摘要:

旅大27-2油田稠油油藏采用蒸汽吞吐的方式进行热采开发。在开发过程中,影响采出液黏度变化的主要因素有:稠油族组成、温度、含水率和产液速度。首先通过室内实验研究影响旅大27-2油田稠油黏度变化的影响因素。然后结合采油井井筒数据建立旅大27-2油田稠油油藏流体流动性模型。最后根据蒸汽吞吐参数和生产数据建立稠油油藏井底流温图版以及稠油油藏采出液黏度图版。根据建立的井底流温图版,可以计算出旅大27-2油田稠油蒸汽吞吐不同阶段采出液井底流温和相应的地层温度;结合采出液黏度图版,可以计算出不同流动阶段、蒸汽吞吐不同时期采出液黏度,为油田生产以及措施实施提供指导。

Abstract:

The thermal recovery development method adopted in the heavy oil reservoir of LD-27-2 oilfield is cycle steam stimulation. In the development process, the main factors affecting the viscosity change of the production fluid were heavy oil group composition, temperature, water content and liquid production rate. Firstly, the influencing factors affecting the viscosity change of heavy oil in LD-27-2 oilfield were studied through laboratory experiments. Then, the fluidity model of the heavy oil reservoir in the LD-27-2 oilfield was established in combination with the wellbore data of the production well. Finally, based on the cycle steam stimulation parameters and production data, the bottom-hole flow temperature chart of the heavy oil reservoir and the viscosity chart of theproduction fluid of the heavy oil reservoir were established. According to the established bottom-hole flow temperature chart, the bottom fluid temperature and corresponding formation temperature of the production fluid in different stages of heavy oil steam stimulation in the LD-27-2 oilfield could be calculated. Combined with the viscosity chart of the production fluid, the viscosity of the production fluid in different flow stages and steam stimulation stages could be calculated, which could provide a guidance for oilfield production and implementation of measures.

Key words: heavy oil, LD-27-2 oilfield, flow characteristics, production fluid, chart
