【摘要】：研究区探明储量是在不同时期、不同体制下按不同规范计算并上报的,其上报条件和拥有资料不尽相同,同时受原始资料录取程度、分析和认识程度等的限制,计算出的地质储量不可避免地会存在偏差。因此,对研究区石油天然气探明储量进行复算重算,分析储量变化的类型及影响因素,可以进一步掌握油田动、静态情况,实事求是地反映探明储量现状。这不仅可以为本研究区油田开发提供可靠的储量依据,同时对其他凹陷的地质储量研究也具有指导意义。本次研究根据地质储量的计算方法,开展地质储量影响参数研究,重点对含油面积、有效厚度的取值进行研究,并采用量化比较的方法,分析这些参数对地质储量的影响程度。通过对研究区基础资料进行认真整理,分析地质储量变动的原因及类型,针对饶阳凹陷油藏评价阶段探明储量计算出现偏差的区块(单元),通过对比储量复算前后各项储量参数的变化,分析各项储量参数变化对储量变化影响的大小,确定造成储量偏差的主要参数,进一步分析造成该参数发生偏差的主要影响因素,确定造成探明储量变化的主要因素。同时选取研究区内的一些典型油藏,对造成油藏评价阶段探明储量计算偏差的主要因素分别进行了进一步的解剖。通过研究总结出:地震资料品质高低,会对构造精准程度造成影响,能直接引起储量计算参数中含油面积的变化,导致储量计算结果发生重大偏差;井控程度的高低,也是评价油气藏储量计算结果可靠程度的重要指标;油藏特征认识偏差同样会引起储量计算失误,而且是评价阶段比较容易发生的一种问题;同时基础资料的多少也会影响地质储量的计算精确度。
[Abstract]:The proven reserves in the study area are calculated and reported according to different norms in different periods and systems, and their reporting conditions and possession data are different. At the same time, they are restricted by the degree of admission, analysis and understanding of the original data, etc. The calculated geological reserves are inevitably biased. Therefore, if the proven reserves of oil and gas in the study area are recalculated, the types of reserve changes and their influencing factors can be analyzed, the dynamic and static conditions of oil fields can be further grasped, and the present situation of proven reserves can be reflected realistically. This can not only provide reliable reserve basis for oilfield development in this research area, but also guide the study of geological reserves in other sag. According to the calculation method of geological reserves, the research on the influence parameters of geological reserves is carried out in this study, with the emphasis on the study of the value of oil-bearing area and effective thickness, and the quantitative comparison method is used to analyze the influence of these parameters on the geological reserves. By carefully sorting out the basic data of the study area, the causes and types of the change of geological reserves are analyzed. In view of the block (unit) in which the proven reserve calculation appears deviation in the evaluation stage of the reservoir in Raoyang sag, by comparing the changes of the reserve parameters before and after reserve recalculation, the influence of each reserve parameter on the reserve change is analyzed. The main parameters causing reserve deviation are determined, and the main influencing factors which cause the deviation of reserves are further analyzed, and the main factors that cause the change of proven reserves are determined. At the same time, some typical reservoirs in the study area are selected, and the main factors causing the deviation of proven reserves in reservoir evaluation stage are further dissected. It is concluded from the study that the quality of seismic data will affect the accuracy of the structure, which can directly cause the change of the oil-bearing area in the reserve calculation parameters, and lead to the significant deviation of the reserve calculation result, the level of well control, the degree of well control, It is also an important index to evaluate the reliability of reservoir reserves calculation results. At the same time, the amount of basic data will also affect the accuracy of geological reserves calculation.
