在油气勘探工作中,油气层压力的预测和控制直接关系到钻井的成功率和油气田的勘探速度等问题。压力录井的方法可进行地层压力预测,有益于安全快速钻进。异常地层压力成因多样,随钻表现各不相同,灵活掌握运用检测方法,能有效捕捉信息,准确判断压力情况。dc指数和气体参数法是应用较多的地层压力检测方法,在钻达高压油气层之前,能预测异常高压的存在并对井控提供有效的技术支持。认真总结经验,抓住主要矛盾,仔细工作,完全可以作好地层压力预测工作。
In the oil and gas exploration, the prediction and control of the reservoir pressure has a direct bearing on the success rate of drilling and the exploration speed of oil and gas fields. The pressure logging method can predict formation pressure and is beneficial for safe and rapid drilling. Abnormal formation of pressure causes a variety of, while drilling performance vary, flexible use of detection methods, can effectively capture the information accurately determine the pressure situation. The dc index and gas parameter method are the most widely used methods of formation pressure detection. Before drilling high-pressure reservoirs, they can predict the existence of abnormal high pressure and provide effective technical support for well control. Conscientiously sum up experience, seize the main contradictions, careful work, can do a good job in predicting formation pressure.
