欢60区块油田开发设计方案.docVIP

摘 要 以辽河油田欢60区块为研究对象，通过测井资料及开发动态资料的统计分析,对辽河油田欢60从宏观到微观、从定性到定量进行了详细研究。 辽河油田欢60区块油层沉积相为三角洲前缘亚相,与已开发区块对比,主要的储层微相为前缘薄层席状砂。鉴于开发层系,开发方式的原因该区块采用直排井注水开采。 本文首先进行了油藏非均质评价这主要是把特征相近的油层合在一起，用一套生产井网单独开采，然后对其进行了地质储量的计算，这是石油开采之前最重要的一环，我们必须明确其总量以对其开采量进行分析，之后我们进行了井数的计算包括井距排距的计算都一一做了合理的评价，然后进行见水前和见水后开发指标的计算确定其见水时间，在此基础上进行经济评价，经济评价从其产量入手根据国民经济发展战略和石油工业中的长期规划，在资源评价、工程评价、技术评价和市场预测的基础上计算其开发成本及产出效益以做到经济透明。 关键词：测井，开发层系，井网，经济评价 Abstract Huan 60 block in Liaohe Oilfield as the research object,through statistical analysis of data and the dynamic development data logging in Liaohe Oilfield,Huan 60 from macro to micro,from qualitative analysis to quantitative analysis are studied in detail.Huan 60 block of Liaohe Oilfield reservoir sedimentary facies is delta front subfacies,and developed blocks have been compared,the main reservoir microfacies for frontal thin sand sheet. First, this paper make a Heterogeneity evaluation that Liaohe Oilfield Huan60 blocks the purpose is make the reservoir in the together that they characteristics it’s similar, they are mined by a series of production well pattern, then carried out the calculation of geological reserves, it’s important that in oil exploration, We must be clear about its total and we could analyze their exploitation, and we carried out the calculation about the number of wells, than we carried out the calculation of see the water and the time of see the water, on this basis, we make the economic evaluation, economic evaluation from its yield to start economic evaluation based on national economic development strategy and the oil industry in the long-term planning,in resource evaluation,project evaluation,technology assessment and market forecasts,carried out the calculation of development costs and output efficiency, make the economic transparent. Key words:Logging,development layer series,well pattern,economic evaluation. 目 录 前 言 1 第1章 基础数据资料 2 1.1 油区概况 2 1.2 油藏几何参数及各小层物性 2 1.3 地层水矿物质 3 1.4 油水相渗关系数据 3 1.5 井眼半径 4 1.6 油水井操作条件 4 1.7 常用
