7月13日从中原油田普光分公司获悉，该公司通南巴区块“马301-3井”日前顺利实现一次投产成功，日产天然气5.4万立方米。

On July 13th, it was learned from the Puguang Branch of the Middle Oilfield that the "Ma 301-3 Well" in the Tongnanba area of the company successfully achieved its first production on the 13th, with a daily output of 54,000 cubic meters of natural gas.

该井的成功投产证实了大斜度定向井高效开发深层致密砂岩气藏技术的可行性，标志着气藏评价技术从“储层+裂缝”向“优质储层+规模缝网”的迭代升级，为通南巴区块天然气高效开发提供有力技术支撑。

The successful commissioning of this well has verified the feasibility of the technology for efficiently developing deep tight sandstone gas reservoirs through highly deviated directional wells. This marks an iterative upgrade of gas reservoir eva luation technology from "reservoir + fractures" to "high-quality reservoir + large-scale fracture network", providing strong technical support for the efficient development of natural gas in the Tongnanba block.

马301-3井位于四川省巴中市，是依托构造精细解释、储层预测和裂缝预测关键技术，科学部署在马3井东北部三靶点的定向开发井，其靶点均优选断背斜高点及背冲构造，锁定油气富集有利构造区。

Well M301-3 is located in Bazhong City, Sichuan Province. It is a directional development well scientifically deployed in three target points to the northeast of Well M3, based on the key technologies of detailed structural interpretation, reservoir prediction and fracture prediction. The targets are all selected from the high points of anticlines and back-tilted structures, and the favorable structural areas with abundant oil and gas reserves are locked.

中原油田普光分公司运用纵横波速度比与阻抗双参数叠前预测，精细刻画各层系优质储层展布;采用多属性融合开展多尺度裂缝预测，多因素叠合落实有利区。

The Puguang Branch of Zhongyuan Oilfield has employed the pre-stack prediction method based on the ratio of cross-wave and longitudinal-wave velocities as well as impedance parameters to precisely delineate the distribution of high-quality reservoir layers in each stratum; it has also adopted multi-attribute fusion to conduct multi-scale fracture prediction and combined multiple factors to identify favorable areas.

为加快产能释放，中原油田普光分公司通南巴项目部坚持地质工程一体化融合，以地质认识为基础，建立单井地质知识库，持续优化压裂分段及工艺参数，助力该井一次投产成功。

To accelerate the release of production capacity, the Tongnanba Project Department of the Puguang Branch of Zhongyuan Oilfield has adhered to the integration of geology and engineering. Based on geological understanding, a single-well geological knowledge base was established, and the fracturing stages and process parameters were continuously optimized to help this well achieve a successful first production.
