PetroChina Inks Bio-Fuel Deal with the State Forestry Administration

11 January 2007, Beijing - PetroChina Company Limited （PetroChina） signed a framework agreement with the State Forestry Administration （SFA） on the development of forest bin-fuel and officially kicked off the construction of the first batch of forest bio-fuel tree breeding bases in Yunnan and Sichuan, marking a substantial step forward in the cooperation of forest bio-fuel development between the two parties.     

China Holds Exercises of Oil Spills Emergency Control

Chinese emergency services carried out their largest ever exercise in early June to tackle an oil spill in the Bohai Sea to test their ability to protect the ocean environment. The drill involved a scenario in which a 10,000-ton oil tanker exploded and spilt 500 tons of oil. Soon after the oil tanker Tianpeng ＂exploded＂, a fireboat arrived to fight the fire and a helicopter hovered above to spread chemicals to control oil spill, followed by more vessels and another helicopter.

开采稠油并原地提高原油品位的新技术

THAI（“Toe-to-Heel”Air Inuection）水平注空气技术是一项重力辅助的火烧油层工艺。它结合了水平井先进技术以获得潜在的、极高的稠油采收率；通过热裂化实现原地提高原油品位、开采出改质的原油。该工艺利用重力稳定性原理限制向狭窄的可流动区域泄油，这样就可以使已经处于流动状态的流体直接进入了生产井的裸露井段。该工艺可用于一次采油、作为现代技术的配套技术或作为热效率要求高的工艺的配套工艺。该技术能够凝聚能量，使原油在油藏中流动、采出和热力升级。THAI中还结合了清洁技术。因此，该技术为稠油工业提供一条新的、成功的路。     

新型反渗透阻垢剂阻CaCO3性能评价研究

提出了一种间歇排出部分产水的循环模式的新型方法，来进行反渗透阻垢剂的性能评价，并以模拟浓水作为进料水，在不同操作条件下?对新研制的环保型阻垢剂TJ—1、TJ—2阻碳酸钙性能进行了评价并与美国清力公司的PTP2000作对比．试验表明此评价方法快速简单，TJ—1、TJ—2可达到与PTP2000相近的阻垢性能，并具有很大的价格优势。
