摘 要: | 深层、低渗透油藏由于其埋藏深、物性差,开发效果较差,特别是中后期随着地层能量的亏空严重,开发效果会进一步变差。本文应用层序地层学理论与方法,建立沉积微相的空间展布特征,预测砂体分布,应用数值模拟技术对剩余油的分布进行研究,选取实验井组进行试注的方法对夏70块深层低渗油藏的注水可行性进行论证,实施注水水质改性、严格的油层保护等手段,取得了较好的开发效果和显著经济效益,实现深层低渗油田开发的良性循环。

Matching Technology Research and Application of the Deep-seated and Low-Permeability Reservoir during the Medium-Later Development Period |
| |
Abstract: | The development effective of the deep--seated and low--permeability reservoir is not good because of its deep burial depth and poor physical characteristic, especially during the medium-later development period when the formation energy decreases seriously. This paper has been built the space distribution characteristic of microfacies, and described the sand distribution with the theory and methods of formation sequence. The research of remaining oil distribution has been developed with reservoir numerical simulation. The injection possibility of deep-seated and low-permeability reservoir has been developed in Xia 70 fault-block reservoir, by choosing the experimental wells as injection test. The water quality of injected water has been developed largely and the reservoir has been protected strictly. The development effect is better and economic effect is larger. And the good circulation of the deep-seated and low-permeability reservoir has been realized. |
