丫角油田稠油油藏热采实践与认识

丫角油田稠油油藏油层薄、物性差,原油粘度高。通过优选相关参数进行热采试验后认为,现有蒸汽吞吐热采工艺技术,能满足丫角油田稠油油藏开采技术要求。但从开采效益方面分析,在现有的技术经济条件下,对丫角油田稠油油藏进行热采开发,经济效益较差。

Thermal Recovery of Heavy Oil Reservoir in Yajiao Oilfield

Heavy oil reservoir in Yajiao Oilfield features thin oil layers, bad physical properties and high crude viscosity. Thermal recovery test based on optimized relevant parameters proves that existing huff--puff thermal recovery technology is qualified for production of Yajiao heavy oil reservoir. Considering from production benefit, however, it is improper to implement thermal--recovery--based development under conditions of existing technology and economy.
