一直以来，油气工艺研究院专注于川南页岩气以及常规气储层改造技术研究，通过一系列技术创新和管理优化，为提升天然气开采效率奠定了坚实基础。在常规气开采领域，2024年年初项目团队针对嘉陵江组储层特点，开展了酸压提产技术攻关。通过对比不同区域储层的酸压施工参数，明确了影响产能的主控因素，并围绕这些因素优化酸压施工参数。通过优化了酸压工作液配方，有效降低施工成本8%以上。在吉富10井的现场应用中，该技术取得了显著效果，测试产量大幅提升。

在页岩气开采方面，项目团队持续开展水平井压裂关键参数优化工作。针对不同特征的储层，制定差异化压裂对策。针对不同套变类型，优化差异化防套变理念，形成了相应的技术做法。深化套变诱导因素的认识，初步划分了套变类型，完善了套变风险评估技术，以此为依据，现场动态识别套变风险，对于风险段及时防控，同时形成套变压窜快速处置对策，极大提高了套变后处置速度，避免等停过程中发生套变加剧。目前配置区深层页岩气已完成自205H76、自205H69两平台及自306井的压裂施工，平均加砂强度3.4吨/米，平均用液强度30方/米。

下一步，吉林油田将围绕川南配置区提高支撑缝长研究、套变压窜风险评价、茅口组酸压设计图版完善以及嘉陵江组酸压参数优化等方面开展深入研究。同时，积极筛选酸液评价岩芯和泥浆溶蚀率实验，为未来的技术应用提供有力支持，以川南天然气开采技术的不断进步推动川南天然气产业的持续尊龙凯时·(中国)人生就是搏!。

For a long time, the Oil and Gas Technology Research Institute has been focusing on the research of shale gas and conventional gas reservoir reconstruction technology in southern Sichuan, and has laid a solid foundation for improving the efficiency of natural gas extraction through a series of technological innovations and management optimization. In the field of conventional gas extraction, at the beginning of 2024, the project team carried out research on acid pressure production technology according to the characteristics of the reservoir of Jialingjiang Formation. By comparing the acid pressure construction parameters of different reservoirs in different regions, the main controlling factors affecting productivity are identified, and the acid pressure construction parameters are optimized around these factors. By optimizing the formula of acid pressing working fluid, the construction cost is reduced by more than 8%. In the field application of the Gifu 10 well, the technology has achieved remarkable results, and the test production has been greatly increased.

In shale gas production, the project team continues to optimize key parameters for horizontal well fracturing. According to different characteristics of the reservoir, develop differentiated fracturing strategies. According to different types of variation, the concept of differentiated anti-variation is optimized, and corresponding technical practices are formed. Deepen the understanding of the induction factors of the nested changes, initially classify the types of nested changes, and improve the risk assessment technology of nested changes. Based on this, the on-site dynamic identification of nested changes risks, timely prevention and control of the risk segment, and the formation of rapid disposal countermeasures of nested changes, greatly improve the disposal speed after the nested changes, and avoid the aggravation of nested changes during the waiting process. At present, the deep shale gas in the configuration area has completed the fracturing construction from 205H76 and 205H69 platforms and from 306 well, with an average sand loading intensity of 3.4 tons/meter and an average liquid used strength of 30 square meters.

In the next step, Jilin Oilfield will carry out in-depth research on improving the support joint length in the south Sichuan configuration area, risk eva luation of the transformer channeling, improvement of the acid pressure design pattern of Maokou Formation and optimization of the acid pressure parameters of Jialingjiang Formation. At the same time, actively screening acid to eva luate the core and mud dissolution rate experiment, to provide strong support for future technology application, with the continuous progress of natural gas exploitation technology in south Sichuan to promote the sustainable development of natural gas industry in south Sichuan.
