摘要/Abstract

摘要： 针对PVT实验一致性检验方法不适用于高温油藏的问题,提出了一种针对高温油气藏相态实验结果一致性的系统检验方法,该方法通过使用高温平衡常数计算法对物质平衡法、Hoffman法进行修正,并综合两者与组分校验法对相态实验的组分数据以及定容衰竭实验数据进行一致性检验,可以更准确地判断实验结果。选取塔里木油田博孜104凝析气样品A和博孜7井区挥发油样品B 2个高温油气藏流体的组分数据与定容衰竭实验数据开展一致性检验,其结果验证了文中方法的有效性和可靠性。该研究对于明确高温下地层油气特别是挥发油和凝析气的相态特征具有重要意义。

Abstract: Since the PVT test consistency test method is inapplicable to high-temperature reservoirs, a systematic test method was proposed for the consistency of phase state test results in high-temperature hydrocarbon reservoirs, in which the equilibrium constant calculation method at high temperature was used to modify the material balance method, Hoffman method and equilibrium constant method, and to test the consistency between the component data of the phase state test and the constant-volume depletion test data with such two methods and the component verification method, so as to judge the test results more accurately. A consistency test was conducted between the component data and the constant-volume depletion test data of two fluid samples taken from high-temperature hydrocarbon reservoir, namely Condensate Gas Sample A from Well Bozi 104 and Volatile Oil Sample B from Well Bozi 7 in Tarim Oilfield. The results verified the validity and reliability of the method in this paper. This study is important to clarify the phase characteristics of formation oil and gas, especially volatile oil and condensate gas at high temperature.
