一种双酚A型环氧树脂固砂性能的室内研究

针对油井在生产过程中的出砂问题，选取了一种双酚A型环氧树脂ER1用于化学固砂实验，研究了其化学式及主要反应机理。并在室内测试了ER1固砂体系的性能。结果表明．在60℃下选用40～80目干燥石英砂、固化剂GN加量为1．2％、ER1树脂加量为4．5％、偶联剂KH550加量为0．2％、固化时间为24h的条件下，散砂固结体的抗压强度为12．3MPa。空气渗透率为12．9md．煤油渗透率为4．1md。固结体样品能够抵抗地层水、泥质等的混入。有较好的耐酸碱等介质的能力，在大流量长时间水的冲刷下没有散砂被冲出。

Indoors Laboratory Study on Chemical Sand Consolidation of A Kind of BPA Epoxy Resin

In order to solve the problem of sand production which most oil wells face, ERI,a BPA epoxy res-in, has been chosen for chemical consolidation experiment, the chemical formula and main reaction mechanism of this resin has been studied. And the performance of ER1 consolidation systems are determined indoors. When the consolidation body for dry quartz sand of 40-80 mesh is obtained at 60 ℃ under the optimum consolidation conditions as follows： amount of consolidation agent GN of 1.2%, amount of resin ER1 of 4.50%, amount of coupling agent KH550 of 0.2%, consolidation time of 24 h, its compressive strength, permeability to gas, per- meability to kerosene is 12.3 MPa,12.9 md, 4.1 rod, respectively. And the consolidation body sample can toler-ate formation water and clay to some degree, and has a good resistance to acid and alkali. There is no friable sand washed out after large flow and long time water scouring.
