【摘要】：馬廠北部復(fù)雜帶油氣儲量豐富,但由于構(gòu)造極復(fù)雜,認識難度大,地層對比相當困難,導(dǎo)致開發(fā)效果很差。要達到提高動用地質(zhì)儲量,增加產(chǎn)能,提高采收率的目的,就必須重新進行落實構(gòu)造等基礎(chǔ)研究。由于該區(qū)斷層控制程度低,構(gòu)造不清,一直未進行系統(tǒng)的地質(zhì)研究。構(gòu)造體系及儲集層分布規(guī)律研究不夠,特別是油藏描述精度不夠制約了該地區(qū)的油藏評價及新區(qū)產(chǎn)能建設(shè)。本次處理解釋就是通過開發(fā)出的多尺度分析地震資料處理軟件處理其地震資料并對馬廠北部復(fù)雜帶地震資料進行精細構(gòu)造解釋,加強該區(qū)油藏的整體解剖與評價,為該油藏的滾動開發(fā)提供科學(xué)的依據(jù),并在此基礎(chǔ)上結(jié)合該區(qū)下一步滾動關(guān)鍵井的鉆探與評價,形成新區(qū)產(chǎn)能建設(shè)陣地,提高該區(qū)的整體開發(fā)水平。在多尺度分析地震資料處理軟件開發(fā)方面,通過對小波變換及多尺度分析方法原理的研究,經(jīng)過試驗研究選取合適的基小波和分解層數(shù),基于matlab平臺并利用小波變換工具箱開發(fā)出多尺度分析地震資料處理軟件。在此基礎(chǔ)上,小尺度下的分解結(jié)果用于分析地質(zhì)體的細小結(jié)構(gòu),大尺度下的分解結(jié)果用于分析地質(zhì)體的整體結(jié)構(gòu)。在三維地震資料精細解釋方面,三維地震資料包含了地層、構(gòu)造和斷裂等諸多信息,是油氣勘探和開發(fā)中的一種重要基礎(chǔ)數(shù)據(jù)。三維地震解釋是一項非常復(fù)雜、工作量巨大且具有不確定性的任務(wù)。在這次研究中,我們建立地震解釋數(shù)據(jù)庫,通過VSP速度資料、時深數(shù)據(jù)或合成記錄建立地震反射同相軸與地質(zhì)層位之間的對應(yīng)關(guān)系進行層位精細標定。利用三維可視化技術(shù)、選取地震解釋標志反射層、多種子點層面立體追蹤技術(shù)、螞蟻追蹤斷層技術(shù)、相干體檢測技術(shù)、井震結(jié)合評價技術(shù)等手段,遵循一定的解釋思路,對層面和斷層進行解釋。在完成層位解釋和斷層解釋工作后,再進行構(gòu)造成圖,獲得需要的各種圖件。根據(jù)本項目的研究目標,進行綜合地質(zhì)分析。從地震地質(zhì)層位的精細標定、精細構(gòu)造解釋等幾個方面進行大量研究工作,利用多源信息優(yōu)選出有利目標,從而為油田的擴邊挖潛提供地震地質(zhì)依據(jù)。本論文通過以上對馬廠北部復(fù)雜帶地震資料的處理解釋,得到了大量準確可靠的成果圖件,并開發(fā)出了新的地震資料處理軟件以提高該區(qū)地震資料品質(zhì),加強了復(fù)雜斷塊群地震資料處理技術(shù)實力,為進一步挖掘復(fù)雜斷塊區(qū)含油斷塊的潛力,實現(xiàn)油田的增儲穩(wěn)產(chǎn),促進油田發(fā)展都具有重大意義。
[Abstract]:The complex zone in northern Machang is rich in oil and gas reserves, but the development effect is very poor due to the complexity of structure, the difficulty of understanding and the difficulty of stratigraphic correlation. In order to increase the production reserves, productivity and oil recovery, it is necessary to carry out structural research again. Because of the low degree of fault control and unclear structure, no systematic geological research has been carried out in this area. The study of structural system and reservoir distribution law is not enough, especially the insufficient precision of reservoir description restricts the reservoir evaluation and productivity construction in the new area. This processing interpretation is to strengthen the overall anatomy and evaluation of the reservoir in this area by processing the seismic data and fine structural interpretation of the seismic data of the complex zone in the northern part of Machang through the development of a multi-scale seismic data processing software. It provides a scientific basis for the rolling development of the reservoir, and on the basis of this basis, combining with the drilling and evaluation of the next key rolling wells in this area, the production capacity construction position of the new area is formed, and the overall development level of the area is improved. In the development of multi-scale analysis seismic data processing software, through the research of wavelet transform and the principle of multi-scale analysis method, the appropriate basic wavelet and decomposition layer number are selected through experimental research. Based on matlab platform and wavelet transform toolbox, a multi-scale seismic data processing software is developed. On this basis, the results of decomposition at small scale are used to analyze the fine structure of geological bodies, and the results of decomposition on large scales are used to analyze the whole structure of geological bodies. In the fine interpretation of 3D seismic data, 3D seismic data contain a lot of information, such as strata, structures and faults, which is an important basic data in oil and gas exploration and development. 3D seismic interpretation is a very complex, heavy and uncertain task. In this study, we set up the seismic interpretation database, establish the correspondence relationship between seismic reflection phase axis and geological horizon by VSP velocity data, time-depth data or synthetic record to calibrate the horizon fine. By using 3D visualization technology, we select seismic interpretation mark reflection layer, multi-seed point level stereoscopic tracing technology, ant tracing fault technology, coherent volume detection technology, well shock combined evaluation technology and so on, and follow certain interpretation ideas. Explain the layers and faults. After the layer interpretation and fault interpretation are completed, the necessary maps are obtained. According to the research goal of this project, comprehensive geological analysis is carried out. A great deal of research work has been done from several aspects such as fine calibration of seismic geological horizon fine structural interpretation and so on. The favorable targets are selected by using multi-source information so as to provide the seismic geological basis for exploiting the expanding edge of oil fields. Through the above interpretation of the seismic data of the complex belt in the northern part of Machang, a large number of accurate and reliable maps have been obtained, and a new software for seismic data processing has been developed to improve the quality of seismic data in this area. The technical strength of seismic data processing in complex fault block group is strengthened. It is of great significance to further excavate the potential of oil-bearing fault block in complex fault block area, to realize the increase of reservoir and stable production of oil field and to promote the development of oil field.
