【摘要】：我國(guó)大部分油田已經(jīng)進(jìn)入了高含水、高采出程度的階段,特別是已經(jīng)開(kāi)發(fā)了四十多年的大慶油田喇嘛甸地區(qū)目前平均含水已經(jīng)超過(guò)了90%,因此研究剩余油的分布規(guī)律對(duì)油田的進(jìn)一步開(kāi)發(fā)與調(diào)整具有重要意義。本文以高分辨率層序地層學(xué)和儲(chǔ)層沉積學(xué)為指導(dǎo),對(duì)喇嘛甸油田喇北東塊L8-JP182井區(qū)高II1-18小層進(jìn)行了系統(tǒng)的高頻等時(shí)層序地層劃分對(duì)比,將目的層劃分為1個(gè)長(zhǎng)期基準(zhǔn)面旋回、3個(gè)中期基準(zhǔn)面旋回和8個(gè)短期基準(zhǔn)面旋回。在此基礎(chǔ)上對(duì)目的層的沉積微相進(jìn)行了劃分和識(shí)別,對(duì)三角洲前緣亞相的砂體形態(tài)、分布情況進(jìn)行了系統(tǒng)研究,建立了一整套密井網(wǎng)測(cè)井曲線(xiàn)沉積微相識(shí)別方法,共識(shí)別出水下分流河道、主體席狀砂、非主體席狀砂、河口砂壩和水下分流河道間5個(gè)微相。在精細(xì)的地層劃分對(duì)比和沉積微相研究基礎(chǔ)上,對(duì)儲(chǔ)層的非均質(zhì)性進(jìn)行了系統(tǒng)的分析,總結(jié)了儲(chǔ)層的平面非均質(zhì)性、縱向非均質(zhì)性和層間非均質(zhì)性特征、分布以及影響因素,為剩余油分布規(guī)律及主控因素研究奠定了基礎(chǔ)。綜合運(yùn)用巖心、測(cè)井、生產(chǎn)動(dòng)態(tài)等資料,結(jié)合層序地層學(xué)、沉積微相、儲(chǔ)層非均質(zhì)性等的研究,從宏觀(guān)分布的角度總結(jié)了研究區(qū)平面和垂向的7種剩余油類(lèi)型,分析了沉積微相、微構(gòu)造和儲(chǔ)層非均質(zhì)性對(duì)剩余油的控制作用,以及各個(gè)小層的剩余油平面和縱向的剩余油分布影響因素。在剩余油類(lèi)型及主控因素分析的基礎(chǔ)上,對(duì)L8-JP182井區(qū)高II1-18小層的剩余油的分布規(guī)律進(jìn)行了系統(tǒng)分析,認(rèn)為平面上剩余油的富集主要受沉積微相和儲(chǔ)層非均質(zhì)性的控制,縱向上可以分為頂部富集型、均勻驅(qū)替型和底部富集型3種富集規(guī)律。
[Abstract]:Most oil fields in China have entered the stage of high water cut and high recovery. Especially, the average water cut in Lamadian area of Daqing Oilfield, which has been developed for more than 40 years, has exceeded 90 percent, so it is of great significance to study the distribution law of remaining oil for further development and adjustment of oil field. Guided by high resolution sequence stratigraphy and reservoir sedimentology, this paper makes systematic high frequency isochronous sequence stratigraphic classification and correlation of high II1-18 stratigraphy in L8-JP182 well area of Lamadian Oilfield. The target layer is divided into 1 long term datum cycle, 3 mid term datum cycle and 8 short term datum cycle. On this basis, the sedimentary microfacies of the target layer are divided and identified. The sand body morphology and distribution of the delta front subfacies are systematically studied, and a set of methods for identifying sedimentary microfacies of the dense well logging curve are established. There are five microfacies between underwater distributary channel, main sheet sand, non-main sheet sand, estuary bar and underwater distributary channel. On the basis of fine stratigraphic division and correlation and study of sedimentary microfacies, the reservoir heterogeneity is systematically analyzed, and the characteristics, distribution and influence factors of reservoir plane heterogeneity, longitudinal heterogeneity and interlayer heterogeneity are summarized. It lays a foundation for the study of residual oil distribution law and main controlling factors. Based on the data of core, logging and production performance, combined with the study of sequence stratigraphy, sedimentary microfacies and reservoir heterogeneity, seven types of remaining oil in the plane and vertical direction of the study area are summarized from the point of view of macroscopic distribution. The controlling effects of sedimentary microfacies, microstructures and reservoir heterogeneity on residual oil, and the factors affecting the distribution of residual oil in each sublayer in plane and longitudinally are analyzed. Based on the analysis of residual oil types and main controlling factors, the distribution law of residual oil in high II1-18 layers in L8-JP182 well area is systematically analyzed. It is considered that the enrichment of residual oil on the plane is mainly controlled by sedimentary microfacies and reservoir heterogeneity. Vertically, there are three types of enrichment: top enrichment, homogeneous displacement and bottom enrichment.
