Description

基于凝胶的电测井探测器实体物理模拟装置及其形成方法 Detector physical entities based on the electrical logging simulation apparatus and method of forming a gel

技术领域 FIELD

[0001] 本发明属于石油电法测井装备研发领域,具体涉及一种能够对全尺寸电测井探测器进行复杂地层测井响应测试的、基于凝胶的实体物理模拟装置及其形成方法,用于验证电测井探测器的理论推导和数值模拟计算结果。 [0001] The present invention belongs to the field of well logging equipment research oil electrical method, particularly it relates to a complex formation logging log the whole size of the electrical response to the test probe, based on the physical entity simulation apparatus and method of forming a gel, theoretical analysis and numerical simulation and logging the electrical detector for calculating results.

背景技术 Background technique

[0002] 探测器物理模拟装置作为专用装备,用于对1:1全尺寸探测器进行测井响应特性(纵向、径向探测特性,测量精度,纵向分辨率等)的物理模拟,是对探测器设计中的数值模拟算法以及探测器制作方法和工艺的关键性验证环节,并为探测器优化设计提供可靠的依据。 [0002] The detector apparatus as a dedicated physical simulation equipment, for 1: 1 full size detectors log response characteristics (longitudinal, radial detection characteristics, measurement accuracy, vertical resolution, etc.) of the physical simulation is the detection the design algorithm and numerical simulation of the detector and the manufacturing method of the key validation process part, and the probe is designed to provide a reliable basis for the optimization. 物理模拟过程(也称为测井方法实验)是电测井探测器尤其是高端成像电测井探测器研发中不可或缺的重要环节。 Physical simulation (also referred to as a logging method experiment) electrically logging probe is especially high-end imaging electrically logging probe indispensable part in development.

[0003]目前对电测井探测器研究和生产中进行物理模拟和实验的主要方法如下。 [0003] The main method for physical simulation and experimental research and production to electrical detector logging follows.

[0004] I、导电橡胶法 [0004] I, the conductive rubber method

[0005] 用导电橡胶构建电测井探测器实体物理模拟装置是一种传统的方法,这种方法的弊端是由于橡胶的非亲水性导致导电介质往往采用金属或非金属颗粒,导致在导电机理上与石油储层的离子导电相异,不同电性模块间的耦合困难,大体积的硫化成型非常困难、均匀性差、造价较高且容易老化等;因此没有得到普遍应用,尤其是没有在近年来高端成像电测井仪器(如阵列感应、三分量感应和阵列侧向等)的物理模拟中得到应用。 [0005] Construction of electrically logging probe entity conductive rubber physical simulation device is a traditional method, the drawbacks of this approach is that the rubber of the non-conductive medium tends to result in a hydrophilic metal or non-metallic particles, conductive leads the mechanism and different ionic conductivity petroleum reservoir, difficult between different modules are electrically coupled to a large volume of vulcanization molding is very difficult, poor uniformity, higher cost and easy to aging; therefore not been widely used, especially not in the in recent years, high-end imaging applications to obtain an electrical logging tool (sensor array, and an array of three-component sensing lateral, etc.) physical simulation.

[0006] 2、大体积水池法 [0006] 2, a bulky pool Method

[0007] 以一定体积(超出测井仪器有效探测范围,一般半径大于5米)的水池盛有一定矿化度的水,由于离子导电作用可以模拟无限大介质下的某个电导率环境,可用于验证仪器的K值(仪器系数,用于完成电阻与电阻率或电导与电导率之间的换算);但这种简单体积模型装置决定了完全无法考查仪器的纵向和径向探测特性,因此对于当今主流的成像电测井仪器研发中的探测器特性验证和优化无效。 [0007] In a volume (the effective detection range exceeds the logging tool, generally greater than 5 m radius) certain pool filled with water salinity, since the ion conductivity of a conductive effect may be simulated environment infinite medium, available to verify the value of K instrument (instrument coefficients, for performing conversion between the resistance and the resistivity or conductance and conductivity); however, this simple model means determines the volume of the longitudinal and radial detection characteristics can not be fully examined the instrument, thus detectors for today's mainstream imaging research and development of electric logging tools to verify and optimize invalid.

