基于多矿物模型分析的最优化测井解释在X油田中的应用研究

APPLICATION OF THE OPTIMIZED WELL LOGGING INTERPRETATION IN X OILFIELD BASED ON MULTIMINERAL MODEL ANALYSIS

迄今为止，传统的POR、SAND和CRA等测井分析方法与程序基本上是按照固定的解释模型，采用有限的几种测井资料分别计算储层参数来进行地层评价及油气分析。实质上，它们基本上都是用计算机来模拟人工解释过程。虽然这些测井分析方法与程序在过去和现在均起着重要作用，但它们都存在某些重要的缺陷。例如，在计算过程中未能充分利用现有的所有测井资料；不能灵活地采用不同的解释模型和解释方法；难以有效地评价含两种以上矿物的复杂岩性地层；对计算结果又缺乏自我质量检验手段等等。基于多矿物模型分析的最优化测井解释技术采用新的理论模型，先进的数学计算方法和灵活的程序设计，建立测井曲线L、地层矿物含量V、测井矿物响应参数P和测井相F之间的关系，可高质量快速处理测井资料，得到连续的地层矿物含量剖面、岩性剖面和各种储层特性参数。利用多矿物模型分析的最优化测井解释方法处理X油田的数十口并资料，效果良好，与录井资料较为一致。

So far,conventional POR,SAND and CRA well logging analytical methods and procedures are basically to calculate reservoir parameters with some limited logging data according to a certain interpretation model to make formation evaluation and oil or gas analysis.Actually they are all manual interpretation simulation with computers.Although these methods and procedures play an important role in the past and at present,they have some serious shortcomings.The optimized logging interpretation technology based on a multimineral model uses a new theoretical model,advanced mathematical computation method and flexible programming to establish a relationship among L logging curve, formation mineral content V,logging mineral response parameter P and logging faces.It can process logging data fast with high quality to obtain a sequential formation mineral content prof'de, lithological profile and all kinds of reservoir characteristic parameters.It has been used in processing the data of 10 wells in X oitfield and achieved good result in accordance with mud logging data.
