单83块蒸汽驱开发注采参数优化研究

Optimization of Injecting and Producing Parameters of Steam Flooding Development in Block 83 of Shanjiasi Oilfield

蒸汽驱效果受油层地质条件、油藏动态状况、蒸汽驱注采参数及现场条件等因素的影响较大。针对单83块实施的4个蒸汽驱井组,在油藏静态、动态拟合的前提下,系统地进行了蒸汽驱注采比、注汽速度、生产井提液等数值模拟综合优化研究,找出了此类油藏的蒸汽驱开采规律,以及适合油藏蒸汽驱开发的一系列参数技术界限,优化出可供矿场实施的开发调整方案。

Steam flooding result is influenced by several parameters such as reservoir geological condition,reservoir dynamic condition,injecting and producing parameters on steam flooding and onsite condition. Based on the static and dynamic fitting results of the reservoir,an optimization study was performed on four well groups of the Block 83. The sensitivity analysis of injection-production ratio,injection rate and liquid lift from producing wells was performed and the development mechanism of the same reservoir and technical limits of steam flooding technology were discovered.
