The four internal gas reservoirs of the Aurora series lamp have obtained another million cubic meters of high-yield wells

On September 14, PetroChina Southwest Oil & Gas Field Company's rolling exploration and development well Gaoshi 103-C1 test obtained an unobstructed flow rate of 1,577,200 cubic meters/day of high-yield gas flow. This well is the third million-square-meter gas well in the Sinian Deng-4 gas well, which marks an important progress in the rolling evaluation of karst gas reservoirs in low-quality thin reservoirs in the Taipei, and further strengthens the confidence in the large-scale and cost-effective development of the Deng-4 gas reservoir in the Tainei system.

The four gas reservoirs of the Aurora system lamp

The production capacity of a single well in the four gas reservoirs in the four Aurora series lamps is low as a whole, and the difference is large, and it is difficult to develop economies of scale. Through the establishment of a research team, focusing on the technical bottleneck of high yield and stable production, the fine description technology of high-quality reservoirs under the background of thin hills and beaches and weak karst in the platform was formed, the division standard of high-quality reservoirs to control production capacity was clarified, the characteristic technology of fine carving of high-quality thin karst reservoirs in the platform was formed, and the high-yield well model of the Dengsi gas reservoir in the platform was established.

In order to implement the requirements of "quality improvement, efficiency improvement, and efficiency improvement", the company drives rolling evaluation with scientific and technological innovation, improves the efficiency of gas field development, combines geology and seismic, carries out comprehensive evaluation of blocks, demonstration of well location targets, selects Gaoshi 103 well to carry out sidetracking, evaluates the development mode of high-quality reservoirs and improves the technical ability of single well production. The daily gas production was 1,017,800 cubic meters and the unobstructed flow rate was 1,577,200 cubic meters per day, and the production of a single well was increased by 7 times, and good development results were achieved.
