【摘要】：進入特高含水期以來,喇嘛甸油田水驅各套層系井網間開發(fā)狀況存在差異,各項開發(fā)指標出現(xiàn)新的變化特點,水驅開發(fā)面臨儲量轉移、剩余油零散、層內動用差異大、儲采比低等諸多矛盾,開發(fā)調整難度越來越大。如何保證水驅在無新增可采儲量的狀況下可持續(xù)開發(fā),是急需研究的課題。為此,本文從喇嘛甸油田地質沉積特點入手,通過水驅各層系可采儲量評價方法、各層系各項指標變化規(guī)律研究方法和未來合理產量規(guī)模預測方法,對水驅各項開發(fā)指標變化影響因素和進入特高含水期后開發(fā)指標的變化規(guī)律進行了系統(tǒng)分析,并得出了特高含水期水驅合理開發(fā)指標,明確水驅今后調整方向,提高預測的科學性和準確率,為指導水驅特高含水期年度規(guī)劃提供有力依據(jù)。本文研究形成的開發(fā)特點認識、潛力研究以及規(guī)律認識對指導油田開發(fā)調整,提高油田開發(fā)效益具有非常重要的意義。在指導水驅規(guī)劃過程中,確定各項合理指標,減少無效循環(huán)產量,規(guī)避低效無效開發(fā),提高油田開發(fā)效益。
[Abstract]:Since entering the ultra-high water cut stage, there are differences in the development status among the well patterns of each set of water drive strata in Lamadian Oilfield, and new changes have appeared in each development index. The water drive development is faced with reserve transfer, the remaining oil is scattered, and the intra-layer production is very different. Many contradictions, such as low storage-production ratio, make it more and more difficult to develop and adjust. How to ensure the sustainable development of water drive without new recoverable reserves is an urgent research topic. Therefore, this paper starts with the geological and sedimentary characteristics of Lamadian Oilfield, through the evaluation method of recoverable reserves of each layer system of water drive, the research method of the variation law of various indexes of each layer system and the prediction method of reasonable production scale in the future. The influencing factors of water drive development index and the change law of development index after entering ultra high water cut stage are systematically analyzed, and the reasonable development index of water drive in ultra high water cut stage is obtained, and the adjustment direction of water drive in the future is clarified. To improve the scientific nature and accuracy of prediction, and to provide a powerful basis for guiding the annual planning of ultra-high water cut stage of water drive. The understanding of development characteristics, potential and law formed in this paper is of great significance to guide the adjustment of oil field development and improve the efficiency of oil field development. In the process of guiding water drive planning, the reasonable indexes are determined, the invalid cycle production is reduced, the inefficient and invalid development is avoided, and the oil field development benefit is improved.
