The model consists of perforation, wellbore, cement casing, oil layer, micro-annulus and transverse fracture.
模型中包括射孔孔眼、套管、水泥环、油层、微环隙和横向裂缝。
2
Developed wellbore transient flow model and friction calculating method for the sand mixed fluids effected by propant.
建立了井筒不稳定流动模型，提出了支撑剂影响下的混砂液摩阻计算方法。

And rock mechanical parameters are essential to the wellbore stability evaluation, so developing the model of rock mechanical parameters evaluation while drilling becomes core of the work.
