【摘要】：大慶杏樹崗油田杏六區(qū)開發(fā)已經(jīng)進(jìn)入了特高含水期,目前油田面臨剩余可采儲量有限、剩余油分布高度分散、地質(zhì)情況復(fù)雜、開發(fā)難度加大、產(chǎn)量遞減迅速等世界級開發(fā)難題,歷經(jīng)數(shù)年的水驅(qū)后,油田層系間三大矛盾凸顯、注采關(guān)系復(fù)雜、挖潛效果很差,因此,如何有效的平衡上述矛盾,解決上述問題,為油田持續(xù)增產(chǎn)穩(wěn)產(chǎn)、制定科學(xué)合理可持續(xù)的發(fā)展策略,已經(jīng)成為現(xiàn)在高含水后期油田面臨的普遍問題。本文以大慶杏樹崗油田杏六區(qū)為研究對象,對該區(qū)塊的地質(zhì)特征,儲層特征,開發(fā)現(xiàn)狀,剩余油潛力,區(qū)塊存在的主要問題及矛盾進(jìn)行了分析評價。首先整理分析了杏六區(qū)不同增產(chǎn)措施后的油水井?dāng)?shù)據(jù),從油水井壓裂、油井補(bǔ)孔、油井堵水、水井酸化等方面進(jìn)行具體的增產(chǎn)措施效果分析評價,為了知道增產(chǎn)各影響因素與日增油量之間的關(guān)聯(lián)程度,本論文采用單因素分析法、灰色關(guān)聯(lián)法以及人工神經(jīng)網(wǎng)絡(luò)法以壓裂井例,對各因素進(jìn)行了關(guān)聯(lián)性評價。對杏六區(qū)油田開發(fā)評價具有一定指導(dǎo)意義。
[Abstract]:The development of Xingshugang Oilfield in Daqing Xingshugang Oilfield has entered an extremely high water-cut period. At present, the oilfield is faced with world-class development problems such as limited remaining recoverable reserves, highly dispersed remaining oil distribution, complex geological conditions, increased difficulty in development and rapid decline in production. After several years of water flooding, the three major contradictions between layers in oil fields are prominent, the relationship between injection and production is complex, and the effect of tapping potential is very poor. Therefore, how to effectively balance the above contradictions and solve the above problems in order to increase production and stabilize production continuously, Making scientific, reasonable and sustainable development strategy has become a common problem in the later stage of high water cut oilfield. This paper takes Xingshugang oilfield as the research object, and gives the geological characteristics, reservoir characteristics and development status of the block. The remaining oil potential, the main problems and contradictions existing in the block are analyzed and evaluated. Firstly, the data of oil and water wells after different measures of increasing production are analyzed and analyzed, including fracturing of oil and water wells, filling holes in oil wells, water shutoff in wells, etc. In order to know the correlation between the influence factors of increasing production and daily oil production, the single factor analysis method is used in this paper. The grey correlation method and artificial neural network method are used to evaluate the correlation of various factors with the example of fracturing wells, which has a certain guiding significance for the development evaluation of Xingliu Oilfield.
