摘要/Abstract

摘要： 克拉玛依百口泉油田百重七区稠油油藏实施蒸汽吞吐开发的第二轮后,暴露出单井产油量递减快,油温下降快,周期生产时间短,产油量低,油井汽窜、出砂、套管损伤严重,油井周期回采水率低、初期油汽比低于0.2,开发效果不理想等问题。在对下侏罗统八道湾组和中三叠统上克拉玛依组疏松砂岩储集层基本特征认识的基础上,系统阐述了稠油冷采出砂的机理与影响因素,并与研究区油藏条件进行对比分析,指出百重七区稠油油藏实施出砂冷采具有较大的潜力,目前的开发阶段是出砂冷采较有利的时机。

Abstract: The heavy oil reservoir of District Baizhong-7 W ell in Baikouquan oilfield is in the second cycle of development by steam stimulation process with 3 148x10⁴t of OOIP. However, the response from steam stimulation in a single well has shown unsatisfactory efficiencies such as faster decline of production, quick decrease of in-situ oil temperature, short duration of cyclic production with low recovery rate, serious steam breakthrough, sand inflow and casing damage of producer, low cyclic water recovery rate, and early steam/oil ratio of lower than 0.2. Based on comprehensive analysis of the basic features of unconsolidated sandstone reservoirs in Badaowan formation and Upper Karamay formation, this paper systematically addresses the mechanism and afected factors for sand inflow by heavy oil cold flow production process, and compares with reservoir conditions of studied area. The results show that for this heavy oil reservoir in District Baizhong-7 Well, cold flow production with sand inflow will be carried out, which is of relatively great potentials, and current development stage will be a favorable opportunity for implementation of the cold flow production with sand inflow.

Key words: Baikouquan oilfield, heavy oil, sand production, cold flow production, steam drive
