· Oilfield Digitization Technology

more >

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.

· Hydraulic brake PCP solution

· Free Sand-fixing Technology

more >

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.
