摘要

油气藏流体性质和相态预测是深层—超深层油气勘探决策、储量评估与开发方案制定的关键技术问题。然而

现有相态理论是基于中—低温压条件建立

难以适用于超高压高温油气藏。目前

深层—超深层油气相态预测多依赖于地质-地球化学方法

通过分析烃源岩在不同成熟阶段所生成烃类组分的特征来间接推断。利用超高压高温(200 MPa、200 ℃)可视化PVT(压力-体积-温度)相态分析仪

选取准噶尔盆地南缘天然气与不同类型原油

按不同气油比(GOR)配制混合物

开展油气相态演化的可视化PVT模拟

并对准噶尔盆地南缘超深层油气藏的油气相态进行实际判识。158 ℃高温条件下的实验结果表明:GOR为2 000 m

、5 000 m

和8 000 m

的凝析油与天然气混合物

在压力分别大于67 MPa、61 MPa和59 MPa时

除形成少量固相沉积外

明显呈雾状气相

而低于上述压力后转变为气-液两相

至18 MPa时析出的液态油分别占总油气体积的8.87%、2.52%和1.41%;GOR为2 000 m

、 5 000 m

和8 000 m

的轻质油与天然气混合物

在压力大于130 MPa时呈气-固两相

压力在130~90 MPa时呈气-液-固三相

压力小于90 MPa后转变为气-液两相

压力在40 MPa时析出的液态油分别占总油气体积的45%、35%和22%;GOR为8 000 m

的常规黑油与天然气混合物

在压力大于130 MPa时呈气-固两相

压力在130~90 MPa时呈气-液-固三相

压力小于90 MPa时转变为气-液两相

至30 MPa时析出的液态油约占14%。由此可见

高温条件下压力对天然气溶解原油的能力及油气相态具有强控制作用。在深层—超深层超高压高温条件下

GOR＞2 000 m

的油气藏基本为雾状气相凝析气藏。准噶尔盆地南缘地区呼探1井和天湾1井等超深层油气藏(GOR＞2 000 m

)在地层条件下均为雾状气相凝析气藏

天然

气几乎溶解了原油中绝大部分烃类

由此导致其地面凝析油的密度偏高。

Abstract

Prediction of fluid properties and phase behaviors in oil and gas reservoirs represents a critical technical challenge for deep and ultra-deep petroleum exploration decision-making

reserve estimation

and development strategy design. However

existing phase behavior theories have been established primarily under medium-to-low temperature and pressure conditions

limiting their applicability to ultra-high-pressure and high-temperature reservoirs. At present

phase behavior prediction for deep and ultra-deep reservoirs mainly relies on geological and geochemical methods

which indirectly infer phase characteristics through the analysis of hydrocarbon compositions generated from source rocks at different maturity stages. In this study

a high-pressure and high-temperature (200 MPa and 200 ℃) visual PVT phase behavior analyzer was employed. Natural gas samples and crude oils of different types from the southern margin of Junggar Basin were selected

and their mixtures were prepared at varying gas-oil ratios. Visual PVT simulations were subsequently conducted to investigate oil and gas phase behavior evolution

and the phase behaviors of ultra-deep oil and gas reservoirs in the southern margin of Junggar Basin was further identified. The experimental results at a high temperature of 158 ℃ demonstrate as follows. The condensate oil and natural gas mixtures with gas-oil ratios (GORs) of 2 000 m

5 000 m

and 8 000 m

exhibit a vaporous gas phase behavior with only minor solid deposition when the pressure exceeds 67 MPa

61 MPa and 59 MPa

respectively. As the pressure decreases below these thresholds

the systems transform into gas-liquid two-phase states. At 18 MPa

the precipitated liquid oil accounts for 8.87 %

2.52 %

and 1.41 % of the total oil-gas volume respectively depending on different GORs. The light oil and natural gas m

ixtures with GORs of 2 000 m

5 000 m

and 8 000 m

remain in a gas-solid two-phase state at pressures above 130 MPa

transition into a gas-liquid-solid three-phase state within the pressure range of 130-90 MPa

and subsequently convert into a gas-liquid two-phase state when the pressure decreases below 90 MPa. At 40 MPa

the precipitated liquid oil accounts for 45 %

35 % and 22 % of the total oil-gas volume respectively depending on different GORs. For the ordinary black oil and natural gas mixture with a GOR of 8 000 m

gas-solid two-phase state with significant solid deposition occurs above 130 MPa . Within the pressure range of 130-90 MPa

the system exhibits a gas-liquid-solid three-phase state

whereas it transforms into a gas-liquid two-phase state below 90 MPa. At 30 MPa

the precipitated liquid oil accounts for approximately 14 % of the total oil-gas volume. Therefore

under high-temperature conditions

pressure exerts a dominant control on the ability of natural gas to dissolve crude oil and on the phase behavior of oil-gas systems. In deep to ultra-deep reservoirs under ultra-high-pressure and high-temperature conditions

oil and gas accumulations with a GOR greater than 2 000 m

are basically classified as gas-condensate reservoirs characterized by a vaporous gas phase. Ultra-deep oil and gas reservoirs in the southern margin of Junggar Basin

such as the Well Hutan1 and Well Tianwan1 reservoirs

with GORs exceeding 2 000 m

are identified as vaporous gas-condensate reservoirs under in situ reservoir conditions. The natural gas in these reservoirs has dissolved most hydrocarbons originally present in crude oil

yielding condensate oils with relatively high densities at the surface.
