将广义Kопытов预测模型和乙型水驱曲线方法有机的结合起来,得到了油田开发中后期——递减时期的一种预测水驱开发油田的含水率、产油量、产水量及其相应的累积产量随开发时间变化的方法,此方法克服了在水驱油田预测开发指标中二者所存在的局限性。 相似文献

吉林油田同位素吸水剖面测井采用~(113)In同位素追踪技术,根据同位素追踪过程解释基本可以判断配水层段吸水情况。但是在注水井存在沾污、大孔道以及串槽等影响时,吸水面积确定比较困难。在同位素测井中增加井温、流量参数,通过多参数综合解释,不仅可以对沾污影响进行合理校正,确定准确的小层吸水量,而且能够正确判断各级封隔器、配水器的工作情况,在地层存在大孔道的情况下,确定地层的吸水面积。吸水剖面综合解释方法在吉林油田已普遍应用,见到明显的效果。 相似文献

Volcanic rocks of the late Mesozoic are very important reservoirs for the commercial natural gases including hydrocarbon, carbon dioxide and rare gases in the northern Songliao Basin. The reservoir volcanic rocks include rhyolite, andesite, trachyte, basalt and tuff. Facies of the volcanic rocks can be classified into 5 categories and 15 special types. Porosity and permeability of the volcanic reservoirs are facies-controlled. Commercial reservoirs were commonly found among the following volcanic subfacies: volcanic neck (I1) , underground-explosive breccia (I3), pyroclastic-bearing lava flow (II3), upper effusive (III3) and inner extrusive ones (IV1). The best volcanic reservoirs are generally evolved in the interbedded explosive and effusive volcanics. Rhyolites show in general better reservoir features than other types of rocks do. 相似文献

吉林油田乾146区块经多年开采,已经进入高含水、高采出阶段。通过储层流动单元研究,运用多参数模糊聚类方法将该区高台子油层由好至差划分为A、B、C、D、E 5类储层流动单元。查明了区内主要目的层系各含油小层的储层流动单元发育特征:40、39小层主要发育A、B类优质储层流动单元,42、41、38小层则以C、D、E类储层流动单元为主,各小层储层流动单元类型及展布与初始产能吻合度较高,表明储层流动单元类型的差异是控制本区油气分布的重要因素之一。综合油藏地质特征及油田开发动态数据,对各储层流动单元的注采渗流体系进行了深入剖析,归纳总结出乾146区块高台子油层XII砂组中剩余油分布的5条规律,据此在剩余油分布预测区部署了1口扩边井和2口老区加密井,投产后分别获得了11.2t/d、5.5t/d和8.6t/d的初始产能。 相似文献

深层地震勘探野外资料采集的关键是在保证原始资料一定信噪比的基础上,同时兼顾分辨率,激发井深是决定资料品质的重要因素之一。通过对虚反射滤波作用分析,提出了充分利用虚反射能量设计最佳激发井深,增强下传地震波能量的采集方法。理论分析和试验资料表明,在高速层下4~7m的最佳激发岩性深度是深层勘探的理想井深。 相似文献

Discovery and Significance of High CH4 Primary Fluid Inclusions in Reservoir Volcanic Rocks of the Songliao Basin, NE China 总被引:2,自引:0,他引:2

Comparing compositions of the fluid inclusions in volcanic rocks to the contents and isotopes of the gases in corresponding volcanic reservoirs using microthermometry, Raman microspectroscopy and mass spectrum analysis, we found that: (1) up to 82 mole% methane exists in the primary inclusions hosted in the reservoir volcanic rocks; (2) high CH4 inclusions recognized in the volcanic rocks correspond to CH4-bcaring CO2 reservoirs that are rich in helium and with a high ^3He/^4He ratio and which show reversed order of 813C in alkane; (3) in gas reservoirs of such abiotic methane (〉80%) and a mix of CH4 and CO2, the enclosed content of CH4 in the volcanic inclusions is usually below 42 mole%, and the reversed order of δ^13C in alkane is sometimes irregular in the corresponding gas pools; (4) a glassy inclusion with a homogeneous temperature over 900℃ also contains a small portion of CH4 although predominantly CO2. This affinity between gas pool and content of inclusion in the same volcanic reservoirs demonstrates that magma-originated gases, both CH4 and CO2, have contributed significantly to the corresponding gas pools and that the assumed hydrocarbon budget of the bulk earth might be much larger than conventionally supposed. 相似文献