[0008] 3、导电环方法 [0008] 3. The method of conducting ring

[0009] 采用串有阻抗元件的金属导电环是传统感应式测井仪器检查和刻度的常规方法,这种方法不属于实体物理模拟。 [0009] The series impedance element is a conductive metal ring of conventional methods conventional induction logging tool and scale inspection, this method is not a physical entity simulation. 由于是采用集中参数模拟实际地层分布参数对接收线圈的贡献,因此该方法不能用于考查仪器的纵向和径向探测特性,对于当今主流的成像电测井仪器研发中的探测器特性验证和优化无效,而且此方法不适于电极式电测井仪器。 Since the actual distribution is the use of lumped parameter simulated formation parameter contribution of the receiving coil, so that the method can not be used to examine the longitudinal and radial detection characteristics of the instrument, the detector characteristics for today's mainstream validate and optimize electrical imaging logging instrument developed in invalid, and this method is not suitable electrode type electrical logging tool.

[0010] 4、实验井法 [0010] 4, experimental wells method

[0011] 实验井一般是指有一定深度、能够提供一定的压力和温度环境、井中有典型岩性的地层(甚至已经部分下了套管),可对仪器的工作进行实验检测的非生产井;实验井对于不同和相同厂家、类型、型号的仪器间的对比和仪器稳定性的考察是有效的,因此是探测器研发后期的重要技术环节;但实验井中地层的实际参数(目的层、围岩的准确几何模型和电性参数)实际上是未知的,因此不可能对电测井尤其是电成像测井探测器的几何探测特性进行验证;实验井法应用中另一个局限是所实验的探测器实际上必须是完整的仪器,其探测器子系统(电极系,线圈系)与电子控制、信号放大、数据采集和传输系统等必须按照一定的耐温耐压标准全部成型,这对于在原始性创新研究中需要对许多不同方案进行对比验证的前期阶段实际上是不现实的。 [0011] Experimental wells generally refers to a certain depth, it is possible to provide a certain pressure and temperature environments typical wells have formation lithology (even been partially cased) may be non-producing wells for the assay of the working instrument ; same experimental wells and different manufacturers, type, and contrasts the stability of the instrument between the instrument model is valid, the detector is thus important technical aspects later developed; but the actual formation of the well test parameter (object layer, Wai exact geometry and electrical parameters of the rock) is actually unknown, it is not possible, especially for electrical logging electrically logging probe imaging geometry detection characteristics for verification; well test method is the application of a further limitation experiments detectors must actually complete instrument, which detector subsystem (electrode system, coil system) electronic control, signal amplification, data acquisition and transmission systems must all be molded in accordance with certain standard temperature and pressure, in which for early stage need to compare many different options to verify the originality of innovative research is actually unrealistic.

[0012] 总之,目前没有任何一种方法能够构建适用的电测井探测器实体物理模拟装置,这导致长期以来,采用数值模拟方法(由于研究中要把诸多复杂因素大量简化和理想化)设计的电测井探测器无法得到有效地验证和优化,限制了研发中设计水平的提升。 [0012] In short, no method capable of constructing the detector electrical logging simulation apparatus applies a physical entity, which results in a long time, by numerical simulation (study since many complex factors and make a lot simplified idealized) Design the electrical logging probe can not be effectively verified and optimized, limiting the design to enhance the research and development level. 本发明的目的即是解决这个高端电测井探测器研发中的重要技术瓶颈。 The object of the present invention is to solve important bottleneck i.e. the end of the electrically logging probe development.

[0031] 本发明实施例提供一种能够对全尺寸电测井探测器进行复杂地层测井响应测试的实体物理模拟装置,用于验证电测井探测器的理论和数值模拟结果,改进和优化探测器设计参数,该装置对于石油电法测井装备尤其是高端装备的研发具有重要实用价值。 [0031] Example embodiments of the present invention to provide a complex formation logging log the whole size of the electrical detector means responding entity physical simulation tests for the theoretical and numerical results verify logging probe, improving and optimizing detector design parameters, the device has important practical value for the oil and electric logging equipment, especially high-end equipment research and development. 本发明实施例采用亲水性高分子弹性凝胶与一定浓度的无机盐溶液配置成室温固化的不同电阻率的胶块,用于充当各种地层模块,并按照一定的工艺组装成能够模拟复杂地层(包括了上下围岩、侵入带和原状地层、井筒等)的实体物理模型。 Example elastic gel using hydrophilic polymer and a concentration of the inorganic salt solution of the present invention is configured to room temperature curable adhesive blocks of different resistivity, to act as various formation module, according to certain processes and assembled to simulate various solid physical model formation (including the upper and lower surrounding rock, and the invaded zone undisturbed formation, the wellbore and the like).

