【摘要】：研究區(qū)探明儲(chǔ)量是在不同時(shí)期、不同體制下按不同規(guī)范計(jì)算并上報(bào)的,其上報(bào)條件和擁有資料不盡相同,同時(shí)受原始資料錄取程度、分析和認(rèn)識(shí)程度等的限制,計(jì)算出的地質(zhì)儲(chǔ)量不可避免地會(huì)存在偏差。因此,對(duì)研究區(qū)石油天然氣探明儲(chǔ)量進(jìn)行復(fù)算重算,分析儲(chǔ)量變化的類型及影響因素,可以進(jìn)一步掌握油田動(dòng)、靜態(tài)情況,實(shí)事求是地反映探明儲(chǔ)量現(xiàn)狀。這不僅可以為本研究區(qū)油田開(kāi)發(fā)提供可靠的儲(chǔ)量依據(jù),同時(shí)對(duì)其他凹陷的地質(zhì)儲(chǔ)量研究也具有指導(dǎo)意義。本次研究根據(jù)地質(zhì)儲(chǔ)量的計(jì)算方法,開(kāi)展地質(zhì)儲(chǔ)量影響參數(shù)研究,重點(diǎn)對(duì)含油面積、有效厚度的取值進(jìn)行研究,并采用量化比較的方法,分析這些參數(shù)對(duì)地質(zhì)儲(chǔ)量的影響程度。通過(guò)對(duì)研究區(qū)基礎(chǔ)資料進(jìn)行認(rèn)真整理,分析地質(zhì)儲(chǔ)量變動(dòng)的原因及類型,針對(duì)饒陽(yáng)凹陷油藏評(píng)價(jià)階段探明儲(chǔ)量計(jì)算出現(xiàn)偏差的區(qū)塊(單元),通過(guò)對(duì)比儲(chǔ)量復(fù)算前后各項(xiàng)儲(chǔ)量參數(shù)的變化,分析各項(xiàng)儲(chǔ)量參數(shù)變化對(duì)儲(chǔ)量變化影響的大小,確定造成儲(chǔ)量偏差的主要參數(shù),進(jìn)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(chǔ)量變化的主要因素。同時(shí)選取研究區(qū)內(nèi)的一些典型油藏,對(duì)造成油藏評(píng)價(jià)階段探明儲(chǔ)量計(jì)算偏差的主要因素分別進(jìn)行了進(jìn)一步的解剖。通過(guò)研究總結(jié)出:地震資料品質(zhì)高低,會(huì)對(duì)構(gòu)造精準(zhǔn)程度造成影響,能直接引起儲(chǔ)量計(jì)算參數(shù)中含油面積的變化,導(dǎo)致儲(chǔ)量計(jì)算結(jié)果發(fā)生重大偏差;井控程度的高低,也是評(píng)價(jià)油氣藏儲(chǔ)量計(jì)算結(jié)果可靠程度的重要指標(biāo);油藏特征認(rèn)識(shí)偏差同樣會(huì)引起儲(chǔ)量計(jì)算失誤,而且是評(píng)價(jià)階段比較容易發(fā)生的一種問(wèn)題;同時(shí)基礎(chǔ)資料的多少也會(huì)影響地質(zhì)儲(chǔ)量的計(jì)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.
