| 中文摘要: |
| 为了提高低渗油田的产能,促进页岩油及煤层气的开发,需清楚地知道压裂裂缝实时发育情况,为后续压裂设计和施工提供技术支撑。本文结合充电法、伪随机信号基本理论,从理论方法、装备研究、应用测试3个主要方面对基于an伪随机信号的分布式油气压裂监测系统及其应用进行了阐述。应用测试表明,该系统具有效率高、成本低、施工方便等特点,能够有效监测压裂裂缝基本形态,并能够计算压裂裂缝相关参数。研究成果可有效指导压裂施工工艺调整、压裂施工效果评估,从而达到油气开采过程提质增产的目的。 |
| 英文摘要: |
| In order to improve the productivity of low-permeability oil fields, the development of shale oil and coalbed methaneclearly know the real-time development of fracturing fractures, and provide technical support for subsequent fracturing design and construction. The article combines the charging method and the basic theory of pseudo-random signals. The theoretical method, equipment research, and application test describe the distributed oil gas fracturing monitoring system based on an pseudo-random signal and its application. The application test shows that the system has the characteristics of high efficiency, low cost and convenient construction. It can effectively monitor the basic morphology of fractured fractures, calculate the related parameters of fractured fractures, and effectively guide the adjustment of fracturing construction technology and the evaluation of fracturing construction effect, so as to achieve the purpose of improving the quality and production of oil and gas extraction process. The system has the characteristics of high efficiency, low cost and convenient construction. |
