| 摘 要： | 石龙场-柏垭油田位于四川盆地北部,是中国石化股份公司西南分公司最早投产的油气田.该油田地质条件复杂,勘探与开发风险大.截止目前,已完成钻井31口,共钻遇185个油气显示层.由于过去的油气层改造技术和设备都较现在的落后,一部分油气显示层没有获得很好的开发效果.基于上述问题,本文收集了有史以来钻遇的全部油气显示层的资料,并对其进行了综合性研究,建立了不同显示级别与油气层潜在产能的相关关系.提出了用以定量描述油气层开发潜力的"潜力指数".实例证明,本文提出的开发潜力评价方法能够反映评价油气层的开发潜力.SL11井大一段(下侏罗统自流井组大安寨段一段)是经过评价发现的最具潜力的油气层,其潜力指数为0.86.于1998年9月和2001年12月分别采取了两次不同的增产措施,均取得了显著的增产效果,取得了较好的经济效益.

| Abstract: | The Silongchang-Baiya oilfield,located in the northern Sichuan basin,is an oilfield that was put into production earliest by Southwest Subsidiary Company of SINOPEC.Geological conditions of the oilfield are so complicated that exploration and exploitation are very risky.Up to now,31 wells have been drilled and 185 zones with hydrocarbon shows have been recorded.However,the techniques and equipment for stimulating hydrocarbon zones were previously backward as compared with those nowadays;therefore some of the hydrocarbon show zones did not have good performances.On account of the above-mentioned problems,the authors have gathered almost all the data of the hydrocarbon show zones encountered by drill holes and conducted a comprehensive study to establish the correlation between different levels of shows and potential productive capacities of the reservoirs.The paper presents a new term,"potential factor"("PF" for short),to describe the production potential of reservoirs quantitatively.Case study shows that the method of evaluating the production potential presented by this paper can indicate the potential productive capacity of the evaluated reservoirs.The Dayi section in well SL11 is a hydrocarbon zone with the greatest potential in the field found by evaluation.Its potential factor is 0.86.Two different measures for stimulating its production were taken in September 1998 and December 2001 respectively.Both measures have successfully enhanced productivity remarkably and good benefits have been gained. |
