Enhancement Mechanisms of Multi-Scale Huff-and-Puff in Horizontal Wells for Tight Sandstone Reservoirs‑A Case Study of the Chang 63 Formation in the Wuqi Block, Ordos Basin
Hydraulic fracturing is the primary method for developing tight sandstone reservoirs. In particular, horizontal well staged fracturing huff-n-puff is the main technique for enhancing oil recovery in tight sandstones. To clarify the remaining oil distribution and oil displacement mechanism under this technological backg...