[0032] 图I为本发明实施例的基于凝胶的电测井探测器物理模拟装置的结构示意图。 [0032] Figure I a schematic structural diagram based on simulation apparatus is electrically logging probe physical gels of the present embodiments of the invention. 图I中的附图标号说明如下: Reference numerals in FIG. I is as follows:

[0039] G井孔延长部分(建议深度大于探测器1/2长度)。 [0039] G wellbore extension (suggested depths greater than 1/2 of the length of the probe).

[0040] 如图I所示,上述电测井探测器实体物理模拟装置包括:由下至上依次设置的下围岩层F、目的层(D和E)和上围岩层C,以及竖直贯穿下围岩层F、目的层(D和E)和上围岩层C的井孔B ;目的层包括由外至内依次设置的目的层原状地层E和目的层侵入带D ;其中,井孔B竖直贯穿目的层侵入带D。 [0040] FIG I in the electrically logging probe entity physical simulation apparatus comprising: sequentially arranged from bottom to top under confining formation F., Objective C rock surrounding layers (D and E) and an upper, and the vertical formation around the through-F, and C around the object rock layers (D and E) of the wellbore B; object layer comprises a layer of object E and object of the undisturbed formation layer are sequentially disposed from outside to inside the invaded zone D; wherein the well a vertical hole through the target layer B invasion zone D.

[0041] 在一个实施例中,该下围岩层、上围岩层、目的层原状地层和目的层侵入带分别具有不同的电阻率。 [0041] In one embodiment, the lower surrounding formation, the formation around the object and the object of the undisturbed formation layers with each layer having different invasion resistivity. 在另一个实施例中,该下围岩层和上围岩层具有相同的电阻率,该下围岩层、目的层原状地层和目的层侵入带分别具有不同的电阻率。 In another embodiment, the lower and upper surrounding rock formation surrounding the same resistivity, the formation surrounding the object and the object of the undisturbed formation layers with each layer having different invasion resistivity.

[0042] 在本实施例中,上述下围岩层、上围岩层、目的层原状地层和目的层侵入带分别是由不同的凝胶固化后形成,与各层相对应的凝胶是通过将亲水性高分子弹性凝胶分别与具有不同的离子浓度的无机盐溶液混合熬制后形成。 [0042] In the present embodiment, the lower enclosure formations, rock around the object layer and the object layer undisturbed formation invaded zone are formed from different gel after curing, the layers corresponding gels by the hydrophilic polymer forming the elastic gel was mixed with an inorganic salt solution having a different ion concentration brewed. [0043] 在本实施例中,所述下围岩层由具有下围岩所需电阻率的凝胶固化后形成;所述目的层原状地层由具有目的层原状地层所需电阻率的凝胶固化后形成;所述目的层侵入带由具有侵入带所需电阻率的凝胶固化后形成;所述上围岩层由具有上围岩所需电阻率的凝胶固化后形成。 [0043] In the present embodiment, the lower back is formed of the desired gel formation resistivity having cured surrounding rock; the destination gel layer undisturbed formation resistivity layer undisturbed formation object having the desired It is formed after curing; object of the invasion zone formed by the rear layer having a desired gel setting invaded zone resistivity; cured after the formation of a gel having a resistivity of surrounding rock strata surrounding the upper desired.

