大牛地气田自2012年水平井大规模开发以来,水平井的井数和产量贡献逐年增加,产量贡献接近气田产出的一半,多采用分段压裂方式,但各段的产量的贡献特征不明,亟需研究。通过现场测试,掌握了选井条件和测试工艺,初步明确了各段的产量贡献特征,为下一步水平井的大规模测试及开发调整奠定了基础。 Since the large-scale development of horizontal wells in the Daniudi Gas Field in recent years, the contribution of horizontal wells has been increasing year by year with contribution of nearly half of the output of the gas fields. The multi-fracturing method is used. However, the contribution of yield Unknown, urgent research. Through on-site testing, mastered the well selection conditions and testing process, and initially identified the yield contribution characteristics of each section, which laid the foundation for the next large-scale horizontal well testing and development adjustment.
