神泉构造位于吐哈盆地台北凹陷西部的胜南构造带。胜南构造带是在燕山期古隆起上发育的低幅构造,紧邻胜南、胜北次凹,具有有利的生、储、盖条件。神泉地区的地震勘探工作开始于1986年,通过二维地震解释发现了神泉潜伏构造。在地层精细划分对比过程中,首先要确立岩性和电性对比的主要标志和次级标志。主要标志层在纵向上有一定的厚度,平面上分布相对稳定,电性特征明显,一般为大的湖侵形成的泥岩。次级标志层与主要标志层有近似的特征,但平面分布稍欠稳定,一般为次级湖侵形成的泥岩。神泉矿区多数井均有比较明显的标志层,对比过程中再配以岩电组合曲线特征(主要是自然伽玛、自然电位、声波时差、4m电阻率、深侧向曲线),从而实现全区地层的精细对比。
Shenquan structure located in the Turpan-Hami basin in western Taibei depression Shengnan structural belt. The Shengnan structural belt is a low-profile structure developed on the paleohigh uplift of the Yanshanian period and is located close to the Shengnan and Shengbei sub-concavities. It has favorable conditions for raw, reservoir and captivity. Seismic exploration in the Shinsen area began in 1986 and revealed the Shinsen latent structure through 2D seismic interpretation. Fine stratigraphic division in the process of contrast, we must first establish the lithology and electricity contrast the main signs and secondary signs. The main sign layer has a certain thickness in the vertical direction, the distribution is relatively stable in the plane, and the electrical characteristics are obvious. Generally, mudflats formed by large lake invasion are formed. The secondary marker layer has similar characteristics to the major marker layers, but the plane distribution is less stable, generally mudstone formed by secondary lake invasion. Most of the wells in the Shenquan area have obvious sign layers, which are matched with the characteristics of the rock-electric composite curve (mainly natural gamma ray, natural potential, acoustic time difference, 4m resistivity and deep lateral curve) in the comparison process, Fine contrast of strata.
