压裂、焖井、返排及生产是页岩气开发的一个流程。压后形成SRV区域，SRV区域内的渗透率、孔隙度、裂缝规模及平均圧力等是页岩气优化焖井时间及合理配产的关键。页岩气在闷井时间优化及合理配产方面，目前没有形成定量的计算方法。

软件能够对水平井多段压裂和直井多层压裂进行压裂效果评估及焖井返排制度优化，定量给出页岩气焖井时间优化及合理配产。

选择井筒类型：选择水平井多段压裂和垂直井多层压裂两种井筒类型。

导入数据：批量导入井多个压裂段的原始压力、孔隙度、入地液量、渗透率、裂缝半长、水平井段长和裂缝条数地层数据，手动添加一个新的压裂解释段，以及读取“压裂停泵数据分析软件V2.0”中解释结果。

计算压力：对压裂井焖井阶段和返排阶段井底压力数据进行计算，查看井底流压随时间变化图。

查看地层压力分布：查看焖井阶段和返排阶段的地层压力分布形态的二维和三维示意图。

动画播放：对焖井阶段和返排阶段地层压力分布情况，根据时间步向前/向后查看图形和自动播放动画演示。

The warning of drilling engineering accidents is a long and continuous process. The sight changes of key parameters are often the precursors of accidents, so it is necessary to capture the changes of real-time parameters efficiently, accurately, carefully and quickly, and to analyze the changing trend of various parameters and the dynamic probability of engineering accidents in real time. The software is suitable for automatic warning of single well and multi-well, and can realize the functions of real-time acquisition of field data, alarm information storage, automatic alarm and alarm viewing.

Establish the judgment model of logging abnormal working condition: Investigating the research data from domestic and abroad with the experienced engineers of the logging companies, collecting the abnormal and accident cases of the drilling engineering, analyzing the engineering accidents by combining the engineering theory, sorting out and concluding the performance characteristics, and establishing engineering abnormality and accident analysis judgment model.

Establish automatic warning inference rule: According to the established engineering anomaly judgment model, select the key monitoring parameters, set the upper and lower thresholds of the parameters, the drilling state, and establish the automatic alarm judgment rule through the flexible logic relation and the weight  coefficient.
