胡状集油田胡十二块以调剖堵水为中心的综合治理研究   总被引:2,自引:0,他引:2  
分析了胡十二断块的油藏动、静态资料;运用数位模拟法搞清了油层剩余油分布状况;通过示踪剂试验证明区块中存在大孔道;并进行了粘土试注试验,选择了合理的堵剂。在以上基础上确定了该油田以调剖堵水为中心的综合治理原则,制定了优化堵水方案。经现场封堵大孔道工艺措施的实施,不仅改变了水流方向,改善了吸水剖面,增加了水驱动用储量,提高了油田最终采收率,而且使地层能量得到补充,产量有所上升,取得了满意的综合治理效果,并获取了较大的经济效益。  相似文献

每当太阳从东方升起,在地球上生存的每一个人,又都会开始新一天的生活。“眼睛一闭一睁,一天过去了;眼睛一闭不睁,一辈子过去了”,噢,人生真是苦短啊! 说起人生之苦和世道之难,感叹不已。今年不知怎么搞的,苦和难好像一个个排着队涌来。核弹竞赛真来了,恐怖袭击加剧了,飞机空难重演了,地震频率加快了,山体滑坡厉害了。暴风骤雨更猛了,能源争夺空前了,空气污染天昏了,股市行情难猜了,房价居高不下了,今年夏天热坏了,就连酒后驾车的人也多多了。嘿,怎一个“了”字能了得?  相似文献

中亚土库曼斯坦阿姆河右岸气田群为高含H_2S和CO_2的碳酸盐岩气藏,单井产量高,井口设备均出现了不同程度的腐蚀。初步分析认为其原因是生产过程中仅考虑酸性介质对气井井口的化学腐蚀,而没有考虑气体流速对井口的冲蚀作用,极大地影响了气田的安全生产。为此,通过对节流阀上下游阀道、法兰面均出现明显坑状腐蚀的进一步分析,明确了化学腐蚀和气体冲蚀的交互作用是井口磨损的主要影响因素,气流冲刷腐蚀坑的化学腐蚀产物会加速冲蚀损害;进而借鉴冲蚀与腐蚀运行环境下的多相管流管道的磨损计算理论,计算了该运行环境下的冲蚀极限速度,得到了不同生产工况下节流阀的抗冲蚀流量;最后,根据气田生产情况,针对性地提出了按气井配产要求来选择采气树类型、节流阀通径及类型冲蚀的技术控制策略。此举为气田安全生产提供了工程技术保障。  相似文献

针对山前地区深井超深井钻井过程中套管磨损严重的问题,在分析套管磨损机理的基础上,开展了山前地区套管防磨与减磨技术研究,基于技术研究成果及应用实践,得到如下结论:1应用Power V等垂直钻井系统控制井眼轨迹,特别是上部井段的狗腿度和井斜,可明显减小侧向力和磨损量,缩短套管磨损时间;2应综合考虑套管磨损率、磨损系数以及钻杆耐磨带本身的磨损量,优选出效果最优的耐磨带;在狗腿度严重的位置,可考虑采用一定数量的橡胶钻杆卡箍来减轻对套管的磨损;3山前地区钻井液采用CX-300减磨剂能够显著降低磨损速率,减轻套管磨损程度,但在不同钻井液体系使用之前应进行优化分析以确定最佳使用量;4在迪那204井使用高密度钻井液体系,全部采用优选的高密度重晶石粉代替铁矿粉作为加重剂,整个钻进过程中未出现钻具及套管磨损,迪那204井易损件消耗量仅为邻井迪那203井的左右,防磨减磨效果非常显著。  相似文献

Nearly 7,000 hectares of biodiesel forest will take shape in the northern province of Hebei in 2008, part of a national campaign to fuel the fast growing economy in a green way. In no more than five years, the Pistacia chinensis Bunge, whose seeds have an oil content of up to 40 percent, will yield five tons of fruit and contribute about two tons of high-quality biological diesel oil, according to the provincial forestry administration.  相似文献

Experts recently suggested China set up a state energy base in lnner Mongolia Autonomous Region to ease its energy thirst. The survey was co-conducted by senior researchers from the National Development and Reform Commission, Development Research Center of the State Council, Chinese Academy of Sciences and the Ministry of Finance. To plan and establish strategic energy bases at state level is in line with the principle of "giving priority to energy saving and diversifying energy consumption with the utility of coal at the core."  相似文献

Carbon deposition is a commonplace phenomenon occurringin the catalytic reaction process, in particular inthe system of direct dehydrogenation of ethylbenzene,because the reactant - ethylbenzene molecules on thesurface of metal oxide catalysts are prone to quickly formcarbon deposits, leading to deactivation of catalysts. Recently,the associate research fellow Mr. Liu Hongyangand the research fellow Mr. Su Dangsheng of the StateShenyang Material Science (United ) Laboratory of theInstitute of Metal Research, CAS by taking advantageof the carbon deposition process during direct dehydrogenationof ethylbenzene have ingeniously designeda Pd/C composite catalyst. This catalyst in comparisonwith the traditional commercial carbon nanotubesupported Pd catalyst shows a significantly improved performancein terms of its catalytic activity and sinteringresistantability.  相似文献

China and Brazil celebrated the 40th anniversary of establishing diplomatic relations between the two countries in July this year. Bilateral relations between China and Brazil have entered a new stage, and experts expect the already extensive cooperation between the two countries to deepen and broaden as Chinese President Xi Jinping made a state visit to Brazil in mid-July, which is his first state visit to Brazil since he assumed the office last year. The visit to China's largest trade partner in Latin America is at the invitation of Brazilian President Dilma Rousseff.  相似文献

The role of equipments in oil and gas exploration and development had never been attached with so much importance as that in shale oil and gas boom in the U.S. With the help of massive hydraulic fracturing and horizontal drilling techniques, the U.S., the world's No. 1 oil importer even started to dream about energy self-sufficiency with its proudly high production of shale oil and gas from several major shale plays in the country. However, what behind this remarkable achievement are powerful multi-stage hydraulic fracturing machinery and smart tools for directional drilling.  相似文献
