【摘要】：隨著油田開發(fā)的不斷深入,薩南開發(fā)區(qū)開發(fā)進入中后期,含水率上升越來越快,產(chǎn)量加速減少,經(jīng)過長時間的開發(fā)后,儲層中剩余的可采儲量也越來越少,地質(zhì)儲量和可采儲量逐漸失去平衡,這種矛盾日益明顯,因此,為了解決這些問題,為了保證油田產(chǎn)量的穩(wěn)定,尋找新的儲量資源,對于還沒有開發(fā)的儲量,要最大限度的將其開采出來是唯一的方法。油水同層段儲層的儲量已經(jīng)占了有日常儲量的很重要的一個部分,尤其是油水同層段儲層中的偏油層,又有一定的挖掘潛力,因此為了解決儲采比問題,落實穩(wěn)產(chǎn)目標,使油田的儲量不損失,以薩南開發(fā)區(qū)為典型區(qū)塊開展了油水同層段偏油層識別方法研究。首先,對取心井巖心利用巖石熱解技術(shù)、熱解蒸發(fā)烴氣相色譜技術(shù)、熒光顯微圖像技術(shù)等進行實驗,并將其與錄井資料結(jié)合起來,分析油水層的響應(yīng)特征,重新綜合判定了整個薩南油田薩東油水過渡帶、薩西油水過渡帶、南一區(qū)到南三區(qū)、南四區(qū)到南八區(qū)四個區(qū)塊的油水同層段深度。然后通過取心井的巖心分析資料,試油資料和測井資料統(tǒng)計和分析,再一次確定了薩南開發(fā)區(qū)儲層的油水同層以及其相應(yīng)的四性關(guān)系;再利用相滲曲線法,經(jīng)濟極限法,壓汞法和經(jīng)驗統(tǒng)計法來確定研究區(qū)油水同層段偏油層的物性下限;進而根據(jù)物性標準和測井數(shù)據(jù)建立電性與物性交會圖版,確定出薩南開發(fā)區(qū)儲層油水同層段偏油層電性下限,準確識別出油水同層段偏油層段,為油田后期動態(tài)開發(fā)調(diào)整方案的制定提供更可靠的依據(jù)。
[Abstract]:With the deepening of oilfield development, the development of Sanan Development Zone enters the middle and late stage, the water cut rises more and more quickly, the output decreases rapidly, and after a long period of development, the remaining recoverable reserves in the reservoir become less and less. The contradiction between geological reserves and recoverable reserves is becoming increasingly out of balance. Therefore, in order to solve these problems, to ensure the stability of oilfield production and to find new reserves, for reserves that have not yet been developed, It is the only way to extract it to the maximum extent possible. The reserves of reservoirs in the same formation of oil and water have already taken up a very important part of the daily reserves, especially in the reservoirs of the same formation of oil and water, which has a certain potential to excavate. Therefore, in order to solve the problem of the ratio of reservoir to production, and to implement the goal of stable production, In order to avoid the loss of oil reserves, the identification method of oil-water reservoir in the same zone is studied in this paper, taking Sanan Development Zone as a typical block. Firstly, the core of coring well is tested by using rock pyrolysis technology, pyrolytic vaporization hydrocarbon gas chromatography technology, fluorescence microscopic image technology and so on, and the response characteristics of oil-water layer are analyzed by combining it with logging data. The depth of the same zone of oil and water in the four blocks from South one to South three and from South four to South eight has been determined by re-synthesizing the oil and water transition zone of the whole Sanan oilfield, the oil and water transition zone of Saxi oil and water. Then through the core analysis data of coring well, oil test data and logging data statistics and analysis, once again determine the reservoir in Sanan development zone and the corresponding four properties; The lower limit of physical properties of the oil-water layer in the same zone is determined by using the phase permeability curve method, the economic limit method, the mercury injection method and the empirical statistics method. Furthermore, according to the physical property standard and logging data, the electric and physical intercourse meeting chart is established, and the lower limit of electric property of the oil / water partial oil layer in the same section of the reservoir in Sanan Development Zone is determined, and the partial oil layer section of the same oil and water zone is accurately identified. It provides a more reliable basis for the formulation of the adjustment scheme of oilfield later dynamic development.
