摘要

摘要: 与国内外大型缝洞型碳酸盐岩储层不同，冀中坳陷廊固凹陷北部杨税务潜山具有储层埋藏深、温度高、低渗致密、储集空间复杂，非均质性强等特征，酸压改造成为提高单井产量的必备技术，但由于岩性和裂缝发育的不同，酸岩反应特征复杂，储层酸压改造设计针对性差。针对杨税务潜山峰峰组、上马家沟、下马家沟、亮甲山四套储层特征，开展酸岩反应主控因素研究，建立不同储层类型的酸岩反应动力学方程，根据酸岩反应实验与裂缝导流能力评价，提出四套储层的个性化酸液配方及改造对策，指导了区块13井次的高效改造，为亿吨级储量动用提供了技术保障，也为国内类似基质裂缝型碳酸盐岩的储层改造方案设计提供了技术借鉴。

Abstract: Different from the domestic and overseas large seam hole type carbonate reservoir, northern Langgu depression Yangshuiwu buried hill in Jizhong depression has its own unique characters such as high buried depth, high temperature, low permeability, dense reservoir spaces and strong heterogeneity. Under those circumstances, fracturing acidizing transformation became the necessary technology in order to improve the single well production but it still has shortcomings like poor pertinence due to the different lithology and fracture development, complex acid-rock reaction.From the analyses of the reservoir characters of Yangshuiwu buried hill fengfeng group, upper majiagou group, lower majiagou group, and liangjiashan group, this essay carried out the study on acid rock reaction controlling factors, build up acid-rock reaction kinetics equation in different types of reservoirs. According to the results of acid-rock reaction experiment and fracture conductivity evaluation, this essay put forward personalized acid fluid formula and countermeasures of the above four sets of reservoirs. It has efficiently guided the reconstruction of 13 Wells in those blocks. Beside providing a technical support for the use of reservoirs in 100-million-ton scales, this essay also provided a reference for the design of the similar matrix of fractured carbonate rock reservoir reconstruction in domestic field.
