摘要
压裂水平井已经成为目前开采致密气资源的主要手段。如何评价和分析油气藏压裂后的效果是油气藏工程中一个亟待解决的问题。压裂效果评价需要存储的数据种类越来越多、数据量也越来越大,为此,通过裂缝监测、产能评价、经济评价和区块综合评价等效果评价方法,结合计算机和软件技术,建立了水平井压裂效果评价数据支持系统。系统可以对井的基础数据、地层参数、压裂施工参数等数据进行录入与查询,通过等值线输出线性回归得出影响压裂效果的因素,从而评价致密气水平井的压裂效果。最后,利用大牛地气田某口水平井进行实例分析,检验了软件的稳定性以及压裂效果评价方法的可行性。
The fractured horizontal well has become the primary means of tight gas exploitation. In reservoir engineering, it is urgent to understand how to evaluate and analyze the effects of fracturing. Both types and amount of data to be stored for such evaluation are growing. Therefore, the fracture monitoring, productivity evaluation, e- conomic evaluation and comprehensive block evaluation are combined with the computer and software technology to develop a data support system for horizontal well fracturing effect evaluation. With this system, the data like well data, formation parameters and fracturing parameters can be entered and inquired. Factors affecting the fracturing effect can be obtained by contour line outputted linear regression, thereby the fracturing effect of tight gas horizontal wells can be evaluated. Finally, a case study is made to a horizontal well in Daniudi gas field to validate the stability of software and the feasibility of the fracturing effect evaluation method.
