摘要
屏蔽暂堵技术是防止入井流体固相和液相侵入储层的最有效方法之一。在实际应用中 ,由于缺乏确定储层孔隙体积、暂堵剂颗粒大小和分布的测定以及定量计算方法 ,使得屏蔽暂堵技术的使用仍然处于非定量化阶段。为了减小对储层的伤害 ,特别是对低渗气藏的伤害 ,有必要对屏蔽暂堵技术进行深入研究。文章简要介绍了屏蔽暂堵定量计算和应用方法 ,其中包括 :屏蔽暂堵分形理论的主要内容 ,分维数的计算 ,确定岩样孔隙体积以及暂堵剂颗粒大小和分布的实用方法。还探讨了在使用过程中可能遇到的不满足单纯分形情况的储层 ,并给出了相应的确定孔隙分布及暂堵方案等方法。
The temporary plugging technique is one of the most effective methods for preventing the solid and liquid phases in well invading the reservoir.In the practice,the application of the temporary plugging technique is still in unquantized stage due to lack of the methods for determining reservoir′s pore volume and the size and distribution of the temporary plugging agent particles,as well as the quantitative calculation.In order to reduce the damage to reservoir,especially to low-permeability reservoir,it is necessary to make a thorough study of the temporary plugging technique.In this paper,the authors briefly present the quantitative calculation and application of the temporary plugging technique,including the major content of the temporary plugging fractal theory,the calculation of the fractal dimension and the determination of the rock sample′s pore volume and the size and distribution of the temporary plugging agent particle.The authors also discuss the reservoirs that can not satisfy the simple fractionization and that may be met in the application of this technique and give out the methods for determining the pore distribution and temporary plugging plan.