[0044] 可选地,在一个实施例中,上述具有下围岩所需电阻率的凝胶、具有目的层原状地层所需电阻率的凝胶、具有侵入带所需电阻率的凝胶、具有上围岩所需电阻率的凝胶分别填充有塑料微珠。 [0044] Alternatively, in one embodiment, having the above-mentioned desired resistivity Surrounding the gel, the gel object having a desired layer undisturbed formation resistivity, a gel having the desired resistivity of the invaded zone, Surrounding the gel has the desired resistivity are filled with plastic beads. 较佳地,塑料微珠的直径是O. 5mm-5mm。 Preferably, the diameter of the plastic beads is O. 5mm-5mm.

[0045] 具体地,用一定比例的亲水性高分子弹性凝胶、纯水与无机盐(即无机盐溶液)混合熬制以形成流动性凝胶,并在注入或填充过程中可选地充填塑料微珠,分次注入成型(在某一层注入后,必须等待凝固后才能注入不同电阻率的另一层,否则两层将产生不希望发生的混合),冷却固化后可获得不同电阻率的凝胶模块,用于模拟所需的目的层、侵入带和围岩等不同几何尺寸的地层。 [0045] Specifically, elastic gel with a hydrophilic polymer, a certain percentage of water and inorganic salts (i.e., inorganic salt solution) were mixed to form a flowable gel brewed, and optionally in the injection or filling process filling plastic beads, fractionated injection molding (injection after a certain layer, another layer must wait before injecting different resistivities after solidification, or else the two layers that will produce undesirable), cooled to solidify obtain different resistance gel rate module, for the purpose of simulation of the desired layer, invade the formation with different geometries and surrounding rock.

[0046] 本发明实施例中的凝胶内填充塑料微珠的原因在于,一方面能够增加模块的垂直·承压能力,另一方面通过孔隙性导电通道降低模块的导电能力,以便于模拟较高电阻率时离子浓度不至于太低而难以实现。 [0046] Examples of the causes of the gel-filled plastic beads embodiment of the present invention is that, on the one hand it can increase the vertical-bearing capacity of the module, on the other hand by reducing the conductivity module porosity conductive channels, so as to simulate more when high resistivity ion concentration will not be too difficult to achieve. 塑料微珠的直径可在O. 5〜5_之间选择,直径太大则限制导电的作用变得不明显,高电阻率模块宜选择较小直径的塑料微珠。 Diameter plastic bead may be between O. 5~5_ selected, too large a diameter limits the effect becomes inconspicuous conductive, high resistivity modules should choose a smaller diameter plastic beads. 在离子浓度一定的情况下,直径不同的微珠按照一定比例混合能够获得更高的电阻率(模拟如致密围岩层,高含油性储集层)。 Under certain circumstances the ion concentration, the microbeads of different diameters can be mixed in a proportion higher resistivity (such as simulated formation surrounding dense, high oil resistance reservoir). 作为一个举例,直径5mm的微珠占20%,直径Imm的微珠占80%。 As a way of example, beads of 5mm diameter, 20% diameter beads Imm 80%.

[0047] 可选地,在另一个实施例中,上述具有下围岩所需电阻率的凝胶、具有目的层原状地层所需电阻率的凝胶、具有侵入带所需电阻率的凝胶、具有上围岩所需电阻率的凝胶内已经分别掺入不同的无机色素,以标识模拟的层位。 [0047] Alternatively, in another embodiment, the above-mentioned gel having the desired resistivity of the rock, a desired object has a gel layer undisturbed formation resistivity and invaded zone having a desired gel resistivity Surrounding gel desired resistivity, having been on different inorganic pigments are incorporated, in order to identify horizons simulation.

[0048] 可选地,装置还可进一步包括:植入于下围岩层、目的层和上围岩层内的多个电导率探针,多个电导率探针连接数据采集系统。 [0048] Alternatively, the apparatus may further comprise: the formation around the implant at an object and an upper confining layer, a plurality of probes in the formation conductivity, the conductivity of the plurality of probes connected to a data acquisition system. 在各个所模拟的地层模块中植入若干个电导率探针,通过实时监测所模拟的地层模块电性以准确验证探测器的测量性能。 Conductivity probe implanted in each of a plurality of simulated modules formation, formation by real-time monitoring module is electrically simulated to verify accurately measure performance of the detector.

