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.

EOR oil carboxylate Preparation

Carboxylate by petroleum oil fractions by high temperature oxidation, and then by saponification? Extraction of the product obtained. It belongs to the oxidative cleavage product saturated hydrocarbon complex composition mainly containing an alkyl carboxylate salts and aryl carboxylate salts. Production of oil carboxylate main raw material for regular oil expeller and second-line fraction to vapor phase or liquid phase oxidation oxide production. Vapor phase oxidation process with oxygen in the air as oxidant at 325 ℃, oleic acid cadmium oxide as a catalyst, the oxygen / hydrocarbon ratio of 2.20, the water / hydrocarbon ratio of 25 to 50. After the reaction product was saponified with NaOH to remove the oil phase, to obtain petroleum products carboxylate, effective content was 10%. Liquid phase oxidation in the vapor phase oxidation process is a process based on a new method developed by liquid oxidizing agent to conduct the reaction at 180 ℃, the machine for pellets of carboxylate may be raised to 20%. Oil is an important carboxylate cosurfactant, together with synthetic alkylbenzene sulfonates, can increase the stability of the surfactant system? Dilution resistance and compatibility with a base.

Preparation of EOR petroleum sulfonate

Petroleum sulfonate is a crude oil or fractions rich sulfonated aromatic product obtained aromatic compounds whose main component is a single salt, which has an aromatic ring with one or several five-membered ring fused together, there are two aromatic ring with one or more five-membered ring fused together, compared to the rest of aliphatic hydrocarbons and oil equipment hydrocarbons sulfonated or oxide. Currently the main use sulfonation, there were three kinds of preparation: white oil production byproduct France? 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 machine for pellets, 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 very different. 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 Pellet mill 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.

Peanut oil squeezed out of the amount of zinc

Chinese Academy of Preventive Medicine study confirmed peanut peanut oil press are squeezed out of the amount of zinc is 37 times salad , corn 32.6 -fold, 16 -fold rapeseed oil , soybean oil seven times . Although zinc many ways , but the fat is necessary for people's daily supplement , so eating peanut particularly suitable for public zinc. Nutrition experts also found in peanut three kinds of beneficial health components cardiovascular : Resveratrol , rich in monounsaturated fatty acids and  potato peeler machine  . Experiments show that these types of substances are cancer chemopreventive agent class of diseases , but also reduce platelet aggregation, prevention and treatment of atherosclerosis and chemopreventive agent for cardiovascular and cerebrovascular diseases , and is ideal for the elderly one of edible oils and fats . Peanut oil contains a variety of high-quality anti-aging ingredient , has the effect of delaying the aging brain function . Per 100 grams of peanut oil contains about 0.1 grams of water , energy ( energy supplement products,  donut maker machine  information ) is 3763.9 kJ, 99 g fat , 0.6 g carbohydrates , vitamins ( vitamins , vitamin info ) 7.64-58.7 mg, otherwise varying amounts of calcium ( calcium products , calcium supplements information ) , phosphorus, iron ( iron products, iron information ) , zinc ( zinc products, zinc information ) and other substances. The fatty acid composition of peanut oil beneficial to humans , of which more than 80% unsaturated fatty acids, oleic acid content of 412% , accounting for 376% of linoleic acid .
