简介：通过对尕斯库勒砂西区块N1—N21油藏Ⅺ、Ⅹ—Ⅸ、Ⅷ—Ⅵ、Ⅴ—Ⅰ油层组段沉积相特征、沉积体系展布及演化规律的综合分析,认为砂西区块N1—N21油藏从下向上发育滨浅湖亚相、辫状河三角洲前缘-滨浅湖亚相、辫状河三角洲平原-前缘亚相,整体为一套反旋回沉积.在此基础上分析了砂西区块N1—N21油藏沉积相与油气分布的关系.结果表明,分布于Ⅷ—Ⅵ油层组的辫状河三角洲分流河道及构造高部位的河口坝、远砂坝微相砂体为该地区的主要储集体,Ⅴ—Ⅰ油层组发育的泛滥平原微相泥岩为该区的区域性盖层.

简介：采用GM70手持式二氧化碳测试仪等测量仪器,对兴文石海洞乡天泉洞内CO2浓度进行测量。根据对天泉洞2008年7、8月CO2浓度的实测数据资料,从高程、洞道横断面大小、洞道深度、游客等影响因素对CO2浓度分布的影响进行分析,给出了洞内CO2的分布特征。研究发现:高程对CO2浓度影响较小;洞道越深、洞断面越小,CO2浓度越大;游客对溶洞内CO2浓度贡献很大;目前洞内CO2浓度还不足以威胁到游客的身体健康。得出的结论和实测数据为保护游客身体健康和洞穴旅游开发管理提供了科学依据。

简介：塔河油田2区三叠系油藏是西北分公司开发较早的碎屑岩油藏之一，开发层系有上油组、中油组，油柱高度在15～20m，储层为辫状三角洲相辫状三角洲前缘亚相水下分流河道、河口坝、分流间湾微相沉积，非均质性严重。本区上油组砂体厚度40～0m，中油组25～35m，分布较稳定，物性为中孔、中高渗储层，原油属低粘度轻质油。但2区三叠系油藏实钻变化大，见水快、产量递减快、含水上升快、采出程度低，开发效果较差，经过多次调整虽有一定程度改善，仍存在一些问题。本文认为2区三叠系油藏开发效果较差的原因之一是对本区油藏类型的认识上存在问题即2区三叠系油藏是以断裂控制的断块油藏而非背斜油藏，并延伸分析正在投入开发评价的S96-T901井区、TK232-T453井区及T206-T208井区等都为断块（断背斜）油藏。应用断块油藏的观点对塔河地区三叠系油藏勘探开发有重要指导意义。

简介：我国高分系列卫星数据因具有重访周期短、价格低廉、精度较高的特点,在矿山开发监测工作中得到了广泛的应用。本文在深入了解高分二号卫星数据特征的基础上,以甘肃永登县为例,利用机器学习模型中支持向量机算法(SupportVectorMachine,SVM)自动提取矿山开发信息,在处理的遥感影像上进行样本采集,借Matlab平台对样本及影像数据进行归一化、降维处理(PCA)。利用SVM模型进行信息自动提取过程中,选取径向基核函数(RBF),运用量子粒子群算法进行参数寻优,最终对提取结果进行野外调查。查证结果表明利用SVM模型进行矿山开发信息自动提取是可行的。该研究为国产数据在矿山监测应用中提供了新的思路。
