[0035] 三、按地层岩性原则划分,对所绘制的空间分布图的地层进行整合。 [0035] Third, the principle of division by formation lithology, the formation of the spatial map drawn distribution integration. 具体实施步骤如下: DETAILED DESCRIPTION steps:

[0036] 地层岩性原则是指根据地层岩性特征将相邻且岩性相似的地层划分为同一层,将相邻但岩性不同的地层划归为不同层;地层岩性分为砂土类和粘土类地层,其中砂土类地层主要包括砂砾层、粗砂层、中砂层、粉砂层及粘土质砂(砾)层等以砂(砾)质为主的地层,粘土类地层主要包括粘土层、砂(砾)质粘土层等以粘土为主的地层。 [0036] The principle is that the formation lithology lithology and formation lithology adjacent stratigraphic division similar to the same layer, adjacent but different lithostratigraphic classified as different layers; divided sand lithology class and clay formation, wherein the formation sand based mainly comprising sand (gravel) mass formation based gravel, coarse sand layer, the sand, silt and clay layers sand (gravel) layer or the like clay formation including mainly clay strata clay, sand (gravel) clay layer or the like.

[0037] 如图3所示(图3中各序号代表内容与图2相同),通过分析各地层的岩性及层位关系,按照地层岩性原则划分,可将图3中3和4、7和8、9和10、13和14分别整合为201、202、203、204。 [0037] (each number representing a content of the same in FIG. FIG. 32) shown in Figure 3, by analyzing the relationship between the lithology and horizon around the layer, divided in accordance with the principles of formation lithology may be 3 and 4 in FIG. 3, 7 and 8, 9 and 10, 13 and 14 are integrated into 201, 202. 其中,201为细砂粉砂互层,厚度3.20m ;202为粘土与砂质粘土互层,厚度5.92m ;203为中砂与粘土质砂互层,厚度5.43m ;204为砂烁质粘土与粘土互层,厚度 Wherein 201 is interbedded sand silt, the thickness of 3.20m; 202 clay and sandy clay interbedded thickness of 5.92m; 203 to clayey sand with interbedded sand, the thickness of 5.43m; 204 bright clay to sand interaction with the clay layer, the thickness of

2.43m。 2.43m. 按照地层岩性原则进行整合划分后,地层自上而下分别为1、2、201、5、6、202、203、 After integration of divided according to the principles of the formation lithology, top to bottom are 1,2,201,5,6,202,203 formation,

11、12、204,其特征在于将第四系下部地层划分为粘土类地层与砂土类地层相间沉积的组合结构,其划分结果如图4所示(图中左侧序号为粘土类地层,右侧序号为砂土类地层)。 11,12,204, characterized in that the lower portion is divided into a fourth strata of sand and clay formations spaced stratigraphic deposited composite structure, which results of divisions shown (left side in FIG clay strata Nos. 4, right sand stratigraphic sequence number).

[0038] 四、在上述步骤三的基础上,再进行地层厚度原则划分,按地层厚度从薄到厚的顺序依次划分,具体划分原则如下: [0038] Fourth, based on the above-described step III, and then dividing the thickness of the principle of formation, turn divided by bed thickness from thin to thick sequence, specific division following principles:

[0039] A、厚度小于0.50m的地层,不满足单独分层,厚度及岩性忽略不计。 [0039] A, layer thickness of less than 0.50m, and does not satisfy the individual layered, thickness and lithology negligible.

[0040] B、对于厚度在0.50〜1.50m范围内的地层,若该地层厚度与其上、下相邻地层的厚度之和的比值小于1/10,则该地层与上、下相邻地层划归为同一层;若该地层厚度与其上、下相邻地层的厚度之和的比值为1/10〜1/4,则该地层厚度及岩性忽略不计;若该地层厚度与其上、下相邻地层的厚度之和的比值大于1/4,则该地层宜单独分层。 Ratio [0040] B, for the formation in the thickness range 0.50~1.50m, if the thickness of the formation thereon, the thickness of the adjacent formations and is less than 1/10, then the formation of the upper and lower strata adjacent draw classified as the same layer; if the layer thickness of its upper, lower and the ratio of the thickness of the formation adjacent to 1 / 10~1 / 4, the thickness and lithology of the formation is negligible; if the thickness of its formation, the lower phase and the formation of o-thickness ratio greater than 1/4, the desirable individual layered formation.

