摘要

摘要: 开发概念方案是圈闭资源经济评价中的关键环节，其设计方法基本成熟，如何科学合理确定概念方案参数是圈闭资源评价的核心问题。因圈闭资源评价阶段地质基础参数较少，不能满足通常意义下的开发方案设计要求，所以概念开发方案的编制主要依据统计类比同地区、同类已开发油气藏资料，或靠经验赋值，在多目标评价中工作量大、偏差大，影响评价结果可靠性。通过油气圈闭地质参数与开发概念方案指标关系研究，构建了概念方案中采油速度、井网密度及产量递减率3大关键参数的预测模型和模型参数的具体确定方法。选择2个典型实例——胜坨永559南和埕北313南古生界潜山圈闭进行了应用测算，计算结果与生产实践认识比较吻合。该关键参数确定方法针对我国东部砂岩油气藏具有较好的实用性，而对于西部碳酸盐岩缝洞型油藏，由于储层渗流特性差异大，适用性相对不足，有待深化研究。

Abstract: Conceptual development scheme is the key in the economic evaluation of trap. Its design method is basically mature. How to scientifically and reasonably determine the conceptual scheme parameters is the core issue. Due to limited geological parameters in the economic evaluation of trap, it can not meet the design requirements of a development plan in the usual sense. Therefore, the conceptual development scheme is mainly based on the statistical analogy of similar developed areas or similar developed oil and gas reservoirs, or by empirical evaluation. In various target evaluation, the workload is large and the deviation is obvious, which affects the reliability of evaluation result. The prediction models and parameters for three key parameters including oil production rate, well pattern density and production decline rate in the conceptual scheme were established based on the study of the relationship between geological trapping parameters of oil and gas and the conceptual development scheme. Two typical examples were selected, namely, Shengtuoyong 559 South and Chengbei 313 South Paleozoic buried hill traps for application calculation. The calculation results are in good agreement with production practice. This key parameter determination method has good practicability for sandstone oil and gas reservoirs in East China. However, for the western carbonate fractured-and-vuggy reservoirs, due to the large difference in reservoir seepage characteristics, the applicability is relatively insufficient and needs to be further studied.
