An Exploration of Drainage of Beam Pumper in Sulige Gas Field

The Su 43 area is a low porosity, low permeability, low pressure, and low saturation tight gas reservoir with significant reservoir differences, complex gas water distribution, and frequent issues such as low gas water production after compression. According to initial production data, the water production rate is high, reaching 6:1 (m3/104 m3). How to avoid flooding and maintain efficient development of gas reservoirs is a key issue. This article combines the production characteristics of gas wells in Block Su 43 to carry out automatic data collection of plunger systems, online analysis of wellbore fluid accumulation, and adaptive optimization and adjustment of operating systems to improve the effectiveness of intelligent plunger gas lift. By analyzing the relationship between water and gas recovery rates, and under long-term stable production conditions, controlling a reasonable working liquid level, and using the collected bottom hole pressure and liquid level data, iterative algorithms are used to deeply correlate and calculate the optimal plunger operating system. The production system can be automatically generated, diagnosed, and corrected. After on-site testing, the feasibility of beam pumping unit drainage has been fully proven, providing a new approach for large-scale development in the Su 43 area.
