【摘要】 龙虎泡油田是大庆长垣外围西部开发较早的主力油田,目前已进入高含水期,萨葡油层水淹程度较高,有必要加大注采系统调整力度。由于现井网油层动用状况差异较大,存在大量剩余油,而且地下油水分布条件复杂多变,对油藏水淹特征认识程度也不够深入。针对大庆长垣外围西部萨葡油层重点区块开展水淹层测井解释技术研究。建立较完善的水淹层测井解释标准。本文在对研究区储层特征综合分析的基础上,应用概率图法将研究区储层划分为三类,通过开展油藏条件下导电机理实验,搞清不同岩石物理相储层水淹过程中电性响应变化规律；在水淹层定性识别方法研究中,通过引入曲线相对重心、椭圆度、饱满系数等参数,应用孔隙度和电阻率测井曲线重叠法,建立了四种不同韵律油层的水淹模型,从而实现对储集层含油气性或含水性信息的定性判断；在水淹层测井定量评价中,在混合泥质含钙砂岩有效介质通用电阻率模型基础上针对储层高泥含钙的特点,针对储层高泥含钙的特点重点开展了饱和度定量评价技术研究,分析了中低渗透油田储层的水淹规律,建立了水淹层识别方法和标准。更多还原

【Abstract】 Longhupao oil field is the early exploration important block by Daqing placanticline outskirts west, and entering high water cut stage, Sapu petroleum reservoir water flooding degree is high, must increase water flooding regime dynamics regulation. Because present well network oil layer use condition divergence larger, existence a great quantity of oil remaining, moreover subsurface profit distribute complex changeable, insufficiently is not deep enough also thorough to the reservoir flooding characteristic. in view of Daqing placanticline outer-ring west Sapu oil layer key sub-area development flooding level well logging interpretation engineering research.This paper in to studies the area reservoir characteristic multidisciplinary analysis in the foundation, will discuss using the graph theory clustering procedure to study the area reservoir division will be three kinds, through the development hydrocarbon reservoir condition under electric conduction mechanism experiment, will clarify in the different rock physics facies reservoir flooding process the electrical property answer change regular pattern. In the water flooded layer determine the nature recognition method research, through the introduction curve relative core, ellipticity, parameter and so on plump factor, the application porosity and resistivity logging curve deconvolution, has established four type of different rhythm oil layers waterflooding model, thus realizes to the reservoir contains oil/gas the disposition or contains water the natural information determine the nature judgement; In the flooding level oil well logging quantitative evaluation, take the degree of saturation appraisal as the core, the innovation mud character develops the blend to contain the calcium sandstone effective medium current specitic resistance model. This article through to the Daqing placanticline outer-ring west the Sapu oil layer development swept layer well logging interpretation technical research, has analyzed middle/low penetration oil field reservoir flooding rule, has established the flooding level recognition method and the standard. In view of reservoir the building store height mud to contain the calcium the characteristic to carry out the degree of saturation quantitative evaluation engineering research with emphasis.更多还原
