摘要

摘要: 因为水泥堵漏材料存在气密性差、注入性差等问题，亟需研制新型套管堵漏材料。介绍了长庆油田套管堵漏用液态树脂的选择与合成，对其性能进行了评价，并进行了现场应用。结果表明，长庆油田套管堵漏用液态树脂在60℃固化时间4.5 h，抗压118 MPa，与套管内外剪切强度达到26.1 MPa，与岩石黏接力达到10.5 MPa，耐油水性能强，可钻性优异。现场应用过程中，在镇A井套管堵漏复产及华B井套管堵漏重复压裂作业中表现良好。研究结果为液态树脂化学堵漏技术推广提供技术参考，为长庆油田套管损坏井治理提供一条可靠的技术路径。

Abstract: Cement slurry used as a lost circulation material in controlling loss of borehole fluids through casing string has long been faced with problems such as its poor gas tightness and injectivity. This paper introduces the development of a liquid resin which can be used to replace cement slurry in loss control and the evaluation of the performance of the resin. The liquid resin has been tried in field operations. It was found that after setting at 60℃ for 4.5 h, the resin had compressive strength of 118 MPa, the shear strength of the resin adhered on the casing string was 26.1 MPa, and the bonding strength of the resin with rock reached 10.5 MPa. The resin had good oil resistance and drillability. This resin has been used in the Well Zhen-A for controlling loss of borehole fluids and well produced again with good production rate. In another well Hua-B, after applying the resin, the well was re-fractured with good results. Field practice has provided a technical reference to the use of the liquid resin as a lost circulation material and a reliable technology for dealing with loss across the casing strings.
