实现乙烯气体(C_(2)H_(4))实时在线精确检测对石油化工、煤矿等行业安全具有重要意义,但是C_(2)H_(4)在近红外波段的谱线强度信息不明确,具有谱带吸收特征,且与CH4有明显的混叠干扰,因此对其浓度进行精确检测是目前激光吸收光谱测量面临的共性技术难题。将波长调制光谱中的标定方法与直接吸收光谱相结合,提出了一种适用于C_(2)H_(4)气体检测的标定直接吸收光谱法(CDAS)。该方法不需要激光吸收光谱反演过程中的确切谱线强度信息,并克服了波长调制光谱在测量过程中出现的非线性效应。为了避免特定工况(如煤矿)中CH_(4)的干扰,实验装置采用了高精度压强控制系统,并且在100 mbar(1 bar=105 Pa)稳定压强下实现了CH_(4)和C_(2)H_(4)混叠光谱的分离。实验过程中对1626 nm附近的CH_(4)和C_(2)H_(4)仿真和实测吸收光谱进行了分析,确定了C2H4的标定光谱范围,进而验证了该方法在体积分数低于100×10^(-6)的范围内,对C2H4气体的检测误差不超过-1.47×10^(-6),并且测量体积分数与标准体积分数之间的线性拟合优度达到了0.999。对体积分数为10×10^(-6)的C2H4直接吸收光谱进行分析,以1倍信噪比对应的浓度作为检测下限进行等效计算,得到检测下限为1.38×10^(-6)。在Allan方差分析中,积分时间为77 s时检测精度达到了0.04×10^(-6)。以上实验结果充分说明了标定直接吸收光谱法能够在近红外波段实现C2H4的精确检测,并为此类气体的检测提供了一种新思路。

针对石油化工、煤矿安全等领域对气体浓度宽量程检测的需求,对波长调制光谱检测气体浓度时的非线性特征进行了研究,提出仅用波长调制方法实现气体浓度的宽动态范围测量。该方法根据激光吸收光谱技术原理,对吸收项及其泰勒展开式进行分析,在小吸收度时采用线性近似,在大吸收度时采用三次多项式近似。并且使用甲烷气体(CH_(4))作为实验对象,搭建了CH_(4)检测系统,验证了该方法在气体浓度宽量程检测方面的可行性。经过实验验证,该方法能够实现4个数量级大跨度范围(1.5×10^(-6)~10000×10^(-6))的CH_(4)检测。对阈值为1000×10^(-6)(在3 m有效光程下吸收度为0.0236)以下和以上的气体体积分数分别进行检测,反演浓度和标准浓度之间均表现出良好的相关性,拟合优度均大于0.999。另外,在吸收度大于0.0236的范围内,该方法的最大测量相对误差为0.93%,绝对误差为-92.1×10^(-6)。为了验证其稳定性,对体积分数为5000×10^(-6)(吸收度为0.118)的CH_(4)进行长时间测量,并统计其反演浓度的高斯分布,经过计算得到其半峰半宽为15.9×10^(-6)。实验证明该方法突破了传统波长调制光谱只能测量低浓度的局限,在宽量程检测中获得了良好的检测结果,为气体浓度宽量程检测提供了一种新思路,同时也大大拓宽了波长调制光谱的应用范围。

