龙虎泡油田高含水期开发潜力研究
|
摘要
松辽盆地北部的大庆长垣西部地区,地质条件复杂,油藏类型多为“低产、低渗、低丰度”的构造、断层、岩性复合油藏。龙虎泡油田为典型的三低油田,构造位置位于松辽盆地中央坳陷区齐家-古龙凹陷西侧,是龙虎泡-红岗阶地北端一个轴向近于南北的短轴三级背斜构造。开采层位主要是萨尔图油层、葡萄花油层和高台子油层,以开采萨尔图油层为主,动用含油面积27.5km~2,地质储量1316×10~4t。龙虎泡油田萨葡油层主要受北部物源影响,为浅湖-三角洲前缘相沉积。
龙虎泡油田在先后经历了天然能量开采、笼统注水、分层注水、加密调整等开发阶段后,目前油田已进入高含水期开发,尽管通过加大注水调整和调剖力度,但自然递减依然较快,为了改善龙虎泡油田高含水期开发效果,对该油田进行了系统研究,以搞清开发潜力。
开展了精细油藏描述研究,在划分流动单元的基础上,根据注入产出监测资料,动静态结合判断水井的水驱方向、油井的见水层位和方向,搞清剩余油分布状况和规律;通过建立产量递减模型,联立产量衰减方程和水驱特征曲线方程,研究油田开发指标变化规律及预测。
在剩余油分布规律研究基础上,通过数值模拟等综合技术,研究加密调整可行性,同时,通过岩电分析,研究水淹层解释标准;动静结合,落实构造油藏的油水边界,油水分布规律及储层水淹情况和边部井的含水情况等;考虑萨尔图、葡萄花、高台子储层的空间分布情况,结合实钻井落实的断层情况,预测布井区的储层发育情况,确定合理的井距,采用灵活的方式布井。
The west region in Daqing of north of the Song Liao basin, the geology condition is complicated and the reservoir is the structure of low porosity, low permeability, low salinity, its type majority constructs oil to hide, the rock oil hide, compound of the oil hide. The Longhupao oil-field is typical of three low oil-fields, construct position is to be located on the Song Liao basin concavity area Qijia-ancient dragon hollow west side, is Longhupao-HongGang rank ground north carry a stalk to near south north of the minor axis be the third grade to carry on the anticline structure. Layer of mine is mainly SaErTu oil layer, the blossom of grape oil layer and GaoTaiZi oil layer and take mining the SaErTu oil layer as lord. Use to contain the oil area 27.5km~2,the geology keeps to measure 1316×10~4t.The Sa and Pu oil layer of the Longhupao oil-field are mainly subjected to a northern thing source influence and Be the deposition in the Delta Front Reservoir.
The Longhupao oil-field previously experienced natural energy to mine, general note water, layering to note water and encrypt adjustment etc. development stage after, the oil-field has already got into High Water-content a period a development currently, though note water adjustment and Profile Control strength through an enlargement, nature gradually decrease still quicker, for the sake of improvement the Longhupao oil-field High Water-content period develop effect, carried on system a research to that oil-field and make pure development potential. Open the exhibition fine reservoir description research, produce monitor data according to the infusion in dividing the line foundation of flow the unit, water which moves a static state to combine to judge water well gets rid of water layer and direction of the see of direction, oil well, make pure surplus oil to distribute condition and regulation and open an exhibition to lift a liquid experiment, raise to keep quantity to use degree; Pass to build up yield to gradually decrease model, unite to sign yield to reduce square distance and water to get rid of the characteristic curve square distance, study an oil-field development index sign variety regulation and estimate, Distribute a regulation research foundation in the surplus oil up, pass number emulation's etc. to synthesize a technique, the research encrypts an adjustment possibility,pass rock electricity analysis, carry out the illegitimate profit boundary that the structure oil hide and the illegitimate profit distributes regulation and keeps layer water to flood the contain of circumstance and side department well water circumstance etc. The space which considers that the SaErTu, the blossom of grape, GaoTaZi oil layer distributes a circumstance and combine solid artesian well to carry out of break layer circumstance, predict the layer growth circumstance of the cloth well keep of area, make sure the reasonable well be apart from and adopt vivid way cloth well.
