神狐海域天然气水合物智能拟合建模与开采研究

Study on intelligent fitting modeling and exploitation of natural gas hydrate in the Shenhu area

摘要:

中国南海神狐海域水合物储层地质特征复杂，难以获取储层全部参数。本研究通过智能拟合手段，根据实际试采产气量拟合选择南海神狐海域作为目标区域，降压开采，结合垂直井网开采措施，提升开采效果，解决我国未来的能源紧缺问题。由于南海神狐海域水合物储层参数缺少数值模拟所需的精确值，通过历史拟合方法确定储层物性参数，并进行长期开采预测，为后续水合物开采实验做铺垫。

Abstract:

It is difficult to obtain all reservoir parameters due to complicate geological characteristics of the hydrate reservoir in the Shenhu area， South China Sea. In this study， by means of intelligent fitting， according to the actual gas yield in the trial production， the Shenhu Sea area in the South China Sea was selected as the target area， and depressurization mining was combined with vertical well network mining measures to improve the mining effect so as to solve the problem of energy shortage in China in the future. Due to the lack of precise values required for numerical simulation of hydrate reservoir parameters in the Shenhu area of the South China Sea， the reservoir physical property parameters were determined by the historical fitting method and long-term exploitation prediction was carried out to lay a foundation for subsequent hydrate exploitation experiments.
