The constitution, operating principle, technical parameters and operating technology of the truck mounted well pumping equipment are introduced. The equipment can be used for increasing the production of low producing wells, low energy wells and edge wells in old oilfields. It is also suit to the swabbing of exploration wells, the depressurization and augmented injection of water injection wells and the flowing back and plugging relief of new wells.
Through the analysis to two typical questions of water flooding in Zhongyuan Oilfield, this paper explains suitability of the new type chemical plugging agent-YLD-1. With lab test, author mainly demonstrates the properties, distinguishing features and principal functions of the agent, and then deeply discusses the principle of selecting wells and operating technology. Through on-side application in Wenliu Oilfield, the article demonstrates nicely developing prospects of the technology.
Combined with practical engineering,this paper introduces the basic component,operating principle,technical performance and characters of HZS75B full automatic concrete mixing station,illustrates its operating technology,points out its construction notices,and proves by practices that premixed concrete technology has well application effect and is worthy to be popularized and applied.
According to constructing experience in recent years, the causes of percolation in waterproofing concrete structure underground are revealed. That is not only relating with the choice of waterproofing concrete, but also with other raw materials (e.g. sand, stone and cement) closely. The operating technology and detail treatment in the construction are important similarly.
The function and operating technology of cement squeeze in Caracoles oil field administrated by CNPC America Ltd. Venezuela and an actual example of plugging perforations by cement squeeze in the oil field are introduced in the paper. A total of 125 well time cement squeeze works had been carried out from 1998 to 2001 in the oil field with a success ratio of 100%.
Abstract The paper introduces operating technology and the key to the technology of smelting low Al FeSi(containing Sr)by one step method in a submerged-arc furnace. Instead of traditional method,one step method has achieved remarkable economical benefit.
It is a common pitfall of instructors to focus on only one site during the complex process of managing the class and operating technology.
At issue is the fact that operating technology for accelerators in the laboratory can be underestimated in the transition to the clinic.
It synthetically states the reformation on the structure and the operating technology of small Si-Fe furnaces which have been working for many years. It can be referred by the other ferro-alloy factories.
This paper presents the situation of high voltage switchgear operating technology achievements in China. It gives an overview of the future development according to the condition of the networks. This paper can be used as a reference for engineers who are engaged in either developement of new HV switchgear or operating technique.
The change of the colloidal silicate in heating and its action on permeable cermet have been investigated and compared with the ethyl silicate binder. The results of the test have shown that the operating technology for colloidal silicate binding is comparatively simple and the strength and gas permeability of the mold are comparatively good.
