摘要/Abstract

摘要： 以风城油田浅层超稠油油藏双水平井蒸汽辅助重力泄油（SAGD）先导试验为例，结合跟踪数值模拟研究，依据蒸汽腔操作压力、采注比和蒸汽腔发育特征，将双水平井蒸汽辅助重力泄油启动阶段和生产阶段细分为均匀等压循环、均衡增压循环、转SAGD生产初期、高压生产、稳定生产和衰竭生产等6个阶段，并提出各阶段的转换条件。根据风城油田双水平井蒸汽辅助重力泄油生产实践，对各阶段关键参数进行了优化，可作为同类油藏双水平井蒸汽辅助重力泄油生产方式的技术参考。

Abstract: Taking the shallow super?heavy oil reservoir in Fengcheng oilfield developed by dual?horizontal well SAGD (steam assisted gravity drainage) process in pilot test area as an example, combined with tracking numerical simulation, in accordance with the characteristics of steam chamber operating pressure，production?injection ratio and development characteristics of steam chamber, the starting stage and production stage of the SAGD are subdivided into such six stages as uniform?pressure heat circulation, balanced pressurization heat circulation, early stage of switching to SAGD, SAGD production at high?pressure, SAGD stable production and SAGD depletion production, and the conditions of each stage conversion are proposed. According to the production performance of the dual?horizontal well SAGD pilot test area, the injection?production parameters at each stage are optimized, which could be served as technical references for the dual?horizontal well SAGD in similar reservoirs
