| Abstract: | This article analyses the stress change of cement sheath after cementing by using elastic theory, makes sure the failure mechanism of cement sheath plugging and obtains the way of improving cementing quality . On these basis, LSS plastic cement system is developed. Through practice, the results show that its property surpass regular cement system, and can improve cementing quality and the period of validity of cement sheath plugging. |
