可压缩流体密度测试系统的设计与应用
|
摘要
低密度流体在石油工程中应用广泛,但实际作业中低密度流体在高温高压条件下具有可压缩性,导致密度的变化。目前流体密度测试多在常温常压中进行,不能反映流体在高温高压条件下的真实密度变化。因此开发了一种可压缩流体密度评价设备,其原理是利用公式ρ=m/V,固定试样的质量,通过测试体积的变化量,计算出密度的变化,操作安全、方便、测试精度高,测试范围温度0～150℃,压力0～60 MPa,可准确测试泡沫钻井液等低密度流体的密度变化情况。
The low density fluid is widely used in petroleum engineering. And the low density fluid can be compressed under high temperature and high pressure,which result in the change of the density. At present,the fluid density test is carried out at room temperature and atmospheric pressure,which can not reflect the true density of the fluid under the condition of high temperature and high pressure. Therefore a compressible fluid density evaluation equipment is developed,its principle adopts the formula of ρ = m/V to fix the specimen mass,and then to change the test volume to calculate the density change. The operation is safe and convenient with high test precision; the test parameter range covers the pressure 0-60 MPa and the temperature 0-150 ℃,the density changes of foam drilling low density liquid fluid can be tested accurately.
