【摘要】：國內(nèi)外各大油田經(jīng)過十多年的注水開發(fā),大都進入高含水,高采出程度階段。我國老油田已經(jīng)進入高含水中后期,且新區(qū)塊地質(zhì)條件復(fù)雜、勘探難度大,如何穩(wěn)步開采老油田成為亟待解決的問題,為此有必要針對油田剩余油分布及挖潛方向進行深入研究。本論文通過對國內(nèi)外油田開發(fā)中后期剩余油分布評價方法進行梳理,依據(jù)油田開發(fā)地質(zhì)理論及姚店油田的開發(fā)現(xiàn)狀,明確了當(dāng)前油田生產(chǎn)和開發(fā)中存在的問題。在此基礎(chǔ)上,采用宏觀地質(zhì)構(gòu)造對比與微觀儲層特征分析相結(jié)合的研究方法,對區(qū)塊的資源儲量豐度、單井控制儲量進行理論計算與分析,同時標(biāo)定了各層可采儲量。最后,根據(jù)剩余油富集程度,劃分出一、二、三類潛力區(qū)域。研究結(jié)果表明:一、二類剩余油潛力區(qū)可采儲量很大,富集規(guī)模和程度集中,此部分區(qū)域是將來油田挖潛的最優(yōu)對象;第三類剩余油潛力區(qū)特點是分布面積很大,占到整個姚店區(qū)塊疊合面積的77%,但是富集程度較小,挖潛潛能較小,為該區(qū)塊后期剩余油挖潛的攻堅區(qū)域。本次剩余油潛力評價,指出了姚店油田未來的開發(fā)及挖潛方向,同時對鄂爾多斯盆地低滲透、低豐度、低飽和度及高含水油藏剩余油研究評價方法具有一定的指導(dǎo)意義。
[Abstract]:After more than ten years of water injection development, most oil fields at home and abroad have entered the stage of high water cut and high recovery. The old oil fields in our country have entered the middle and late stage of high water cut, and the geological conditions of the new block are complicated and the exploration is difficult, so how to develop the old oil fields steadily becomes an urgent problem to be solved. Therefore, it is necessary to further study the distribution of remaining oil and the direction of tapping potential. Based on the theory of oilfield development geology and the present development situation of Yaodian oilfield, the problems existing in the production and development of oil fields at present are clarified by combing the evaluation methods of remaining oil distribution in the middle and late stages of oilfield development at home and abroad. On the basis of this, using the research method of combining macroscopic geological structure correlation with microcosmic reservoir characteristic analysis, theoretical calculation and analysis of resource reserves abundance and single well controlled reserves of blocks are carried out, and recoverable reserves of each layer are calibrated at the same time. Finally, according to the degree of remaining oil enrichment, the potential regions of one, two and three types are divided. The results show that: first, the recoverable reserves of the second type remaining oil potential area are very large, the enrichment scale and degree are concentrated, this part of the area is the best object for tapping the potential oil fields in the future, and the third type remaining oil potential area is characterized by the large distribution area. It accounts for 77% of the overlap area of the whole Yao Dian block, but the enrichment degree is small and the potential of tapping potential is small, which is a key area for tapping the remaining oil potential in the late stage of the block. This evaluation of residual oil potential points out the future development and tapping direction of Yaodian Oilfield and has certain guiding significance for the research and evaluation of remaining oil in low permeability, low abundance, low saturation and high water cut reservoirs in Ordos Basin.
