【摘要】：錦33塊自1981年投產(chǎn),依靠天然能量開發(fā),開發(fā)目的層為興隆臺和熱河臺油層。受構(gòu)造和沉積環(huán)境的雙重影響,斷塊開發(fā)矛盾較為突出,興隆臺油層邊底水能量充足,已進入特高含水開發(fā)期,剩余油高度分布,挖潛難度較大;熱河臺油層受沙三段濁積體沉積特征的影響則表現(xiàn)為低產(chǎn)能。為進一步挖掘斷塊剩余油氣潛力,我們開展地層對比劃分、構(gòu)造描述、沉積相劃分與地質(zhì)、地震結(jié)合,研究油藏特征與油水分布特征。利用SeisWare解釋系統(tǒng)對相關(guān)開發(fā)區(qū)域地震資料重新進行構(gòu)造解釋,進行沉積相特征及相標志分析,儲層砂體厚度發(fā)育情況及砂體分布特征研究。結(jié)合沉積相發(fā)育、構(gòu)造斷層演化、儲層發(fā)育分布預測、成藏條件規(guī)律研究等,進行綜合地質(zhì)評價,為下步挖潛部署提供有力的技術(shù)支撐。地層對比劃分研究,資料來源于完鉆至熱河臺油層及熱河臺以下地層的錦33井區(qū)及周邊相關(guān)井的錄井及測井完井資料,研究方法是利用完井資料,結(jié)合井區(qū)沉積相特征,利用構(gòu)造發(fā)育不同部位井的完井錄井資料及相鄰井聯(lián)通的構(gòu)造剖面,建立北東南西向地層對比聯(lián)通剖面,依據(jù)沉積旋忯規(guī)律并結(jié)合地層厚度,進行相關(guān)地層的對比劃分。在采用常規(guī)的地質(zhì)研究方法之上,我們結(jié)合Landmark工作站解釋系統(tǒng),利用鉆井、錄井、測井、試油等完井資料,針對該區(qū)域沉積發(fā)育背景復雜、目的層埋深落差大、構(gòu)造特征認識不清、原地震資料精度低等困難,運用多角度研究方法對該區(qū)域地震地質(zhì)資料進行了高精度沉積構(gòu)造二次解釋。根據(jù)對該區(qū)的剩余油分布規(guī)律研究,結(jié)合綜合地質(zhì)研究的認識,提出相應配套調(diào)整部署及挖潛方案,目前已取得較好的挖潛效果。
[Abstract]:Block Jin33 has been put into production since 1981, relying on natural energy development, and the development target layer is Xinglongtai and Rehetai oil layers. Due to the dual influence of structure and sedimentary environment, the contradiction of fault block development is more prominent. Xinglongtai oil reservoir edge and bottom water energy is sufficient, has entered the extremely high water cut development period, the remaining oil height distribution, tapping potential is difficult; The depositional characteristics of turbidite in the third member of Shahetai reservoir are characterized by low productivity. In order to further exploit the residual oil and gas potential of fault block, we develop stratigraphic correlation division, structural description, sedimentary facies division and geology. Seismic combination, reservoir characteristics and oil-water distribution characteristics, using SeisWare interpretation system to reinterpret seismic data related to the development region, sedimentary facies characteristics and facies indicators analysis. Combined with the development of sedimentary facies, structural fault evolution, reservoir development distribution prediction, reservoir formation conditions and so on, comprehensive geological evaluation is carried out. The data are derived from the logging and well completion data of the Jin33 well area and the related wells in the Jin-33 area and the surrounding wells which have been drilled to the Jehetai reservoir and the formation below the Jehe platform. The research method is to use the completion data, combined with the sedimentary facies characteristics of the well area, using the completion logging data of the wells in different parts of the structure and the structural profile of adjacent wells to establish the north-southeast and west-trending formation correlation correlation profile. According to the rule of sedimentary rotation and the thickness of formation, the correlation of related strata is divided. On the basis of the conventional geological research method, we use drilling in combination with Landmark workstation interpretation system. Well logging, logging, oil testing and other completion data are difficult to solve, such as complex sedimentary development background, large depth drop, unclear understanding of structural characteristics and low accuracy of original seismic data. Based on the study of the distribution of residual oil in this area and the comprehensive geological research, the high-precision sedimentary structure secondary interpretation is carried out by using the multi-angle research method. The corresponding adjustment deployment and potential tapping scheme have been put forward, and good results have been obtained at present.
