A new technique is developed to provide better identification of reservoir flow units constituting the producing formation. This technique is based upon considering fluid, rock, rock-fluid properties and flow mechanics of oil reservoirs. Actual reservoir data of porosity, permeability, oil/water relative permeability, air/brine capillary pressure are used to test the validity of this technique and also to compare obtained results with other techniques such as; permeability-porosity correlation, the J-function, and the Reservoir Quality Index (RQI) concepts.The results indicated that permeability-porosity correlation can not be developed for severe heterogeneous reservoirs. The results showed that the Reservoir Quality Index concept is capable of identifying the flow units while the J-function concept is quiet poor. Furthermore, a more refined and harmonic identification of flow units is obtained for all identified flow units by using the newly-developed technique. The new technique also is capable to provide information about the connectivity of different flow units through the inter-well regions.

我国多数低渗气藏存在不同程度的超低含水饱和度现象,在气藏开采过程中会造成水锁。针对平湖气田P11层气藏岩心进行了水锁实验。水锁实验结果表明,利用测井解释的原始含水饱和度进行水锁评价时,测井解释的原始含水饱和度高于岩心束缚水饱和度,说明PH5井P11层气藏不存在水锁伤害。但是现场实践表明,低渗气藏测井解释的原始含水饱和度偏高。估计平湖气田的原始含水饱和度在40-45%,利用估计的原始含水饱和度进行水
在高含硫气藏开发过程中,随着气体的产出,地层压力不断下降,存在于流体中的过饱和硫元素就会析出并可能沉积到岩石孔隙表面或喉道中,这种硫沉积现象会严重影响该类气藏的开发效果。通过元素硫沉积影响因素的分析和评价,运用人工神经网络理论建立高含硫气藏硫沉积神经网络预测模型。利用该模型预测高含硫气藏开采过程中,元素硫析出沉积特点和规律,分析不同产能下元素硫的沉积规律,在此基础上选择合理的开采速度,防止硫沉积对
流动单元的划分可以使油藏描述更精细,从而更准确地反映储层的非均质性,储层流动单元的研究对于油气田开发,特别是油田开发进入中高含水期,对二次采油和三次采油具有重大的现实意义。流动单元与剩余油分布存在着密切的关系,将流动单元研究和剩余油研究结合起来,可为改善油田开发效果,提高油气采收率提供可靠的地质依据。通过对某复杂断块油藏流动单元进行研究,从影响剩余油分布的静态参数(地质因素)出发,根据储层沉积相带

加强剩余油分布的研究对于老油田调整挖潜、提高采收率具有重要的意义,准确预测剩余油的分布要求在数据获取和剩余油饱和度计算的方法上有所突破,采用新的测量技术是关键所在。本文总结了剩余油测井定量分析(剩余油饱和度计算)发展过程中常规测井方法、CHFR测井方法、RMT与PND技术等单井测井方法,井间地震、VSP、四维地震、以及井地电位测量方法的剩余油空间分布预测技术。从实现机理、使用条件、适用性等方面进行
气井产能是气田开发方案设计、气井配产、地面建设以及开发方案调整的依据和基础,历来受到高度重视。对气井产能进行分析研究,可以准确预测气井的动态,并了解气层的特性,为合理、科学开发气田提供充分依据。川东北罗家寨、普光等高含硫气田由于单井产量高、部分井存在硫堵塞等现象,导致产能试井曲线异常,部分井资料出现负斜率现象。本文从渗流力学出发,分析了高含硫气藏存在的渗流模式,建立了附加表皮、复合渗流模型等产能试
