Oil Recovery & Production

Sand Control Technology

Loose sandstone and long-term water flooding oil wells will cause a large amount of sand production in oil wells. In order to prevent sand production, on the one hand, correctly choose cementing and completion methods according to oil layer and oil well conditions, then make reasonable production measures and control production pressure difference; On the other hand, according to the requirements of the oil layer and the production process, the corresponding sand control technology is adopted to ensure the normal production of the oil well.

Oilfield Digitization Technology

Oilfield digitization can generally be described as: taking oilfields as the research object, using computers and high-speed networks as carriers, and using spatial coordinate information as a reference to highly integrate various data of oilfield production and management. Based on the establishment of various optimization models of oilfield production and management processes, simulation and virtual technologies are used to visualize data in multiple dimensions, so as to realize the horizontal coverage of the entire oilfield area, and the vertical position of the oilfield from the ground to the underground. The overall information analysis capabilities of the oilfield to support the in-depth needs of key businesses such as oilfield exploration and development. As a whole, it assists the decision-making analysis of oilfield operation and management, and further explores the potential value of each link to create a good information support environment for the sustainable development of oilfield enterprises.

Crude Oil Demulsification Technology

Because some solids are difficult to dissolve in water, when one or more of these solids exist in a large amount in the aqueous solution, under the agitation of hydraulic or external power, these solids can exist in the water in an emulsified state to form an emulsion. Oil-water mixtures and water-oil mixtures will form a relatively stable water-in-oil or oil-in-water structure in these two phases. The theoretical basis is "electric double layer structure". In this case, add some medicament to destroy the stable electric double layer structure and stabilize the emulsified system, so as to achieve the purpose of two-phase separation. This kind of technology is called crude oil demulsification technology, and these agents for destroying emulsification are called demulsifiers.

Free Sand-fixing Technology

Sand control in powder sandstone, argillaceous fine sand rock oil well and gas well development has always been a difficult problem In the case of fine sand, the sand filter pipe will be seriously blocked, and the production capacity will decrease rapidly after being put into operation The problem of gas well is more prominent, due to the blockage of the sand filter pipe, the production capacity is reduced rapidly on the one hand; on the other hand, the other blockage of the other side causes partial concentration of the gas pressure, and the sand-filtering pipe blow-through will cause the sand-proof failure, which is a serious problem that is common and difficult to solve The problems mentioned above can be solved effectively by shaft block-free chemical sand-fixing technology.

Improve Polymer Injection Effects

The conceptual scheme is mainly aimed at T oilfield polymer flooding test area at South America. In early stage, most wells had response, and the overall fluid and oil production in pilot area increased. In mid-to-late stage2C multiple wells had a sharp rise in polymer concentration and glide in oil production.The results of pilot test differ from prediction. The water cut almost reached 90 until 2014 After a comprehensive analysis of information, find out the question crux. According to different conditions, puts forward some countermeasures to improve the effect of polymer injection and the follow-up research work.
