陕北黄土塬地区油田注水工程水文地质勘查研究
|
摘要
陕北地区水源匮乏严重制约了当地油田的注水开发。为解决油田注水工程水源不足的问题,采用水文地质调查、钻探、坑探、抽水试验、水质检测和测流等一系列方法,查明了注水工程水源地附近的水文地质条件,确定了陕北油区潜水含水岩组的岩性、厚度、富水性及潜水的补给、径流、排泄条件、地下水动态特征、开采条件及水化学等特征,明确了油区集中供水水源地的位置及取水工程类型并预测集水构筑物水质水量及开采保证程度。此次研究也为其他油田解决集中供水水源地勘察问题提供一定的参考依据。
The water shortage in the north of Shaanxi province seriously restricts the development of water injection in the local oilfield. In order to solve the problem of water shortage in oilfield's water injection project,a series of methods,such as hydrogeological investigation,drilling,test pitting,pumping test,water quality detection and flow measurement,were used to find out the hydrogeological conditions near the water source area of water injection project,and to determine the characteristics of lithology,thickness,water yield property,phreatic recharge,runoff,drainage,groundwater dynamic characteristics,mining conditions and water chemistry in the north Shaanxi oil region,and to make clear the location of centralized water supply sources and the water intake project types and to predicte the water content and water quality of catchment build and exploitation- guarantee degree. This study also provides a reference for other oil field to solve the problem of the water source prospecting.
