二连油田稠油油藏埋藏浅、储层物性较差、储层非均质性严重，单层厚度小（平均２．２ｍ），采用小井距注蒸汽吞吐开采，在经济上和技术上存在很大的风险性。以吉３２热采试验区的开发实践为基础，分析了其注蒸汽吞吐开采特点，研究了影响吞吐效果的因素，提出适合薄油层稠油热采的厚度筛选标准及注汽参数，并对其开采效果进行了技术经济评价。结果表明：虽然试验区油层物性条件较差，但只要针对油藏特点、采取有效措施，高寒地区的稠油热采不但技术上可以取得成功，经济上也是可行的。根据试验区注汽井间干扰严重的特点，利用干扰剔除法对井间干扰效果进行了客观、真实的评价。吉３２试验区热采开发的成功，不但为高效、科学开发二连油田的稠油资源打下了基础，其开发经验对国内同类型稠油油藏的开发同样具有指导意义。图４（郭海莉摘） The heavy oil reservoirs in Erlian Oilfield are shallow buried with poor reservoir physical properties, serious reservoir heterogeneity and small single-layer thickness (average 2.2m). Economically and technically, Great risk. Based on the development practice of Ji32 32 thermal stimulation test area, the characteristics of steam injection hunt were analyzed, the factors influencing huff and puff throughput were studied, the thickness selection criteria and steam injection parameters suitable for heavy oil thermal recovery in thin oil reservoir were proposed, Mining effectiveness of the technical and economic evaluation. The results show that although the physical properties of the oil zone in the experimental area are poor, as long as effective measures are taken according to the characteristics of the reservoir, the thermal recovery of heavy oil in the alpine region is not only technically successful but also economically viable. According to the serious inter-well interference of steam injection in the pilot area, an objective and true evaluation was made on the effect of inter-well interference using the method of interference elimination. The successful development of thermal recovery in Jiji 32 pilot area not only laid the foundation for the efficient and scientific development of heavy oil resources in Erlian Oilfield, but also its development experience is also instructive for the development of similar heavy oil reservoirs in China.
