| 摘 要： | 在砂泥岩地层中自然电位的影响因素主要有地层水矿化度与泥浆矿化度差异、泥质含量、含水饱和度、地层温度和地层厚度。有些公司提供了自然电位受温度和地层厚度的校正图版,但没有考虑泥浆冲洗深度、侵入深度和束缚水饱和度大小对自然电位的影响。充分借鉴了前人的研究成果,结合双水饱和度模型重新构造了砂泥岩中自然电位的响应方程。用新构造的方程计算的地层水电阻率数值与测试得到的地层水电阻率数值非常接近。

| Abstract: | The main factors of spontaneous potential includes the differences size of between formation water salinity and mud salinity, clay content, water saturation in pore, formation temperature and formation thickness in sand?shale formations. Some companies offer the correction charts of spontaneous potential about temperature and thickness of stratigraphic, but did not consider the mud invasion depth and bound water saturation. the paper reconstruct the spontaneous potential of sand-shale formation response equation by according to predecessor test results and dual water saturation model, the formation water resistivity values by the new equation calculated and the formation water resistivity value by tested is very close. |
