Counter-seepage technology has already been widespreadly applied in each domain. In my factory,it uses the counter-seepage aqueous plant to provide Mizhi shifts the life tap water.Also it has the very vital practical significance regarding the counter-seepage research.This article mainly introduces to the counter-seepage installment that make us understand counter-seepage technical process from my factory.In through the production present situation description record,the counter-seepage installment the movement deficiency is discoversd.And actual counter-percolating water returns-ratio is also obtainsed in my factory. We found the primary factor which has affected my factory energy conservation festival consumes.Finally In order to daily production service,we analyze the common accident of the counter-seepage installment in the production.

Swept away accumulated ash of convection fragment wings pipes surface of ethylene furnace from stove by using chemical cleaning methods,reduced the discharging smoke temperature of ethylene furnace,which increased the heat conduction properties of convection pipes,and ethylene furnace heat efficiency.

Aerated drilling is a kind of underbalanced drilling means that the density of cycle mud is less than 1 g/cm~3.It is important to fasten the drilling speed and shorten the drilling period for saving investment of well drilling process.There is a huge circulation loss in liujiagou Formation which has constrainted the development of the zizhou-mizhi gasfield. Attempting use the aerated drilling should be a good methd to solve the problem.In the year of 2008 aerated drilling technology is widly used in this block.Application in some wells,it indicate that aerated drilling can reduce formation damage,increase drilling speed and be suitable for low pressure,low permeability as well as easily leaking reservoir.

The natural gas pipeline anticorrosion technology of Yulin gas field is mainly use the method of adding insulating course and protecting cathode.This paper introduce the ways about pipe of multifrequency's electric current and the thchnique of natural gas pipeline anticorrosion layer.Yulin gas field have used these thchniques to test the Piping cathodic protection potential,evaluate effect of cathodic protection,realize the pipeline's anticorrosive coating and flaw condition and then carry out excavation and repair.This technology is simple,practical and exact in guiding the gas safety production.

The causes and mechanism of coking of pyrolysis gas compressors were presented,the coking problems were solved using the retrofit technology of interstage water injection and parallel connection of heat exchangers.

The oil-in-place of oil shale resources in the Bag Mod area of Inner Mongolia amounts to 2.3×108 t,and the recoverable reserves is up to 1.2×108 t.Through in-depth investigation and analysis on the oil shale in this area,petroleum researchers concluded that although oil shale distributes in a wide vast area,oil content is only 3.9-5.3% belonging to low-grade resources,the conventional recovery technology of oil refinery by the Fushun Furnace is not adaptable but many different techniques can be integrated into use for oil shale recovery here.Based on the analysis of 100 samples,the heat values of which range from 1807-6918 kJ/kg with an average of 3606.5 kJ/kg,the result demonstrated that most samples have low heat values so they can not be burned directly but can be combusted if being mixed with the coal by the burning technique of Circulating Fluidized Bed.According to the sample analysis on the volatile content of oil shale in this area,this study showed that Bag Mod oil shale with medium volatile content can be widely used in architecture.

In the paper, mainly from the closure and opening force analysis of methane pump mechanical seal failure causes were discussed, and for its proposed improvement measures, the mechanical seal reliability and security were improved, extended the useful life of mechanical seals, and achieved good benefits.

Buried pipelines get chemistry corrosion and electrochemistry corrosion.It need the way of external daub anti-corrosion painting layer and cathodic protection to defend corrosion of the buried gas transmitting pipelines.The paper expounds simply the coorodent reason and catohodic protection truth or system.Analyzes and value system in the south of Yulin the elements of cathodic protection technics,then analyzes briefly puts forward some optimition proposals.
