Regarding the slotted liner destruction caused under non-uniform loads, the effects of non-uniform loads on the collapse strength of slotted liner is studied, the mechanical model for slotted liner is set up, and the collapse strengths under different loads and the variations of the collapse strengths of the slotted liners with different thicknesses as non-uniformity changes are analyzed.
针对割缝管在非均匀载荷作用下引起套管损坏的问题,在研究非均匀载荷对套管抗挤强度影响的基础上,以有限单元法为基础,建立了割缝衬管的力学模型,分析了割缝衬管在不同载荷模式下的抗挤强度以及不同壁厚割缝衬管的抗挤强度随不均匀系数的变化关系。
According to the properties of Pinghu oilfield in East China Sea, the well completion method of A3 horizontal well is determined as initial well completion by slotted liner and later sand control by metal fibre screen pipe.
针对东海平湖油田的特点,确定了该油田A3水平井合理的完井方法是:割缝衬管先期完井和金属纤维防砂筛管后期防砂。
