CNPC Sees Crude and Natural Gas Production Rising Steadily

China National Petroleum Corporation （CNPC） firmly consolidated its dominant position in the country＇s oil and gas production sector in 2008. The largest oil producer in China sees an increase of 466,700 tons in its domestic crude output in the first half over the same period a year earlier. CNPC, the parent of PetroChina, said its production had met 50.03 percent of the full-year target despite the worst snowstorm in more than five decades from January to February and the massive Sichuan earthquake on May 12.     

CNPC Effectively Operates Worldwide

CNPC rapidly expanded its overseas oil and gas operation in 2001. The annual crude and natural gas outputs from the overseas projects were 16.23 million tons and 926 million cubic meters respectively while the crude processing volume was 2.3 million tons. Based on those oil and gas output, CNPC shared 8.31 million tons of equity crude and 577 million cubic meters of equity natural gas last year, up 20.96 percent and 29.66 percent respectively from the previous year, with an annual oil and ga…     

A scenario-based clean diesel production strategy for China National Petroleum Corporation

Facing increasingly strict environmental regulations on transportation fuels,China National Petroleum Corporation(CNPC),the second largest supplier of petroleum products in China,needs to upgrade its transportation fuels.Using the scenario-based analysis method,this paper analyzes how the output and emission related properties,including cetane number,and sulfur and aromatics contents of diesel produced by CNPC,will vary with changes in the configuration of diesel production units in the next 5-10 years.The results showed that,to upgrade its diesel,CNPC needs to adjust its diesel pool by decreasing the share of fluid catalytic cracking(FCC) diesel and increasing the shares of hydrocracking(HDC) and hydrotreating(HDT) diesel.Furthermore,to produce ultra-low-sulfur diesel,straight-run diesel as well as poor diesel blendstocks such as FCC diesel and coker diesel should be hydrotreated before being blended into finished diesel.Developing highly efficient HDC and HDT catalysts and corresponding processes is the key to CNPC economically producing more and cleaner diesel.     

原油高频降粘常温输送技术

油中的水有两种存在方式,一种是以分子的状态溶解于油中,另一种以乳化状态存在于油中。利用高频信号在产生电场的同时施加一个旋转磁场,既能够对原油产生极化作用和电热效应,又能够使其具备磁化效应,因而有较好的降粘效果。原油高频降粘装置由产生高频电能的主机和对原油进行不间断高频处理的副机构成。主机和副机通过高频电缆连接,双路可同时输出。原油高频降粘技术应用于大庆喇嘛甸油田,经中国石油天然气集团公司油气评价中心测试,高频处理后的原油可降低输送温度 ３℃。喇嘛甸油田日产液 ２４．８ ｘ１０４_ｔ艺,每升温 １℃就需耗天然气１．４ ｘ１０４_ｍ_３ｌ／ｄ,因此全年可节省天然气 １５３．３ ｘ １０_５ｍ_３。又因原油的运动粘度降低 ５．６～ ６．２ｍＰａ· ｓ,摩阻降低１０％,故使大庆油田采油六厂增加不加热集输井６２口。

Brief Introduction of PetroChina Yumen Oilfield

Yumen Oilfield having been developed for 67 years since 1939,was the first natural petroleum base of CNPC. The cumulative production of crude oil was 520 thousand tons in the first ten years after new Cbina＇s foundation, taking up 95% of the overall production of the whole country in those days. In 1959, the crude oil production reached 1.4 million tons, which was 51% of China＇s crude oil in total. Since the 1960s, Yumen Oilfield has taken on the important mission of establishing big schools, big trial fields and big institutes, as well as producing new products and developing new techniques, accumulating knowledge and training special personnel and engineers. The Yumen experts in oil/ gas exploration and staff members have successively participated in great battles for oil exploration in Daqing Oilfield, Sichuan Basin in Sichuan Province, western China, Changqing OilfieId, Qaidam Basin, the Turpan Depression and have provided other oilfields in China with nearly 100,000 engineers and over 4000 sets of various equipments, which made Yumen Oilfield best known as the cradle of China＇ s petroleum industry. The Laojunmiao, Ya＇erxia, Shiyougou, Baiyanghe, Shanbei and Qingxi oil pools in Yumen Oilfield have been put into production one after another, and the crude oil production reached 780,000 tons in 2005.

采用计量新技术提升采注适应力

随着油田的不断开发,全油田综合含水持续上升,要维持一定的原油产量,势必造成油田产液量持续上升。由于油田开发常常存在"重油轻水"的现象,对注水工程调整改造的投资不足,多数油田注水系统设备及管网的腐蚀、老化等问题严重制约了油田的后期生产。通过对油田注水系统存在的主要问题进行分析,提出要维持油田的原油产量,必须维持一定的油田污水处理、污水回注的增长,使之与油田产液量的增长相适应的观点。从精准计量入手,加大注水井调整和作业力度,增加污水回注的注水井点,提高污水回注的应急能力,采用新式计量技术,降低计量误差,真正实现"注好水、注够水",最大限度地挖掘自身潜力,提高地面采注系统的适应能力,为油田可持续发展奠定基础。     

我国原油管道现状与展望

管道是原油运输的主要运输方式,是保证国家能源和战略安全的有效手段。世界原油管道主要分布在北美、俄罗斯和中东地区。目前,我国原油管道长约1.3×104km,主要由中国石油和中国石化两家公司运营管理,部分管道运行时间较长,存在一定安全隐患,个别管道长期处于低输量运行。2011年我国原油对外依存度为54.3%,首次超过美国。随着我国原油对外依存度的增加,西北、东北、西南、海上四大原油进口通道将进一步拓宽,国内配套管道将进一步完善,连接沿海港口和内陆炼油厂的原油管道将陆续建成。     

To Protect the Environment—the Bounden Duty of CNPC

Environmental Protection takes precedence during the production and operation
The idea of ＂humanistic, safety first and environmental protection prior＂ is the basic principle of environmental protection of CNPC. It is pointed out in the work report of CNPC that, ＂To strengthen the safety production, protect the environment and save energy resources is the inevitable requirement to thoroughly implement the scientific approach on development as well as an important aspect to transform the pattern of economic growth＂. To carry out environmental protection priority, the whole process of oil and gas production and the guarantee of national oil and gas supply as well as the sustainable development should be permeated with the work of environmental protection. Specifically speaking, CNPC guarantees the priority of environmental protection with ＂Six Priorities＂ in the process of production and operation.
