The necessity and reality of increasing the depth of crude oil processing by means of supercritical solvent extraction are discussed. The preliminary investigation results of supercritical solvent extraction of Daqing and Shengli residue are presented. A processing scheme is recommended in which the vacuum residues are extracted with solvent at supercritical conditions. The extracts can be used as the feedstock of FCC and the raffinats as the blending component of road asphalt.

Most of the heavy oil from Chinese crudes are good cracking feeds for their low sulphur content and paraffinic characteristics. Crude cracking and atmospheric residue cracking have been studied ever since the end of 1960's.This report reviews the recent research on reducing the coke deposition during residue cracking. By using a new series of zeolite catalyst, raising the riser temperature, lowering the reaction pressure, increasing the steam injection, improving the feed atomization, applying rapid separation and shortening the feed residence time, etc., coke yield has been significantly decreased both at the 0.24 ton/day pilot plant and commercial units. Metals passivation, especially for nickel has also been studied.The operation parameters and the product yields of residue cracking in three refineries are listed. Gasoline plus light cycle oil yields for two atmospheric residues and vacuum bottoms mixed feeds are 70~76%and over 80% in weight, respectively.

发展渣油催化裂化工艺是当前世界上石油炼制工业研究发展的主要趋向。结合我国原油中重油部分较多及其低硫高石蜡性质,开展渣油催化裂化研究是极为必要的。本文简要介绍了近年来我国渣油催化裂化工艺的研究及发展。为了进一步降低渣油原料裂化时焦炭的生成,使用了新系列的分子筛裂化催化剂,研究了提高提升管操作温度、提高再生温度及降低进料预热温度、降低反应压力、增加水蒸汽用量、改进原料雾化、采用产品快速分离及缩短反应时间等操作手段对生焦的影响。已在0.24吨/日中型装置及工业装置上取得了良好效果。金属钝化方法也进行了研究。渣油裂化工业装置数据列于附表。两种常压渣油为原料时轻质油收率为70~76%(重),掺减压渣油的混合原料轻油收率超过80%(重)。

Measures of enhancement recovery are discussed based on the analysis of the high rate of increase of our crude oil output and the development of wells of hi- gh output and zones with high rate of production. It is pointed out that the ge- neral trend of our oil field development in the last thirty years is one of gradual intensification and that to keep a sustained high rate of production through reg- ulation of output between pays, wells and zones conforms to the oil-water move- ment in highly heterogeneous...

Measures of enhancement recovery are discussed based on the analysis of the high rate of increase of our crude oil output and the development of wells of hi- gh output and zones with high rate of production. It is pointed out that the ge- neral trend of our oil field development in the last thirty years is one of gradual intensification and that to keep a sustained high rate of production through reg- ulation of output between pays, wells and zones conforms to the oil-water move- ment in highly heterogeneous multizone oil fields. Therefore, it is predicted that enhancement recovery shall remain an important approach to tap our oil potential in forthcoming years.

本文分折我国原油产量高速增长的特点,高产井、高速开发区的开发效果,讨论进一步强化开采过程的方法。指出我国注水开发油田三十年来的总趋势,是逐步强化开采过程。层与层、井与井、区与区间的高产接替,符合非均质较严重的多油层油田的油水运动规律。近期内进一步强化开采过程、仍然是挖掘油田潜力,提高油田开发效果的重要途径。
