中国石油网消息：3月28日，渤海钻探广西BH50130钻井队在桂融地4井施工中顺利完成取芯作业，岩芯收获率达99.7%。

China Oil News: On March 28th, the BH50130 drilling team of Bohai Drilling Company in Guangxi successfully completed the core sampling operation during the construction of the Guilongdi 4 well. The rock core recovery rate reached 99.7%.

该井是中国石油进入广西页岩气市场的首口井，此次取芯作业的圆满完成，为公司开拓广西页岩气市场奠定了坚实基础。

This well is the first one that China National Petroleum Corporation has drilled to enter the shale gas market in Guangxi. The successful completion of this coring operation has laid a solid foundation for the company to expand its shale gas market in Guangxi.

页岩气取芯作业是勘探开发的关键环节，岩芯收获率直接影响地质资料采集的精准度，对后续储量评估与开发方案制定具有重要意义。本次施工区域地质条件复杂、井下工况多变且施工标准较高，给取芯作业带来一定难度。对此，渤海钻探组织技术骨干反复研判地质资料，结合区域地层特性制定专项取芯施工方案，确保作业有序推进。

Shale gas coring operations are a crucial part of exploration and development. The yield rate of rock cores directly affects the accuracy of geological data collection and is of great significance for subsequent reserve assessment and development plan formulation. The geological conditions in the construction area this time were complex, the underground working conditions were variable, and the construction standards were high, which brought certain difficulties to the coring operation. In response to this, Bohai Drilling organized technical experts to repeatedly analyze geological data and, in combination with the regional stratum characteristics, formulated a special coring construction plan to ensure the smooth progress of the operation.

施工期间，现场管理人员全程驻守一线，推行“全过程跟踪、全时段监测、全方位协调”的“三全”工作法，实时监控井下动态与钻井参数；技术人员严格落实“精读地层、精调参数、精控工序”的“三精”操作法，针对地层波动和井下复杂情况及时调整操作，严格把控取芯、割芯、提芯等关键工序，确保岩芯的完整性与连续性。

During the construction period, the on-site management personnel were stationed at the front line throughout the process, implementing the "three-all" work method of "full-process tracking, full-time monitoring, and all-round coordination", to monitor the underground dynamics and drilling parameters in real time; the technical personnel strictly followed the "three-exact" operation method of "precise reading of the strata, precise adjustment of parameters, and precise control of procedures", promptly adjusting operations in response to stratum fluctuations and underground complex situations, strictly controlling key procedures such as coring, cutting core, and lifting core, to ensure the integrity and continuity of the rock cores.

此次取芯为广西页岩气地质研究提供了真实、完整的第一手岩芯资料，也为后续勘探开发和产能建设提供了坚实支撑。

This core extraction has provided the first-hand, genuine and complete core data for the geological research of shale gas in Guangxi, and has also offered solid support for subsequent exploration, development and capacity construction.
