海拉尔盆地贝中次凹断裂发育特征及其对油气的控制作用

在系统研究贝中次凹断裂的发育及形成演化特征的基础上,分析了断裂对贝中次凹油气成藏条件的控制作用。贝中次凹自下而上划分为断陷构造层、断-坳转化构造层和凹陷构造层。根据断裂与各构造层的切割关系及运动学特征,以T22为界将贝中次凹发育的断裂划分为上、下两个断裂系统,进一步划分为早期伸展断裂、中期张扭断裂、早期伸展中期张扭断裂和长期活动断裂4种断裂类型。各个历史演化时期控制着不同成因的断裂发育,在上部断裂系统中发育了由于泥岩密度反转作用所形成的非构造成因的断裂密集带,断裂的形成和演化影响主力烃源岩的分布和热演化程度,形成多种类型的圈闭,为油气运移提供良好地运移通道。长期继承性活动断裂与上部断层系构成的密集带是油气运聚成藏的有利指向区。     

滴南凸起-阜北斜坡中上侏罗统-下白垩统油气成藏条件分析

作为准噶尔盆地腹部较早开发的地区之一,近年来在滴南凸起下白垩统及白家海凸起-阜北斜坡区的中上侏罗统地层内相继发现了高产油气藏,揭示了该区中上侏罗统-下白垩统具有良好的生、储、盖成藏条件,丰富的圈闭类型和有效的疏导体系。在成藏条件上,东道海子凹陷、阜康凹陷的石炭统、二叠系平地泉组以及侏罗系的八道湾组、三工河组、西山窑组等多套烃源岩为侏罗-白垩系成藏提供了充足的油气,河流、三角洲沉积体系控制下的中上侏罗统头屯河组、齐古组以及下白垩统的清水河组、呼图壁河组分布有多套有效的储盖组合,长期继承性的断裂系统及砂体和不整合面作为油气的疏导体系,在成藏条件分析的基础上总结了滴南凸起-阜北斜坡地区3种油气成藏模式。     

Surface characterization of polyimide and polyethylene terephthalate membranes toward plasma and UV treatments

This study is to bring an overview on various methods regarding the surface treatment performed on different polymeric membranes in relation to a deference between the treatment mechanism and their chemical structure. Herein, plasma and UV surface treatments (PST and UST) were utilized to treat the surfaces of two commercial membranes, i.e., aromatic polyimide and polyethylene terephthalate for various durations using a discharge electrode and an UV LED curing system, respectively. Based on the effects of PST and UST processes on the surface of these membranes, their surface properties have been characterized to surface morphology and hydrophilicity (or wettability), at same time the changes have probably occurred on their surface during the PST and UST processes. As a result, their hydrophilic behavior was significantly enhanced after conducting these treatment processes based on the investigation of water contact angle. Moreover, Fourier-transform infrared and Raman spectroscopy manifested the changes in the chemical bonds, interactions and orientations of molecules, which confirmed the apparition and insertion of polar functional groups after the surface treatments, and accordingly, their wettability was enhanced significantly. Also, optical microscopy images showed direct impactions on their surface and the evidence of slight surface aging/damage during the treatment processes based on the presentation of the strange streaks on the treated surfaces. In particular, the peel forces exhibited an increase comparing to the initial membranes, which is characteristically for enhancing their adhesion behavior. Hence, these results are needful for improving the surface properties of a material, and obtaining better adhesion behavior on the membrane-like materials and recycling polymer materials.
