摘要:
A dual gradient cementing system is modeled in a modeled subsea wellbore. The modeled dual gradient cementing system comprises a plurality of components including a mud lift pump (MLP) coupling a subsea rotating device (SRD) to a surface mud return line, wherein the MPL is located at a subsea depth and the SRD diverts annular fluids from an annulus away from a riser. The modeled dual gradient cementing system is simulated in operation, wherein a fluid loss value of 100% at the subsea depth of the MPL is assumed, and a fluid property of a simulated non-static fluid in the simulated dual gradient cementing system while in operation is estimated. Thereafter, an actual dual gradient cementing operation is performed in an actual subsea wellbore, wherein an actual non-static fluid corresponding to the simulated non-static fluid exhibits the fluid property.
摘要(中):
双梯度固井系统在模拟的海底井筒中建模。 建模的双梯度固井系统包括多个部件,包括将海底旋转装置(SRD)连接到表面泥浆返回管线的泥浆提升泵(MLP),其中MPL位于海底深度,并且SRD将环形流体从 一个远离冒口的环。 模拟双梯度固井系统在运行中模拟,其中假设在MPL的海底深度处的流体损失值为100%,并且在运行中模拟双梯度固井系统中的模拟非静态流体的流体性质 估计。 此后,实际的双梯度固井操作在实际的海底井眼中进行,其中对应于模拟非静态流体的实际非静态流体表现出流体性质。
