近来我国发现了许多碳酸盐岩裂缝性油气藏。为了增产的需要,在开发过程中广泛使用了压裂和酸化技术。但是相应的理论研究工作至今还是不多的。为了提高我国压裂酸化科学技术水平,我们分析了国外有关科研成果,结合四川阳新灰岩具体条件,进行了理论和实验研究。具体内容有:吸收国外一般理论研究成果,建立了酸沿裂缝稳定层流运动的对流扩散方程式;整理了国外利用电子计算机求解方程式的计算结果,建立了
Recently, many carbonate fractured reservoirs have been discovered in our country. In order to increase the production needs, the fracturing and acidizing technologies are widely used in the development process. However, the corresponding theoretical research is still not much. In order to improve the scientific and technological level of fracturing and acidizing in our country, we have analyzed the relevant scientific research abroad, combined with the specific conditions of Yangxin limestone in Sichuan, conducted theoretical and experimental research. The concrete contents are as follows: absorbing the research results of general theories in foreign countries, establishing the convective and diffusive equations for the steady laminar laminar motions of acid along fractures; sorting out the computational results obtained by using electronic computers abroad to solve the equations and establishing
