主要测井曲线及其含义

类型原理及特点应用范围使用条件特征曲线自然伽马一、原理：自然伽玛测井是探测天然放射性的一种测井方法。

地层中的主要发射性元素为铀系、钍系和钾40系，这三种元素发出的伽玛射线是一种类似于光的高频电磁波，当伽玛射线被探头接收时，便损失了大部分能量并转换为可见光，然后由光电倍增管转换为电脉冲，其数量就反映了伽玛射线的强度。

二、特点：a、对于放射性物质含量均匀各向同性的岩层，当上、下围岩的放射强度相等时，曲线对称于地层中点；b、对着地层中点，曲线呈极大值，并且随着岩层厚度增加而增大，当厚度是井径3倍时，极大值为常数，曲线的极大值与地层放射性强度成正比。

c、当地层厚度是井径3倍时，由曲线的半幅点确定的岩层厚度为真厚度。

一、应用范围：a. 划分岩性及进行地层对比泥岩和页岩显示明显的高放射性。

在泥岩剖面上，纯砂岩显示最低值，泥岩显示最高值，泥质砂岩界于中间，并且随着泥质含量增高，自然伽玛数值也增高。

岩浆岩、富含放射性矿物的砂岩或石灰岩等比较咼。

一般情况下，石膏、硬石膏、岩盐和纯的石灰岩、白云岩的放射性很低。

白云岩往往比石灰岩具有较咼的放射性。

图为自然伽马在各种岩性的变化的相对幅度。

b. 计算泥质含量，是普遍的应用方法，是各种程序计算泥质含量的手选曲线。

但由于，有时砂岩地层有钾长石发育，使自然伽马在砂岩地层数值也不降低。

辽河油田西部凹陷多数由于钾长石发育，使自然伽马分层能力不好，不能用来计算泥质含量。

用自然伽玛测井曲线可以划分砂泥岩、计算泥质含量、识别特殊岩性、进行地层对比、评价生储盖的条件等。

广泛应用二、影响因素：a、地层的厚度；b、测井速度和仪器时间常数；c、仪器标准化的影响；d、井参数的影响；e、放射性测井曲线统计起伏误差的影响f、井参数的影响1）、泥浆如果井内没有泥浆，则井对伽玛射线吸收弱；而当有泥浆时，井内介质对伽玛射线的吸收较强。

可是由于泥浆中含有粘土，具有一定的放射性，这就抵消了伽玛射线强度的减弱，因此，井筒内泥浆一般对自然伽玛射线影响不大。

四、岩石组合及层序的测井解释模型不同沉积环境下形成的地层，在纵向上有不同的岩相组合，在横向上有不同的分布范围及沉积体的几何形态，砂体的内部具有不同的粒度，分选性，泥质含量。

