With the increasing exploration and development efforts in Jungar basin, the exploration and development objects are becoming more and more complex, the reservoir quality is becoming more and more diverse, the coexistence of "low porosity, low permeability, low production" and "high temperature, high pressure and high production" is presented, and the well conditions and working conditions are getting worse, which leads to the increasing difficulty of exploration and development. At the same time, limited by the unfavorable factors such as the difficulty of field data acquisition and low utilization degree, after comprehensive benefit evaluation, our company combined with the field experience, compiled a practical program to conduct real-time analysis for the field test data, quickly evaluate the reservoir, effectively identify and prevent the risks, correctly guide the field production, and ensure the successful production of safety oil test operation and post well completion.
At present, the lower southern margin of Jungar basin has made a historic breakthrough, showing great exploration potential and bright prospects. However, the geological conditions in the southern margin of Jungar basin are complex, and the understanding of exploration is low. Through technical research on the target block and breaking through the bottleneck technical problems, the matching technology for oil and gas reservoir testing of the middle lower combination reservoirs in the southern margin of Jungar basin will be initially formed, which will provide support for the construction of large oil and gas areas in the southern margin.
