返排 meaning in Chinese
flowback
Examples
- To ascertain how to produce differential pressure reasonably during the course of high temperature and pressure gas well testing , we must consider synthetically the following situations : both liquid in well bore and solid phase particles of mud in strata can be carried out through airflow ; we must avoid sand production out of borehole walls and make the selected differential pressure meet the demands of the testing instrument capability ; the calculation of differential pressure when no sand comes out of strata covers the calculation of strength of rock of borehole walls and airflow velocity , etc
摘要高温高压气井测试中合理生产压差的确定需要综合考虑使气流能够在井筒中携液、返排侵入地层中的泥浆固相颗粒、避免井壁出砂、满足测试工具性能要求等；地层不出砂压差计算还涉及到井壁岩石的强度计算、气流流速计算等。 - Aiming at characteristics of serious conflict among layers , thin layers developed and scattered distribution of remaining oil , this paper introduces techniques of non - gel fracturing , multi - fractures fracturing , large discharge capacity and large sand amount fracturing , thin layer fracturing and high effective return discharge
摘要针对大庆油田萨南开发区三类油层层间矛盾突出、油层发育薄及剩余油分布零散等特点，根据油藏精细地质研究成果，通过个性化压裂设计，在试验区三类油层聚驱挖潜过程中，应用了非凝胶压裂、多裂缝压裂、大排量及大砂量压裂、薄隔层压裂以及高效返排压裂等配套的工艺技术。
