Spontaneous imbibition is an effective method of tight sandstone reservoirs development. However, their underlying mechanisms are still unclear due to the representative issue caused by strong heterogeneity and complex oil-brine properties. In this research, physical properties thin-section images were systematically analyzed, spontaneous efficiency was examined from core tests. The results show that quartz feldspar predominantly contribute mineralogy. Low brine salinity, high oil viscosity,...
It is generally believed that conventional hydrocarbon accumulates in sandstone traps after migrating at a certain distance. Unconventional only migrates short distance before accumulation or being imbibed the tiny pores of shale and tight reservoir, there no obvious trap boundary. There are also different views on time interval between migration. In this paper, microscale simulation experiments used to study process oil during single pore-throat model, can 100% saturate pore migration with...
The Linxing area within the Ordos Basin exhibits pronounced reservoir heterogeneity and intricate micro-pore structures, rendering it susceptible to water-blocking damage during imbibition extraction. This study delved into traits of tight sandstone reservoirs in 8th member Shihezi Formation (also referred as He 8 Member) area, well their effects on fracturing fluid imbibition. Utilizing experimental techniques such nuclear magnetic resonance (NMR), high-pressure mercury intrusion (HPMI),...
Tight sandstone reservoirs have the characteristics of poor physical properties, fine pore throats, and strong microheterogeneity compared with conventional reservoirs, which results in complicated movable fluid occurrence laws difficult mining. Taking tight gas reservoir He 8 formation Sulige field as an example, based on property test analysis, constant velocity mercury injection, nuclear magnetic resonance experiments, optimized gray correlation calculation model is established by...
This study aims at investigating the applicability of commonly used water saturation test methods such as distillation extraction method, nuclear magnetic resonance (NMR) constant weight and Coulomb method in tight sandstone gas reservoirs. The above were studied optimized to overcome difficulties low content determination caused by porosity, permeability, small pore throat, high capillary force, bound sandstone, obtain relatively accurate data. results showed that data determined consistent...
This paper examines the damage caused by slickwater fracturing fluid to microscopic pore structure of tight sandstone in Chang 7 member Ordos Basin. A submicron CT situ displacement system was used analyze and graphically represent changes pores core samples following damage. The results show following: (1) fractures mainly occurs early stage incursion. is characterized a decrease effective volume, increase number pores, insignificant subsequent main causes are retention liquid phase...
The complex pore structure of low‐permeability sandstone reservoir makes it difficult to characterize the heterogeneity throat. Taking Sanjianfang formation in QL oilfield as an example, fractal dimension different storage spaces is calculated by using theory based on casting thin section, scanning electron microscope, and high‐pressure mercury injection, correlation between porosity, permeability, contribution space permeabilities analyzed. results show that mainly develops small pores,...
Based on the background of sedimentary characteristics, a large amount core and thin section analysis, taking Chang 6 reservoir Yanchang Formation in central western Ordos Basin as an example, through application scanning electron microscopy, high-pressure mercury injection, nuclear magnetic resonance microscopic water drive oil model, other experimental test methods, diagenetic facies types pore structure characteristics tight sandstone reservoirs are discussed analyzed depth. The results...
The main exploring technology of No.7 Yanchang Formation the Triassic reservoir in Ordos Basin adopts quasi-natural downhole energy driven by volume fracturing, and region production thus cannot be improved an injection well network. Enhanced oil recovery (EOR) has been carried out through enhanced imbibition process during stimulation work. To further understand oil-water displacement mechanism, a thin-cut chips shale experimental study was out. Simultaneously, nuclear magnetic resonance...
Abstract The copper dispersion‐strengthened matrix composites (Cu/CSiC) were fabricated on the stainless steel by using magnetron sputtering and ion‐beam mixing. pre‐deposition of Cu element is used to modify interface structure, hence, develop compatibility between Fe substrate C‐SiC coating. results show that layer can effectively broaden transition layer, where elements coating could be completely mixed with substrate. following heat treatment it further i.e. provide more Copyright ©...