[0049] 在本实施例中,是采用亲水性高分子弹性凝胶来构建应用于电测井探测器的实体物理模拟装置。 [0049] In the present embodiment, the physical entity is constructed electrical logging simulation means is applied to the probe using elastic hydrophilic polymer gel. 利用亲水性高分子弹性凝胶与盐溶液按照一定比例配置成室温固化的不同电阻率的胶块,用于充当不同电阻率的地层模块,采用不同无机盐化合物能够获得所需的离子类型(如钠、钙、镁、钾等),不同的离子浓度(也称矿化度)可获得不同的电阻率(或电导率),通过逐步成型或组装多个胶块能够模拟不同结构、不同电性特征的复杂地层,而各胶体模块能够保持各自的电学性质,且模块间的耦合界面能够形成类似于实际渗透性地层中的离子浓度变化的界面(也称双电层)。 Elastic gel with a hydrophilic polymer with a salt solution, room temperature curing adhesive arranged blocks of different resistivity certain proportion, to act as the resistivity of the formation of different modules, different inorganic compound can be obtained the desired type of ion ( such as sodium, calcium, magnesium, potassium, etc.), the different ion concentration (also referred salinity) to obtain different resistivity (or conductivity), or by assembling a plurality of incremental forming bun can simulate different structures, different electrical complex formation characteristics, and each module is able to maintain their colloidal electrical properties, and is coupled between the interface modules ion concentration can be formed similar to the actual change in the permeability of the formation interface (also called an electric double layer). 因此,能够较真实的定量化模拟实际复杂地层是本发明的关键创新所在。 Accordingly, a more realistic simulation of the actual quantification of complex formation is the key innovations of the present invention resides.

[0050] 在本实施例中,由于亲水性高分子弹性凝胶的机械强度并不高,在使用中应采用带有准确定位性能的起吊装置吊装所实验的探测器,探测器底部加有适当配重以保证在物理模拟装置的“井筒”内居中并稳定。 [0050] In the present embodiment, since the mechanical strength of the hydrophilic polymer elastic gel is not high, in use, the detector should be positioned accurately with a lifting means lifting the performance of the test, the bottom of the probe plus appropriate weights to ensure the stability and centering "wellbore" physical simulation device.

[0051] 如果探测器下方还有与探测器本身无直接关系的部件(如电子短节),该模拟装置中心下方还需要预留与井眼尺寸相当的洞穴(俗称鼠洞,为图I中模拟装置下部用虚线构出的圆柱体G)。 [0051] If there is beneath the detector and the detector itself is not directly related components (e.g., electronic short section), below the center of the analog device need to reserve a size comparable with the borehole cave (commonly known mousehole, I in FIG. a lower portion of the simulation apparatus with a broken line cylinder configuration G). 在一实施例中,鼠洞G是属于模拟装置的一部分,这部分的作用就是为了使得探测器能够处于模拟地层中,探测器下部的电子短节等部件可处于该洞穴中。 In one embodiment, it is part of the mousehole G simulation apparatus, this part of the action so that the detector is able to simulate the formation in electronic components such as short section in the lower portion of the probe may cave. G部分就是在模拟装置的下部设置的与井孔相连的洞穴,直径与井孔的直径完全相同。 G cave part is connected to the wellbore lower portion of the simulation apparatus, the same as the diameter of the diameter of the wellbore. 建议留有鼠洞,这样缓慢提升或降下探测器能够准确模拟通过地层界面时的信号动态响应过程,这对于探测器性能的验证往往是需要的。 Recommended mousehole left, slowly lift or lower this detector can accurately simulate the dynamic response of the interface signal through the formation, to verify that the performance of the detector is often required.

[0052] 本发明中模型的结构是轴对称的(即可以用柱坐标系来描述)。 [0052] In the present invention, the structural model is axisymmetric (i.e., can be described in cylindrical coordinates). 当井孔以倾斜方式“插入”地层时,就形成了能够模拟更复杂地层的条件。 When the well bore in an inclined manner "Insert" floor, is formed to simulate more complex formation conditions. 也即采用适当工艺可以模拟倾斜井眼下的复杂地层,能够对三分量感应测井探测器和非推靠式方位阵列侧向测井探测器等类型的高端三维成像测井探测器进行非常关键性的复杂响应验证也是本发明能够进一步延伸的方法。 That process may be simulated using appropriate wells complex formation now inclined, it is possible for the three-component induction logging probe and non-critical pushed against a very high three-dimensional imaging detector logging formula orientation detectors array laterolog type the verification method is the complex response of the present invention can be further extended.

