Biography
Haifa Tang has her expertise in oil and gas production in development geology. Horizontal well is the key technology to develop such tight gas field, and the practice has proven its advantage in improving single well production. But as a whole, whether the horizontal well enhance the recovery efficiency of gas field or not is still a controversy because of the vertical sparse distribution of profit plays. In solving such problem, he presents a new concept of concentration ratio of the vertical profile reserves. And on the basis of this concept, three sand body distribution models have been established. They are single thick block type, multi period vertical overlap pan connected type, and multi period dispersed partially connected type. Reservoir recovery of horizontal well under different sand body combination has been studied, and technical measures to improve the recovery rate of horizontal wells have been proposed.