[0041] C、厚度在大于1.50小于或等于2.50m范围内的地层,若该地层厚度与其上、下相邻地层的厚度之和的比值小于或等于1/10,则该地层与上、下相邻地层划归为同一层;若该地层厚度与其上、下相邻地层的厚度之和的比值为1/10〜1/6,则该地层厚度及岩性忽略不计;若该地层厚度与其上、下相邻地层的厚度之和的比值大于1/6,则该地层宜单独分层O [0041] C, a thickness of greater than 1.50 or less within the formation range of 2.50m, if the thickness of the formation thereon, and the thickness of the lower layer adjacent the ratio of 1/10 or less, the formation of the upper and lower classified as the same layer as the adjacent formation; if the layer thickness of its upper, lower and the ratio of the thickness of the formation adjacent to 1 / 10~1 / 6, the thickness and lithology of the formation is negligible; if the thickness of its layer ratio, the lower the thickness of the adjacent formations and greater than 1/6, the desirable layered formation alone O

[0042] D、对于厚度大于2.5m的地层,可单独分层。 [0042] D, for the formation of a thickness greater than 2.5m, may be layered separately.

[0043] 按照地层厚度划分原则,对所绘制的空间分布图的地层进行整合,按地层厚度从薄到厚的顺序依次划分的具体实施步骤如下: [0043] division according to the principle of formation thickness, plotted on the spatial distribution of the formation of FIG integration, by formation thickness from thin to thick in the order of the divided specific implementation steps are as follows:

[0044] a、图4中地层2厚度最薄,其厚度小于0.50m,按照厚度划分原则A,该层厚度及岩性忽略。 [0044] a, layer 2 in FIG. 4 the thickness of the thinnest thickness of less than 0.50m, the thickness of the division in accordance with the principles of A, the layer thickness and lithology ignored. 因此,I和201划归为同一层101,其厚度为I和201之和,即9.13m,属于砂土类地层O Thus, 201 I and 101 classified as the same layer, and a thickness of 201 I sum, i.e. 9.13m, belonging to the class of the formation sand O

[0045] b、图4中厚度对于厚度在0.50〜1.50m范围内的地层有6,由于该地层厚度与其上、下相邻地层(5和202)的厚度之和的比值约为0.105,其值介于1/10〜1/4之间。 [0045] b, the thickness of the layer 4 to a thickness in the range 0.50~1.50m 6, since the thickness of the formation thereon, and the thickness of the lower layer (5, 202) adjacent the ratio of approximately 0.105, which value is between 1 / 10~1 / 4. 因此,按照厚度划分原则B,该地层厚度及岩性厚度忽略不计,即5和202划归为同一层102,其厚度为两地层之和,为12.37m,属于粘土类地层。 Thus, according to the thickness of the principle of classification B, thickness and lithology of the formation is negligible thickness, i.e., 5 202 and 102 under the same layer, a thickness of the sum of two strata, is 12.37m, belonging clay formation.

[0046] c、图4中厚度介于大于1.50小于或等于2.50m之间的地层有12和204,由于12较204厚度小,按照先薄再厚的原则,先分析地层12,12的厚度与上、下相邻地层(11和204)的厚度之和的比值约为0.38,其值大于1/6。 [0046] c, in a thickness of between 4 equal to or greater than 1.50 less than 2.50m formation between 12 and 204, 204 due to the relatively small thickness of 12, according to the principle first thin and then thick, the thickness of the layer 12, 12 of the first analysis and upper, lower and the thickness of the layer (11 and 204) adjacent the ratio of about 0.38, which is greater than 1/6. 因此,按照厚度划分原则(3),该层可单独分层,属砂土类地层。 Thus, according to the principle of dividing a thickness (3), the layer can be layered separately, is based sand formations.

[0047] d、对于地层203、11的厚度均大于2.50m,均单独分层;对于204位于最底层厚度为2.43m接近于2.50m,且其上部12满足单独分层的标准,因此,204也可单独分层。 [0047] d, the thickness of the formation is greater than 2.50m 203,11, are layered separately; for a thickness of 204 at the bottom layer close to 2.50m 2.43m, and its upper 12 to meet individual layered standard, therefore, 204 It may be layered separately.
