China Petroleum & Chemical News Network reported recently that the Southwest Oil and Gas Production Plant used the "pre-acid + resistance-reducing water + glue" composite transformation process in the Yuanlu 15 well to achieve large-scale fracturing of the Xusan reservoir in the Yuanba gas field and obtain daily gas production.
The terrestrial Xusan reservoir of this well is located in the main channel of Yuanba 224, and its lithology is mainly sandy conglomerate with calcareous sandstone
The successful implementation of the composite transformation process provides a new choice for the potential tapping technology of the land facies old wells
