本文選題：探明儲量 + 儲量復算重算��； 參考：《東北石油大學》2017年碩士論文

【摘要】：研究區(qū)探明儲量是在不同時期、不同體制下按不同規(guī)范計算并上報的,其上報條件和擁有資料不盡相同,同時受原始資料錄取程度、分析和認識程度等的限制,計算出的地質(zhì)儲量不可避免地會存在偏差。因此,對研究區(qū)石油天然氣探明儲量進行復算重算,分析儲量變化的類型及影響因素,可以進一步掌握油田動、靜態(tài)情況,實事求是地反映探明儲量現(xiàn)狀。這不僅可以為本研究區(qū)油田開發(fā)提供可靠的儲量依據(jù),同時對其他凹陷的地質(zhì)儲量研究也具有指導意義。本次研究根據(jù)地質(zhì)儲量的計算方法,開展地質(zhì)儲量影響參數(shù)研究,重點對含油面積、有效厚度的取值進行研究,并采用量化比較的方法,分析這些參數(shù)對地質(zhì)儲量的影響程度。通過對研究區(qū)基礎(chǔ)資料進行認真整理,分析地質(zhì)儲量變動的原因及類型,針對饒陽凹陷油藏評價階段探明儲量計算出現(xiàn)偏差的區(qū)塊(單元),通過對比儲量復算前后各項儲量參數(shù)的變化,分析各項儲量參數(shù)變化對儲量變化影響的大小,確定造成儲量偏差的主要參數(shù),進一步分析造成該參數(shù)發(fā)生偏差的主要影響因素,確定造成探明儲量變化的主要因素。同時選取研究區(qū)內(nèi)的一些典型油藏,對造成油藏評價階段探明儲量計算偏差的主要因素分別進行了進一步的解剖。通過研究總結(jié)出:地震資料品質(zhì)高低,會對構(gòu)造精準程度造成影響,能直接引起儲量計算參數(shù)中含油面積的變化,導致儲量計算結(jié)果發(fā)生重大偏差;井控程度的高低,也是評價油氣藏儲量計算結(jié)果可靠程度的重要指標;油藏特征認識偏差同樣會引起儲量計算失誤,而且是評價階段比較容易發(fā)生的一種問題;同時基礎(chǔ)資料的多少也會影響地質(zhì)儲量的計算精確度。
[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.
