【摘要】：页岩气作为一种清洁、高效的新型能源,有着非常广阔的经济前景,目前,国内页岩气开发已初具一定规模,工艺在不断成熟。国内页岩气储层具有低孔隙、特低渗透物性特征且岩层薄、埋藏较深的特点,主要开采页岩气的方法为水平井旋转导向、随钻测井(LWD)、随钻测量(MWD)以及水力泵送桥塞-射孔联作分段压裂技术,真正、有效地提高了单井产能。但是在实际现场工作中,复杂井眼轨迹作为不可避免的客观影响因素,给水力泵送带来了施工困难。介于此,本文重点对复杂井眼轨迹中的泵送阶段出现的难点进行分析,并提出合理、有效的处理措施,在降低施工风险和节约时效的同时,有效解决困扰开发生产的技术难点,为我国在页岩气开发提供有价值的参考。
[Abstract]:Shale gas, as a clean and efficient new energy source, has a very broad economic prospect. At present, the domestic shale gas development has begun to have a certain scale and the technology is continuously maturing. The domestic shale gas reservoir has low porosity. The characteristics of very low permeability, thin rock formation and deep burial. The main methods for producing shale gas are horizontal well rotation, LWD while drilling logging, MWD while drilling and fracturing with hydraulic pumping bridge plug and perforation. The productivity of single well is improved effectively. But in the actual field work, the complex well trajectory, as an inevitable objective influencing factor, brings the construction difficulty to hydraulic pumping. This paper focuses on the analysis of the difficulties in the pumping stage in the complex borehole trajectory, and puts forward reasonable and effective treatment measures, which can effectively solve the technical difficulties perplexing the development and production while reducing the construction risk and saving the time limit. It provides valuable reference for shale gas development in China.
