Sinopec News Network News On May 12, Southwest Engineering Company conducted field application of temporary plugging and flow-limiting acid fracturing technology in Heshen 5 Well, and obtained high-yield oil and gas flow, marking the further improvement of the company's acid fracturing technology.

In order to solve the limitations of the original tool layering, fiber steering, plastic ball steering and chemical steering in the multi-layer and three-dimensional balanced transformation, and to promote the marginalization and deepening of exploration and development, Southwest Underground established a research team to conduct in-depth investigations.

This technology meets the needs of balanced three-dimensional reconstruction of reservoirs with strong longitudinal heterogeneity, and is simple to operate, strong in adaptability, and low in cost.
