Reservoir deep profile technology

The technology was first put forward by the United States and large-scale commercial applications. Since the early 1970s, began using the polymer plugging, chemical machine for pellets and profiling technology has developed rapidly, has become a high water cut oil field water flooding effect to improve the dominant technology. Currently, for different reservoir profile control agent developed many types and plugging agent, for example, a polymer gel, particle type, precipitation, and microbial agents and foam and the like. In addition to the development of various types of blocking agent, but also on the water shutoff profile abroad mechanism of decision-making technology, Tracer monitoring technology, construction technology, oil expeller and implantation process is carried out a systematic study of the formation of a relatively complete water shutoff sectional supporting technology. China in recent years have done a lot of work, forming a series of technology, in the colloidal dispersion of solid particles in the gel and the gel has its own characteristics, but technically still a gap with foreign countries.

Sulfonated crude sulfonation method and the two-step method

(1) white oil production by-products method. In the production of white oil refining using sulfonation process, removal of aromatic hydrocarbons in the feedstock oil and other active ingredients, is the main product is a mineral oil and Food dehydrator, in the water phase is mainly petroleum sulfonate. Such petroleum sulfonate average relative molecular mass between 400 and 580 for over sulfonate. Flooding EOR used as a surfactant required, the need for a certain degree of modification. (2) crude sulfonation. Generally having a boiling point of 210 ~ 500 ℃ reduction in second distillate as a raw material, the direct use of sulfur trioxide or fuming sulfuric acid sulfonation, and then the obtained alkali alkyl aryl sulphonates. The method of using the raw oil refining production petroleum sulfonate, its treatment process for the heavy - Distillation - hydrogenation - furfural refining - sulfonated - and in other procedures. The petroleum sulfonate prepared sulfonated crude product performance with different nature are machine for pellets. High aromatic content naphthenic crude oil, petroleum sulfonate production byproducts less easy to obtain with the formation of ultra-low interfacial tension of oil products; while paraffin base crude oil aromatics content, the production of by-products of petroleum sulfonate up to 60% , high production costs, in terms of economic and process by-products is limited. (3) two-step sulfonation. First, the Act of crude oil in the catalyst reacts with SO2 and Cl2, the crude oil alkane sulfonyl chloride generated, then SO3 sulfonation of aromatic hydrocarbons in the crude oil to generate sulfonated aryl sulfonates, obtained by NaOH. alkyl sulfonates and aryl sulfonates. Advantage is that the entire fraction can generate oil sulfonates, sulfonated integrated conversion rate of 70% or more, reducing by-products, reducing costs. Petroleum sulfonates prepared above three method of standard products concentrate active matter content is generally 60% to 63%, about 35% of saturated hydrocarbons, about 2% to 5% moisture content. But it can be made up to 80% active matter content, and as 30% of the products used directly.

Preparation of alkyl benzene sulfonate EOR

Synthetic sulphonates include alkyl benzene sulfonates? Alkyl sulfonates? Heavy alkylbenzene sulfonate, etc., wherein the alkyl group having a carbon number of C14 ~ C16 alkylbenzene sulfonic acid weight Salt can be used with the majority of our crude Oil processing  ultra-low interfacial tension system, which has become an important surfactant flooding. Heavy alkylbenzene sulfonate production methods based on different raw materials are mainly three kinds, as described below: (1) dodecylbenzene production method. This method is the main raw material in the production process oil expeller production accounts for about 10% of alkylbenzenes. Dodecylbenzene heavy alkylbenzene with different production methods, composition and structure are very different. (2) UOP method. The method is based on kerosene as raw material, through hydrogenation of unsaturated materials removed, and dehydrogenation into α-olefin, and then with benzene alkylation of benzene production process, is currently the more popular methods. Dodecylbenzene using this method obtained when producing heavy alkylbenzene, alkyl having a carbon number in the C14, mainly around ingredient C17, is a straight-chain alkyl-based alkyl compound, as well as some polyalkyl ? alkyl benzene and alkyl benzene rings connected with an alkyl compounds. (3) wax lysis. With wax cracking as the alkylating agent, and benzene in the catalyst, after Fourier AlCl3 catalyzed reaction alkylbenzenes having a molecular weight than kerosene obtained product as a raw material is high, an alkyl group having a carbon number in the C15 ~ C20, C17 which ~ C19 as a main component.

oil refinery and other environmentally friendly


Hebei Province, " second five " plan made ​​it clear that the development of bio- processing , environmental monitoring and other environmentally friendly technologies and products , the positive nmb crude oil production of renewable resources, recycling and remanufacturing use of technology, establish and improve the energy saving technology innovation, product promotion services system. Development of photovoltaic power generation , biomass and waste to energy . Talking about the development of environmental NMB machine for pellets industry and his 10 years walked away looking forward told reporters that he is now considering how to make the most out of straw pressed more " treasure ."

oil extraction nutrients out


Oil nutrients single soybean salad oil . Salad oil is also commonly used cooking oil, experts, salad , also known as " one oil" ( the new national standards ) , the manufacturer of soybean oil to remove special beany through eight procedures refined soybean oil , so that it becomes colorless, odorless oil types . So many of soybean oil itself nutrients inevitably be " refined out " , and crude oil production  favorite " Bean " taste is gone.
Judging from the nutritional value of soybean oil fatty acid composition is better, it is rich in polyunsaturated fatty acids , have the effect of preventing cardiovascular disease , but also contains large pellet mill machine of vitamin E, vitamin D, and rich in lecithin, both to human health beneficial . Meanwhile, experts also stressed soybean salad oil types are not the flavor , not as good as the quality of edible sesame oil , sunflower oil, peanut oil, soybean salad oil and because of the high saturated fatty acids , but also requires other kinds of edible oil .

Concrete mixing stations and OEMs


Construction machinery : Last week we rushed to Guangzhou , Nanchang, Changsha , research local dealer , concrete mixing stations and OEMs , the main conclusions : ( 1 ) in the first half of this year sales of construction machinery will be a modest recovery , demand is relatively crude oil production little digging ; ( 2 ) Dealers tend to control risk, and sales policy conservative . The possibility of a price war this year is very small ; ( 3 ) inventory down to a reasonable level , the dealer chain pressures eased significantly funds . However, this is subject to the real estate control policies , the short-term share price downside risk of mechanical engineering , the proposed bargain concern Zoomlion .
Oil and Gas Equipment : Last week we visited the domestic oil and gas experts , concluded that : ( 1 ) the next 3-5 years, the average annual growth rate of consumption will exceed 20 percent , natural wire stripping machine  be the focus of China's short-term alternative energy development ; ( 2 ) LNG operations and profitability barriers are very high , small liquefaction plant facing rare opportunities for development ; ( 3 ) China will gradually increase investment in shale gas open , positive fracturing equipment , downhole tools and related services ; ( 4 ) China openness is the trend of rising oil system , private enterprises have a huge room for growth.
