Rapid solution construction method for rock salt cavity

一种快速溶解的盐岩溶腔建造方法

Abstract

一种快速溶解的盐岩溶腔建造方法,属于盐类矿床水溶开采及盐岩溶腔储库控制溶解建造范畴。其特征在于具体步骤为:(1)从地表钻单井至目标矿床;(2)根据常规方法对管串系统安设完成之后,即可通过注出水管串系统进行正反循环溶解建腔;(3)在注出水正反循环溶解建腔过程中,根据腔体大小尺寸变化,适时调整注出水管柱位置及其间距,使腔壁附近流体运移速度及盐岩溶解速度达到最高。本发明科学调整注出水管柱位置及间距,依此提高腔壁附近溶液对流扩散速度,进而提高盐岩溶解及腔体建造速度,达到盐岩资源经济开采、盐岩溶腔高效快速低成本建造的目的。该方法是盐矿高效开采及盐岩溶腔储库快速溶解建造的理想方法。
The invention relates to a rapid solution construction method for a rock salt cavity, belonging to the field of salt deposit solution mining and rock salt cavity reservoir controlled solution construction. The method is characterized in that the method comprises the following steps that: (1) a single well is drilled from ground to a target deposit; (2) after a pipe string system is installed according a conventional method, direct and reverse circulating solution can be conducted to construct a cavity through a water filling pipe string system and a water draining pipe string system; and (3) in the process of direct and reverse circulating solution to construct the cavity through water filling and water draining, according to the variation of the size and the dimension of the cavity, the positions of water filling pipe columns and water draining pipe columns and the spacing thereof are adjusted in time to keep the migration velocity of fluid near the wall of the cavity and the rock salt solution velocity to be highest. Since the positions of water filling pipe columns and water draining pipe columns and the spacing thereof are scientifically adjusted to increase the convective diffusion velocity of solution near the wall of the cavity and to further increase the rock salt solution velocity and the cavity construction velocity, the goals of economic rock salt resource mining and high-efficiency rapid low-cost rock salt cavity construction are reached. The method is an ideal method for high-efficiency mining of rock salt and rapid solution construction of rock salt cavity reservoirs.
