近日，江汉油田涪陵页岩气田焦页86号平台焦页86-Z1HF井、焦页86-7HF井完成12毫米油嘴产能测试。两口井井口压力超过20兆帕，日产气量突破20万立方米。

Recently, the Jiaoyi 86-Z1HF well and the Jiaoyi 86-7HF well on the Jiaoyi 86 platform of the Ehuang shale gas field in Jianghan Oilfield completed the production capacity test with 12-millimeter oil nozzles. The wellhead pressure of both wells exceeded 20 megapascals, and the daily gas production exceeded 200,000 cubic meters.

焦页86-Z1HF井属于中部气层的高效开发调整井，焦页86-7HF井则属于加密井。该井组埋藏深、地层坡度陡，且井与井之间容易互相干扰。

Well No. 86-Z1HF of Jiao Page belongs to the high-efficiency development adjustment well of the central gas layer, while Well No. 86-7HF of Jiao Page is an exploration well. This well group is deeply buried, with a steep stratum slope, and the wells are prone to interfere with each other.

为此，在射孔作业环节，技术人员精准把控射孔方位与孔密，主动规避高风险区域，定向引导裂缝延展方向；在压裂施工过程中，采取井段迭代、工艺动态调整模式，搭配多种粒径支撑剂，连续加砂、分段加砂，保障不同尺度裂缝有效支撑，全程实时监测邻井压力变化，按需注入暂堵剂封堵窜流通道，实现风险管控与增产提效。

Therefore, in the perforation operation stage, the technicians precisely control the perforation direction and density, actively avoid high-risk areas, and guide the extension direction of the fractures; during the fracturing construction process, they adopt the iterative well section and dynamic process adjustment mode, combine multiple particle size support materials, continuously add sand and segmentally add sand, ensure effective support for fractures of different scales, conduct real-time monitoring of pressure changes in adjacent wells, and inject temporary blocking agents as needed to seal the窜流 channels， achieving risk control and increased production and efficiency.
