On Sand Production Log Evaluation of High-pressure Gas Reservoir in Tarim Basin
摘要
Abstract
Dabeikeshen of Tarim oilfield is characterized with ultra deep wells, high temperature and high pressure. The sand production in the process of well testing in this area seriously influences the process of formation testing, pilot production and reservoir evaluation. Introduced is sand production mechanism in the pay zones. It is believed that the main reason for formation sand production in compact and stabilized deep reservoir should be over-loaded differential pressure and faster production speed, which can lead to rock shear fractures or tension fractures. On the basis of rock mechanical parameters, reservoir pressure and ground stress calculated by well logging data, established are the critical production differential pressure computation models for barefoot well completion, perforation well completion and for that based on rock's uniaxial com-pressive strength. Pay zone sand production condition is predicted by combining following methods: the sand index method, the critical production differential pressure method and the grey correlation statistical analysis method, and so on. The production differential pressure is calculated rapidly and accurately withlogging data. The study is helpful in quantitatively analyzing sand production and determining optimum well completion scheme, and provides foundation for reservoir sand control decision making.关键词