[0073] 进一步地,该方法还包括如下步骤:在所述具有下围岩所需电阻率的凝胶、具有目的层原状地层所需电阻率的凝胶、具有侵入带所需电阻率的凝胶、具有上围岩所需电阻率的凝胶的形成过程中,分别向各凝胶掺入塑料微珠。 [0073] Preferably, the method further comprising the step of: having the gel surrounding rock resistivity desired, the desired object has a gel layer undisturbed formation resistivity and invaded zone condensate having the desired resistivity the formation of gel, a gel having the desired resistivity of the surrounding rock, are each incorporated in a plastic gel microbeads. 可选地,所述塑料微珠的直径是O. 5-5mm。 Alternatively, the diameter of the plastic beads is O. 5-5mm.

[0076] 需要说明的是:不同的凝胶其混合水的比例、固化温度、强度等均不相同。 [0076] Note that: the ratio of different gels which mixed water, curing temperature, not the same strength. 这是具体工艺和材料问题,其参数变化范围、操作的容许范围非常大,而且是与本发明的实质内容无关,无须具体说明或细化限定。 It is the particular process and materials issues, the parameters of range, the allowable range of operation is very large, and is irrelevant to the substance of the present invention, no detailed description is defined or refined. 本发明的创新思想的实质是:通过形成并保持着不同离子浓度的凝胶块来模拟不同电阻率的各种地层的组合(这也正是现有的各种方法都没有很好做到的-如本发明背景技术的记载);本发明上述涉及的“规定温度”、“一定温度”、“一定比例”是作为工艺方面的说明,仅仅是一种提示,在实际应用可根据工艺及材料进行调整。 Essence of the innovative ideas of the present invention are: to simulate the various combinations of various formation resistivity by forming and maintaining different ion concentrations gel mass (which is the conventional various methods are not well done - as described in the background art of the present invention); the present invention relates to the above "predetermined temperature", "certain temperature", "a certain proportion" aspect of the process as described, is only a hint, according to the practical application of the processes and materials to adjust.

[0077] 进一步地,该方法还可以包括如下步骤:在所述承载容器的两侧设置两个板状电极,分别作为电极式电测井探测器的B电极和N电极。 [0077] Further, the method may further comprise the step of: two plate electrodes arranged at both sides of the carrier container, respectively, as B-type electrode and the N electrode electrically logging probe. 具体地,在承载容器两侧放置两个表面积不小于O. Im2板状电极,分别作为电极式(电流聚焦)电测井探测器的B电极(屏流回路电极)和N电极(主电流回路电极),这些电极对线圈式电测井探测器无作用也无影响。 In particular, two placed on either side of the carrier surface area is not less than O. Im2 container-shaped electrodes were used as electrodes of formula (current focus) B logging probe electrode (screen flow circuit electrode) and the N-electrode (main current circuit electrode), these electrodes have no effect and no effect on the electrical logging detector coils. [0078] 进一步地,该方法还包括如下步骤:将充当井筒的充水容器(即井筒容器)中的水抽去使井筒容器能够取出,并将该部分体积注入所需电阻率的一定离子浓度的水充当井液。 [0078] Preferably, the method further comprising the steps of: filling the water container will act wellbore (i.e., a wellbore vessel) take away the water container can be taken out wellbore, and the portion into a certain volume resistivity desired ion concentration the water acts as a well fluid. 井筒几何上是轴对称的,中空的部分充填井液(也是离子水溶液),被凝胶模拟的地层包裹(即所谓的承载)。 Axisymmetric geometry of the borehole, well fluid filling the hollow portions (and ion aqueous solution), gel-formation package was modeled (i.e., a so-called carrier).

