Development Goals——for the Non-ferrous Metal Industry During the Ninth Five-year Plan

According to the Ninth Five-year Plan and 2010 Long-term Goal Program, the non-ferrous metal industry will focus on revamping and expanding its existing enterprises. Through systematic technical renovation, the industry will expand production capability, increase varieties, improve the recovery of waste metals, and do a good job of

SHAANXI'S KEY PROJECTS FOR FIXED ASSETS INVESTMENT DURING THE NINTH FIVE-YEAR PLAN

During the Eighth Five-Year Planperiod, Shaanxi Province intensifiedthe restructuring of investment andmacro-control in fixed assets investment byimplementing the policy of "limiting totalamount, readjusting structure, rectifying orderand improving efficiency". The wholeprovince realized RMB 110 billion in fixedassets investment, (including RMB 86.5 billionby state-owned units, RMB 14.23 billionthrough loans from the construction bank,making up 16.5 percent), RMB 67 billionmore than in the Seventh Five-Year Planperiod, with an annual increase of 26.5 percent.Thanks to the support, a group of medium-to-large and key projects have been put

CHINA'S NON-FERROUS METALS INDUSTRY——Its Development Policies and Goals During the Ninth Five-year Plan Period

The China Non-ferrous MetalsIndustry Corporation has putforward ten development policiesfor the Ninth Five-year Plan period,according to the central government’sinstruction to change the way of economicgrowth,and raise the integral quality andbenefit of the national economy:

China's Strategic Measures to Develop Coal Industry During the Period of the Ninth Five-Year Plan

A reporter for China’s Foreign Tradehas learned from the Ministry of theCoal Industry that China will takethe following steps to develop its coal industryduring the ninth five-Year plan period. 1. To regulate the policy for buildupthe coal industry and to make a good job ofthe comprehensive development of buildinga number of key coal production bases.

Development of China's Food Industry——Focal Points For China's Food Industry Development During the Ninth Five-Year Plan Period

1.Products of the basic rawmaterials industry Products of the basic raw materialsindustry should improve product quality,make great efforts to realize diversification,serialization and specialization in productvariety,develop new varieties,and expandproduction so as to adapt to the demands forthe development of the food industry. Cereals:Develop high quality riceand wheat flour on a grade and class basis;develop special rice and wheat flour suitablefor the needs of processing various kinds offood;actively utilize coarse cereals such ascorn to open up various kinds of

Objectives of China's Light Industry Under the Ninth Five-Year Plan

Through the last 17 years of development,China’s light industry has basicallyresolved the short supply of consumergoods,with market demand having been metin quantity,but not in quality.How to adaptto the changes on both the domestic and theinternational markets,speed up structuraladjustment and optimization,promotetechnical progress,develop new products,improve quality,and raise grades andprocessing standards,is the main task for thedevelopment of the light industry in the next15 years.

MARKET PREDICTION FOR CHINA'S MACHINE-BUILDING INDUSTRY IN THE NINTH FIVE-YEAR PLAN PERIOD

In the mid- and late 1990s,China’s nationaleconomy will maintain sustained,rapidand healthy development in terms of itsoverall capacity.This has provided idealopportunities for the development of China’smachine-building industry.These include:

The Goal Set For China's Coal Industry During the Ninth Five-Year Plan Period

Coal is China’s principal source of energy,accounting for about 75percent of primary energy.This pattern will remain unchanged fora long period of time from now on.Thanks to the efforts made duringthe Eighth Five-Year Plan period,the general situation for the coalindustry is now good.

Calculating single layer production contribution of heavy oil commingled wells by analysis of aromatic parameters in whole-oil GC-MS

Traditional fluid production profile logging is not usually suitable for heavy-viscous crude oil wells.Biodegradation of heavy oil can lead to the loss of n-alkanes,and the use of chromatogram fingerprint techniques in studying the production contributions of single layers in heavy oil commingled wells has limitations.However,aromatic compounds are relatively well preserved.We took the heavy oil commingled wells of small layers NG55 and NG61 in the ninth area of the Gudong oil field as examples.Based on the principle of chromatography,the whole-oil GC-MS was used,and the aromatic parameters which have a strongly linear relationship with the ratio of mixed two end member oils were verified and selected in laboratory.Studies showed that the ratio of （1,4,6-＋ 2,3,6-trimethylnaphthalene） to 1,2,5-trimethylnaphthalene has a strongly linear relationship with the ratio of the mixed two end member oils （R2=0.992）.The oil contributions from single layers NG55 and NG61 in six commingled heavy oil wells were calculated using established charts and this relationship.The calculated results are consistent with the results of long period dynamic monitoring and logging interpretation in the study area and can provide a scientific basis for monitoring production performance and hierarchical management of reservoirs.The study provides a new geochemical method for calculation of the contributions of single layers in heavy oil commingled wells when conventional fluid production profile logging is not suitable.
