Problems solved by technology
[0005] ① Interlayer interference in the wellbore is serious, and the single well production is low;
[0006] ②The oil reservoir is prone to water invasion, the oil production period without water is short, the production cycle of a single well is short, and the oil recovery rate of the oil reservoir is low;
[0007] ③The conventional production logging in the horizontal section is difficult, the cost is high, and the shutdown time is long;
[0008] ④ The hole size is small, the downhole space is limited, and conventional mechanical water plugging and plugging removal operations are difficult
However, due to the lack of corresponding theoretical support for intelligent well completion technology, and the conventional oil recovery theory is not suitable for the analysis of intelligent well completion systems equipped with downhole flow control valves
Therefore, it is impossible to adjust the nozzle opening combination of the downhole ICV valve according to the measured downhole real-time pressure and temperature data, and the various advantages of intelligent completion technology have not been fully utilized

The invention relates to a production fluid simulator of an intelligent well completion simulation system, comprising a sleeve, a throttle valve sleeve, a sliding sleeve, an adjusting screw and a connecting head; the sleeve, the throttle valve sleeve and the sliding sleeve are sequentially arranged from outside to inside Distribution, the connecting head, adjusting screw and throttle valve sleeve are set on the outside of the sliding sleeve in sequence from left to right. The advantage of the present invention is that the process of controlling fluid pressure and flow by the throttle sleeve can be well simulated by the simulator of the present invention.
Description
technical field [0001] The invention relates to the technical field of intelligent well completion, in particular to a production fluid simulator of an intelligent well completion simulation system. Background technique [0002] Intelligent well completion technology is an international cutting-edge technology that has only been developed in the field of petroleum engineering in the past ten years. It consists of a real-time monitoring system, data transmission system and production fluid control system installed in oil and gas production wells or injection wells to obtain downhole oil and gas production information (such as pressure, temperature, flow). Intelligent well completion technology can perform real-time reservoir management, downhole production information collection and transmission, real-time analysis of downhole occurrence and reservoir occurrence, and obtain overall completion string production data without manual intervention. Compared with conventional well...
