摘要：MX井是明格布拉克构造上的一口“五高”深井,为保证试油测试安全实施,依据该井地质工程特征,优选试油方案,采用射孔测试联作技术、“两关一开”工作制度和“三阀一封”管柱结构。试油测试过程中,按设计要求控制油压和套压,防止油管和封隔器窜漏;起管柱前,压稳井,保证井控安全;按照防硫气体要求做好设备选择、安装和调试的工作,并依据探测H2S含量做出合理的相应措施以保证含硫井试油的安全;现场需要判断盐结晶,一旦确定发生盐结晶,立即循环压井以防盐堵。MX井7个层段试油结果最高地层压力111.57 MPa,最高地层温度163.41℃,最大日产油量22.67 m^3,最高日气产量18.43×10^4m^3,最高日产水量393.7 m^3,最高H2S含量44%,盐水Cl-最高为21.50×10^4mg/L,获得油气水样品和相关压力资料,实现高温高压安全试油测试作业,达到了试油目的。该工艺在高含H2S和高含盐的“五高”深井中实现技术突破,为“五高”深井试油测试提供了技术借鉴。

摘要：Amidst the development of photoelectrochemical(PEC)CO_(2) conversion toward practical application,the production of high-value chemicals beyond C1 compounds under mild conditions is greatly desired yet ***,through rational PEC device design by combining Au-loaded and N-doped TiO_(2) plate nanoarray photoanode with Zn-doped Cu_(2)O dark cathode,efficient conversion of CO_(2) to CH3COOH has been achieved with an outstanding Faradaic efficiency up to 58.1%(91.5%carbon selectivity)at 0.5 V ***/*** programmed desorption and in situ Raman spectra reveal that the Zn-dopant in Cu_(2)O plays multiple roles in selective catalytic CO_(2) conversion,including local electronic structure manipulation and active site modification,which together promote the formation of intermediate*CH2/*CH3 for C-C *** from that,it is also unveiled that the sufficient electron density provided by the Au-loaded and N-doped TiO_(2) plate nanoarray photoanode plays an equally important role by initiating multi-electron CO_(2) *** work provides fresh insights into the PEC system design to reach the multi-electron reduction reaction and facilitate the C-C coupling reaction toward high-value multicarbon(C2+)chemical production via CO_(2) conversion.

摘要：根据阜山金矿地质资料，用有限元法模拟了不同采充高度采场的应力场和位移场．结果表明：采用尾矿充填并配合上盘锚杆是维护围岩稳定性的有效方法；合理的采夫高度是分层高度为4m，最大控顶距为6m．该结论可用于指导采场的设计．