[0079] 进一步地,该方法还包括如下步骤:各模块“浇筑”时,需要在接近模块的外缘对称放置数个(3个或以上即可)电导率探针;这种探针采用双极四线方式(一对电流回路和一对电压回路,分别接屏蔽双绞线后再整体缠绕后引出),探针电极的背面绝缘以减少外侧导电的影响;工作时这些探针接至数据采集系统用于实时监测模块电导率,可以校正温度、时变等对探测器测量参数的影响,使物理模拟结果准确可靠。 [0079] Preferably, the method further comprising the step of: when each module "pouring", symmetrically placed required number (three or more to) conductivity probe near the outer edge of the module; this double probe four-wire electrode (a pair of a pair of voltage and current loop circuit, respectively, then the entire lead-shielded twisted before winding), the back surface of the probe electrode insulated to reduce the effects of lateral conductive; probes connected to the working data acquisition system for real-time monitoring module conductivity, the temperature can be corrected, the effect on the detector measures the time-varying parameters of the physical simulation is accurate and reliable results.

[0080] 至此,本发明的一个典型实施过程完成。 [0080] Thus, an exemplary embodiment of the present invention is completed. 由于亲水性高分子弹性凝胶的机械强度并不高,在使用中应采用带有准确定位性能的起吊装置吊装所实验的探测器,探测器底部加有适当配重以保证在物理模拟装置的“井筒”内居中并稳定。 Since the mechanical strength of the hydrophilic polymer elastic gel is not high, in use, the detector should be positioned accurately with a lifting means lifting the performance of the test, the bottom of the probe plus the appropriate weight to ensure the physical simulation apparatus in the "Shaft" is centered and stable.

[0081] 如果探测器下方还有与探测器本身无直接关系的部件(如电子短节),本方法所述的装置中心下方还需要预留与井眼尺寸相当的洞穴(俗称鼠洞,图I中模拟装置下部用虚线构出的圆柱体)。 [0081] If there is beneath the detector and the detector itself is not directly related components (e.g., electronic short section) below the center of the device according to the present method further need to reserve a size comparable with the borehole cave (commonly known mousehole, FIG. I analog in lower portions of the cylinder structure by a dotted line). 建议留有鼠洞,这样缓慢提升或降下探测器能够准确模拟通过地层界面时的信号动态响应过程,这对于探测器性能的验证往往是需要的。 Recommended mousehole left, slowly lift or lower this detector can accurately simulate the dynamic response of the interface signal through the formation, to verify that the performance of the detector is often required.

[0082] 在各层溶胶“浇筑”的过程中,层间的融合和渗透是允许的,且对于真实的模拟地层是有益的。 [0082] In each layer the sol "pouring" in the process, fusion and penetration between the layers is permitted, and is beneficial for the realistic simulation of the formation. 模型在制造尺寸上的一定误差(如不大于±3cm)所造成的影响(对径向和纵向响应特征)是完全可以忽略的,因为任何电测井探测器本身的测量精确度和空间分辨率并不高,相对误差通常在±29TlO% (在测量动态范围的两端误差甚至还要大得多)。 Effect size in the manufacturing model certain errors (such as not greater than ± 3cm) caused by the (radial and longitudinal response characteristics) is completely negligible, since no electrically logging probe measurement accuracy and spatial resolution itself is not high, usually relative error (the measurement error of both ends of the dynamic range is even larger) at ± 29TlO%.

[0083] 本发明的方法实施例的优点在于:通过该方法形成的装置能够方便的模拟各种不同地层尺寸和导电特性。 Advantage of embodiments of the method [0083] of the present invention is: formed by means of the method can be easily ground to simulate a variety of different sizes and electrically conductive properties. 本发明所述的实体物理模拟装置,采用亲水性高分子弹性凝胶作为模拟地层模块的关键性材料,该装置能够用于对全尺寸电测井探测器的物理模拟,可用于验证包括纵向、径向探测特性,测量精度,纵向分辨率在内的探测器测井响应特性。 Physical entity simulation apparatus according to the present invention, a hydrophilic polymer gel elasticity module is an analog ground critical materials, the device can be used to simulate a full-size physical electrical logging probe, it can be used for verifying comprises longitudinal radial detection characteristics, measurement accuracy, including probe vertical resolution log response characteristic.
