方法利用井温剖面监测、TPS-9000型吸汽剖面监测、产液剖面监测及剩余油监测等技术,研究新疆浅层稠油油藏纵向动用程度。目的为该类油藏的开发调整提供依据。结果井筒附近油层以中、上部动用为主,其动用程度为30%~87%;并间油层除上部动用外,底部也被热水驱扫,其动用程度为32%~50%。结论上述监测技术适于浅层稠油油藏纵向动用程度监测,其中,TPS-9000型吸汽剖面测试技术效果最好;油层纵向动用程度主要受油层物性及汽水重力分异作用的影响。
Methods Using the techniques of well temperature profile monitoring, TPS-9000 suction profile monitoring, production profile monitoring and remaining oil monitoring, the vertical utilization of shallow heavy oil reservoirs in Xinjiang was studied. The purpose of this type of reservoir development and adjustment provide the basis. As a result, the oil layer near the wellbore was mainly used in the middle and upper parts, and the degree of utilization was 30% -87%. Besides the upper part, the bottom of the oil reservoir was also swept by hot water, and its utilization rate was 32% -50%. Conclusion The above monitoring technique is suitable for the monitoring of vertical utilization of shallow heavy oil reservoirs. Among them, the TPS-9000 is the best for the test of suction profile. The longitudinal utilization of the reservoir is mainly affected by the physical property of the reservoir and gravity difference of the soft drinks.
