准噶尔盆地乌尔禾—夏子街地区不整合发育特征及其在油气成藏中的作用

准噶尔盆地乌尔禾夏子街地区二叠系至侏罗系发育多期不整合，包括削截及多期削截不整合、超覆不整合、褶曲不整合、断褶不整合和平行不整合。风化剥蚀程度的不均一性使不整合有3种典型岩石组合：底砾岩-风化壳-淋滤带型，主要分布在断裂带北部，呈条带状分布，底砾岩滞留原地，风化壳保存较好，淋滤带发育；水进砂体-风化壳（风化黏土）-淋滤带型，因湖侵导致的远物源搬运，砂层分选、磨圆度都很好；砂泥层-风化泥岩型或砂泥岩叠合型，是多次水进水退形成的。构造部位不同、构造变形强度不同、沉积物源不同是造成不整合结构差异的主要因素。在此基础上，分析了不整合成因模式。乌尔禾夏子街地区与不整合有关的油藏众多，主要有削截不整合、断褶不整合形成的不整合面遮挡油气藏和超覆不整合形成的地层超覆油气藏。图9表1参23     

准噶尔盆地东部侏罗系沉积相及沉积层序

通过对准噶尔盆地东部侏罗系的沉积环境和沉积相的研究,应用层序地层学方法对侏罗系进行了进一步划分与对比;应用地质、测井及地震等方法对该区的沉积相和沉积层序进行了综合分析.认为,本区侏罗系主要是一套受构造和气候条件控制的陆源碎屑沉积.按其沉积特征可分为潮湿型与干旱型两类;按低位体系域的特点又可分为北部缓坡型和南部陡坡型.     

Solvothermal synthesis and structure of a neutral layered borate B3O4(OH)(C4N2H10)0.5 containing helical chains

A new neutral layered borate B₃O₄(OH)(C₄N₂H₁₀)_0.5 (denoted BO-CJ 38) has been solvothermally synthesized. The piperazine molecules act as organic ligand and strcuture-directing agent. The left- and right-handed helical B–O–B chains are linked together via piperazine molecules to form infinite organic–inorganic hybrid layers. The aromatic piperazine molecules may play an important role in the formation of helical inorganic chains.

鲁奇加压气化含酚废水回收工艺的改进

传统的加压气化含酚废水回收工艺无法去除来料水中大量的氨,导致来料水的酸碱度偏高,使得含酚废水处理后仍无法达到生化系统处理的要求。通过对传统工艺的改进,含酚废水中CO2、NH3的脱除率大幅提高,降低了来料水中酸碱度,使含酚废水的回收达到了设计要求,保证了装置的运行和系统的稳定性,并带来了一定的经济效益。     

The optimal synthesis condition by sol–gel method and electrical properties of Mn1.5−xCo1.5NixO4 ceramics

A series of Mn_1.5−xCo_1.5Ni_xO₄ (0≤x≤1.2) negative temperature coefficient materials was synthesized by the sol–gel method. The optimal pH of reaction solutions was obtained by theoretical calculation. XRD and X-ray intensity ratios (I₂₂₀/I₄₄₀) and (I₄₄₀/I₄₂₂) studies showed that as-sintered ceramics are single spinel structures with different cation distributions. The Ni²⁺ ions not only enter B-site but also occupy A-site. Electrical studies showed that with increasing Ni content, the resistivity decreased from 909.229 Ω cm to 221.873 Ω cm initially in the range of x≤0.5 and then increased to 726.933 Ω cm when x=1.2, whereas the B value decreased from 4427 K to 2134 K. In addition, different sintering temperature ceramics were investigated. A higher sintering temperature results in lower resistivity and B value at same Ni content. The Mn_1.0Co_1.5Ni_0.5O₄ material showed much improved electrical stability at 125 °C for 1000 h. The rate of change (ΔR/R) is 0.2%.     

Estimation of Proppant Size Distribution Using Image Analysis

The determination of proppant settling velocity in fracturing fluids is of significant importance in fracturing design. In order to characterize proppant shape and surface roughness effect on its settling velocity, equivalent hydraulic diameter of proppant settling in 0.1% wt polyacrylamide solution was presented. According to the measured proppant geometric diameter using image analysis, the correlation between equivalent hydraulic diameter and geometric diameter has been established, and goodness of fit is perfect with average relative error of 4.21%. Comparison between proppant equivalent hydraulic diameter and its Stokes diameter falling in glycerol has been conducted, and the proppant Stokes diameter is larger than the geometric diameter. However, due to the shear-thinning property and low apparent viscosity of 0.1% wt polyacrylamide solution, the proppant equivalent hydraulic diameter is smaller than the geometric diameter.     

核电站指套管磨损缺陷的扫频涡流检测及创新型特征提取

为避免核电站指套管在微振磨蚀作用下产生磨损缺陷导致反应堆冷却剂泄漏,需要精确定量指套管磨损缺陷深度。建立了指套管涡流检测的有限元模型,通过仿真分析了指套管磨损缺陷的深度、轴向长度、周向角度对涡流检测信号的影响,结果表明涡流检测信号的相位角特征与缺陷深度不是独立相关的,使用常规单频涡流检测方法会导致缺陷深度误差过大。基于此提出了指套管磨损缺陷的扫频涡流检测方法,并从中提取了创新型特征,即过零频率特征。仿真分析结果表明过零频率特征与缺陷深度高度独立相关。