（一）、测井曲线要素及其常规组合测井曲线地质意义1．幅度：分为低幅、中幅、高幅三个等级2．形态①钟形：反映水流能量向上减弱它代表河道的侧向迁移或逐渐废弃。

②漏斗：反映砂体向上部建造时水流能量加强，颗粒变粗分选加好，代表砂体上部受波浪收造影响，此外也代表砂体前积的结果。

③箱形：反映沉积过程中能量一致，物源充足的供应条件，是河道沙坝的曲线特征④对称齿形：常见的一种曲线形态，它多以充刷、充填作用为主，具有正粒序。

⑤反向齿形：常见的一种曲线形态，河水道末稍前积式充填为主具有反粒序。

⑥正向齿形：为充填堆积特征，常代表洪水作用下的堆积具有对称粒序。

⑦指形：代表强能量下的中层粗粒堆积，如海滩、湖滩⑧漏斗-箱形：代表丰富物源供应下的水下沙体堆积，为河口堆积的典型特征。

⑨箱形-钟形：环境为有丰富的物源，但后期由于河道迁移或废弃导致能量衰减，具有河道的均质沉积，到后期正向粒度的沉积。

⑩上为漏斗-箱形，下为漏斗-钟形：代表河道在迁移摆动条件下，有丰富物源供应的水道充填式堆积。

⑧、⑨、⑩统称为复合形，表示由两种或两种以上曲线形态组合，表示一种水动力环境向另一种环境的变化。

各类形态又可进一步细分为光滑形和锯齿形。

3.接触关系顶底接触关系反映砂体沉积初期、末期水动力能量及物源供应的变化速度，有渐变和突变两种，渐变又分为加速、线性和减速三种，反映曲线形态上的凸型、直线和凹型。

突变往往表示冲刷(底部突变)或物源的中断(顶部突变)。

单砂层顶部突变，反映了砂体沉积末期水动力、物源供应条件。

顶部突变代表物源供应的突然中断，顶部加速渐变代表水流能量在后期急刷减退或物源供应减少，多与河道末期沉积有关，顶部匀均渐变呈斜线形代表均匀的能量减退的过程。

为河道侧向迁移的典型特征，顶部减速渐变代表能量或物质供应在后期缓速消退，水下河道常具有这种特点，代表后续水流滞后沉积。

1.声波时差曲线：在泥砂岩剖面上，砂岩显示低时差，其数值随孔隙度的不同而不同；泥岩一般为高时差，其数值随压实程度的不同而变化；页岩的时差介于泥岩和砂岩之间；砾岩的时差一般都较低，并且越致密声波时差值越低．在碳酸盐剖面上，致密石灰岩和白云岩声波时差最低，如含有泥质时，声波时差增高，若有孔隙和裂缝，声波时差明显增大，甚至出现周波跳跃．石膏岩盐剖面，渗透性砂岩最高？，泥岩（含钙质、石膏多）与致密砂岩相近，泥质含量高时增大，岩盐扩径（井直径）严重，周波跳跃？气体比油水的时差要大的多，岩性一定时候，含气层段出现周波跳跃。

2.自然Gamma曲线：在泥砂岩剖面上，纯砂岩在自然Gamma曲线上显最底值，泥岩显最高值，粉砂岩和泥质砂岩介于二者之间，并随着岩层中泥质含量增加曲线幅度增加；在碳酸盐剖面上，泥岩和页岩显最高值，纯的石灰岩、白云岩有最低值，而泥灰岩、泥质石灰岩、泥质白云岩自然Gamma测井曲线值介于二者之间，并随泥质含量增加幅值增大．3.微电极测井曲线中砂岩异常幅度差大于粉沙岩异常幅度差．4.泥岩在密度测井曲线上值较高而煤层密度测井值在剖面上看很低5.在淡水泥浆的沙泥岩剖面井中，自然电位测井曲线以大断泥岩层部分的自然电位曲线为基线，此时出现负异常的井段都可认为是渗透性岩层。

在含有泥质的砂岩中由于泥质对溶液产生吸附电动势使总电动势降低。

所以纯砂岩的自然电位异常幅度要比泥质岩石的异常幅度大，而且随着砂岩中泥质含量的增加，自然电位异常幅度会随之减小自然电位与自然伽马对砂岩泥岩都很敏感，但是自然电位容易受到流体性质、岩层厚度的影响，含油气或者薄层时，幅度很低。

粉砂和泥的比值大于1:2,幅度趋于0.自然伽马虽然也受到层厚影响，层厚小于0.8米时才开始显现影响。

以上为一般情况（正常压实），如果欠压实，情况相反，砂岩出现高时差，如渤海湾明化镇组所以具体地区具体问题具体分析（要根据岩心资料建立具体解释模型）6.感应测井为了获取井下地层的原始含油饱和度资料，用油基钻井液钻井;为了不破坏井下地层的渗透率，有时采用空气钻井；这时井中没有导电介质，不能传导电流，为了解决这个问题，发明了感应测井。
