two fourth‐order sequences. lean sand mixed sedimentary belt great importance controlling identified through comprehensive use 3D seismic data, logging lithological data inversion data. A...
The size, distribution, and orientation of fractures are generally multiscale multi-dimensional in nature, leading to complex anisotropic characteristics. Theoretical or semi-analytical methods determine the effective elastic properties depend on several assumptions, including absence stress interaction idealized fractures. On basis finite-element models, we conduct numerical oscillatory relaxation tests for determining fractured rocks. approach calculating equivalent stiffness tensors...
Abstract Superdeep fault-karst carbonate reservoirs discovered over 7 km deep are controlled by strike-slip fault zones and karst collapses in Tarim Basin, Northwest China. The resulting fracture-cave system provides favorable migration channels reservoir spaces for hydrocarbon, while the characterization of internal structures remains enigmatic. Based on seismic imaging data, we conducted an integrated study damage curvature attributes, velocity anisotropies, attenuations. results show that...
Summary In order to get fine structure identification and have more accurate structural features or fracture location in shale-gas seismic imaging. We use the Kirchhoff pre-stack time migration processing VTI media depending on data of Sichuan Changning exploration work area. designed a new anisotropic flow, which could effectively eliminate influence anisotropy improve imaging accuracy. Then we found that using can make clearer relationship between horizons giving as well, especially give...
Real fractures are usually multiscale in orientations, sizes, and distributions, resulting complex anisotropic characteristics. Analytical methods for effective elastic properties based on some assumptions, such as dilute fracture concentration regular-shaped fractures, which do not occur actual reservoirs. Here, finite-element modeling of is conducted fractured rocks by a least-squares fitting procedure. The algorithm extended to 3D cases validated classical medium theories models with...
