数据库设计是斜井有杆泵抽油参数系统开发的关键环节.针对斜井有杆泵抽油的生产过程,利用ACCESS设计的关系型数据库系统由三大基本模块及40多个数据库组成,主要包括斜井基础数据管理、参数动态分析、绘图管理、参数配置管理、报表管理及用户管理等功能.通过油田现场应用表明,该系统在杆管偏磨分析、绘制井眼轨迹、扶正器和防脱器间距及数量等方面的分析与计算有良好的效果,同时可为斜井有杆泵抽油生产中的参数选取和优化提供帮助. 相似文献

强碱三元复合驱结垢对机采井的影响及解决措施 总被引:3,自引:1,他引:2
强碱三元复合驱油技术可以大幅度提高采收率,但在机采井举升方面暴露出结垢的问题,抽油机井频繁卡泵,螺杆泵井频繁断杆,对生产造成了较大影响.为明确结垢对机采井产生的影响,并进而研究解决措施,首先对三元复合驱机采井结垢现象及结垢特点进行了阐述,从抽油泵结构及卡泵发生的时机方面,对抽油机频繁卡泵的原因进行了分析;对于螺杆泵井,从定子转子间运行扭矩的相关参数及现场生产情况综合分析,提出了螺杆泵频繁断杆的原因.通过研究,在螺杆泵井上提出小过盈螺杆泵的概念并加以应用;在抽油机井方面,研制并现场试验了井下缓释固体化学防垢块和防垢泵等措施.现场应用后,油井免修期得到了明显的延长,取得了明显的效果. 相似文献

Thermal techniques (differential scanning calorimetry (DSC) and the vacuum stability test (VST)), according to STANAG 4147, and non-thermal techniques (Fourier transform infrared (FTIR) spectrometry and X-ray diffractometry (XRD)) were used to examine compatibility issues for 2,4,6,8,10,12-hexanitrohexaazaisowurtzitane (CL-20) with a selection of insensitive explosives, including nitroguanidine (NQ), 2,4,6-trinitrotoluene (TNT), 2,6-diamino-3,5-dinitropyridine-1-oxide (ANPyO), 2,4,6-triamino-1,3,5-trinitrobenzene (TATB), 3-nitro-1,2,4-triazol-5-one (NTO) and 2,6-diamino-3,5-dinitropyrazine-1-oxide (LLM-105). DSC measurements showed that ANPyO, TATB, NTO and LLM-105 were compatible with CL-20. The compatibility of CL-20/NQ, CL-20/TNT, CL-20/ANPyO, CL-20/TATB, CL-20/NTO and CL-20/LLM-105 mixtures was further explored using the VST, which revealed that all the selected insensitive explosives were compatible with CL-20. Possible chemical interactions were suspected for CL-20/TATB from the FTIR results and for CL-20/NTO from XRD analysis. In summary, ANPyO and LLM-105 demonstrated the optimal compatibility with CL-20. 相似文献

Abstract Eight shale samples related to the Duwi Formation (Campanian-Maastrichtian) of the Abu Tartur mines of the southwestern desert of Egypt were petrographically, mineralogically, and geochemically studied. The study results indicate that the detrital material of these shales were derived mainly from mafic to ultramafic components of the basement rocks under intensive chemical weathering and deposited in an alkaline reducing marine environment of low energy and these shales do not attain the requirements of hydrocarbon production. 相似文献

Abstract API gravity, sulfur content, gas chromatography, and gas chromatography-mass spectrometry analyses were carried out for eight oil samples collected from different wells in the Gulf of Suez. The results showed that two types of oils could be recognized: (a) heavy oils, which are oils from Zafarana, Rahmi, West Bakr, and Ras Gharib wells, are of low maturation and originated mainly from terrestrial organic sources; and (b) light oils, which are oils from Um El Yuser, Ras El Ush, Gemsa-SE, and Hurghada wells, have a high level of maturation and orginate mainly from marine organic sources. 相似文献