为探究准噶尔盆地玛湖凹陷南缘风城组碱湖沉积环境下的成岩作用特征及对储层的影响机制,明确优势成岩相的分布,在岩石学特征、孔隙类型、成岩作用以及成岩环境演变分析的基础上,定量表征了压实、胶结和溶蚀对储层改造强度,建立了成岩相划分方案,并基于单井取心层段的评价结果刻画了成岩相分布特征,阐释了成岩相分布影响机制。研究表明:研究区风城组储集空间呈现“基质孔隙为主、微裂缝为辅”的双重介质特征,其中粒内/粒间溶孔在基质孔隙中占主导地位。风城组历经碱性沉积环境和碱性—酸性—碱性的成岩环境演变,碱性沉积环境和早期碱性成岩阶段是粒间孔胶结损耗和火山物质水解以及斜长石钠长石化形成溶蚀孔的重要时期,建设性和破坏性成岩作用并存;中期成岩酸性环境下的扩孔作用使得溶蚀孔成为主要储集空间,致密化程度有所缓解;晚期碱性成岩环境下伴随着碱性矿物离子浓度再次增加,并开始在剩余粒间孔、溶蚀孔等储集空间内沉淀,储层致密化程度进一步提升。平面上,扇三角洲平原和前缘交界处胶结和溶蚀作用发育程度较弱,多发育压实相,平均孔隙度约为4.9%;扇三角洲内前缘至外前缘交界处溶蚀作用强于胶结,以胶结—溶蚀相为主,平均孔隙度约为6.6%,中部和南部断裂附近为溶蚀相,平均孔隙度高达9%;扇三角洲外前缘多发育溶蚀—胶结相,储层平均孔隙度约为3.1%。碱湖沉积背景下的碱性成岩作用对储层改造具有两面性,在酸性/碱性溶蚀控制下的胶结—溶蚀相和溶蚀相是该地区致密油聚集的有利场所,也是该地区单井高产的关键因素。

Lacustrine shale from the Qingshankou Formatin of Songliao basin and the Shahejie Formation of Bohai Bay basin, and marine shale from the lower Cambrian Jinmenchong Formation of Qiannan depression were analysed by using rock pyrolysis, TOC （total organic carbon）, XRD （X-ray diffraction）, SEM （scanning electron microscope）, FE-SEM （field emission scanning electron microscope）, high pressure mercury intrusion, and low pressure N2 and CO2 gas adsorption experiments, in aim to reveal their reservoir features. The results show that：（1） the width of micro-pores of all the studied samples mainly ranges from 0.45 to 0.7 nm indicated by CO2 isotherms, and the width of meso-pores is less than 10 nm, with type IV adsorption isotherms and type H2 hysteresis loop, indicative of ＂ink-bottle＂-shaped pores. Good correlations exist among pore volume, surface area and averaged pore diameter, and a good positive correlation exists between micro-pore volume and TOC content; however, there is no obvious correlation between meso-pore volume and TOC content; （2） interparticle pores, pores among the edge of mineral grains and organic matter pores were all identified in marine and lacustrine shale, among which the interparticle pores may be influence by dissolution effect. Not all bitumen develops organic matter pore, and only high to over mature bitumen present pores. Now the description methods of micrometer scale pores developed in shale are very lack. Micro- fractures developed in Jiyang depression and dissolution interparticle pores developed in Songliao Basin should be the accumulation sites for shale oil in lacustrine shale, and can be as sweet spots.

The tight reservoirs of the Fengcheng Formation at the southern margin of the Mahu Sag have strong heterogeneity due to the diversity in their pore types, sizes, and structures. The microscopic characteristics of tight reservoirs and the mechanisms that generate them are of significance in identifying the distribution of high-quality reservoirs and in improving the prediction accuracy of sweet spots in tight oil reservoirs. In this paper, high-pressure mercury intrusion (HPMI) and nuclear magnetic resonance (NMR) experiments were carried out on samples from the tight reservoirs in the study area. These experimental results were combined with cluster analysis, fractal theory, and microscopic observations to qualitatively and quantitatively evaluate pore types, sizes, and structures. A classification scheme was established that divides the reservoir into four types, based on the microstructure characteristics of samples, and the genetic mechanisms that aided the development of reservoir microstructure were analyzed. The results show that the lower limit for the tight reservoir in the Fengcheng Formation is Φ of 3.5% and K of 0.03 mD. The pore throat size and distribution span gradually decrease from Type I, through Type II and Type III reservoirs to non-reservoirs, and the pore type also evolves from dominantly intergranular pores to intercrystalline pores. The structural trend shows a decrease in the ball-stick pore-throat system and an increase in the branch-like pore-throat system. The dual effects of sedimentation and diagenesis shape the microscopic characteristics of pores and throats. The sorting, roundness, and particle size of the original sediments determine the original physical properties of the reservoir. The diagenetic environment of ‘two alkalinity stages and one acidity stage’ influenced the evolution of pore type and size. Although the cementation of authigenic minerals in the early alkaline environment adversely affected reservoir properties, it also
