    Abstract
    普光气田水平井具有井深、射孔井段跨度大、射孔厚度大的特点，储层层间非均质性非常严重，Ⅰ类、Ⅱ类和Ⅲ类储层交错分布，部分井存在边底水。为了实现水平井段均匀布酸、提高酸化效果、稳气控水等目的，通过对水平段注酸井筒流动压力分布、吸液强度分析，确定出普光水平井投产一体化管柱的封隔器卡封段级数、滑套下入位置、滑套孔径、孔数、尾管下入深度等参数。通过理论分析和数值模拟计算，研究了普光高含硫水平井不同完井方式下的酸压（化）投产一体化管住的结构及参数优化方法，为高含硫气田水平井分段酸压（化）管柱设计提供了技术思路，提高了普光水平井的酸压（化）效果。

    • Pretraining has recently greatly promoted the development of natural language processing (NLP)
    • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
    • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
    • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
    • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
