Development of Self-adaptive Plugging Material for Drilling Fluid

Petroleum Engineering Technology Institute of Southwest Petroleum Branch, Sinopec, Deyang, Sichuan 618000

摘要

摘要: 针对堵漏过程中易漏地层特征掌握不准确，现场堵漏材料自适应能力差，易造成堵漏效果不佳和堵漏后发生重复性漏失的情况。通过可变形材料的优选，同时利用现有刚性堵漏材料的特点，研制出一种具有较好抗压能力和弹性的自适应堵漏材料，抗温达170 ℃，69 MPa压力下可变形不破碎，压力去除后回弹率达80%，与钻井液配伍性好，形成的自适应堵漏配方能够对1～6 mm的变化缝宽形成有效封堵，漏失少，承压能力达6 MPa。

Abstract: In view of the fact that the characteristics of the easy-to-leak formation are not accurately grasped during the plugging process, the self-adaptive ability of the field plugging material is poor, and it is easy to cause the bad plugging effect and the repeated leakage after plugging. Through the optimization of the deformable material and the use of the characteristics of the rigid plugging material, a screw extruder is used to coat the deformable material on the surface of the rigid plugging material to achieve the effective combination of the two, an adaptive plugging material with good compression resistance and elasticity has been developed. The temperature resistance reaches 170 ℃, it can deform without breaking under 69 MPa pressure and the springback rate reaches 80% after the pressure is removed. The self-adaptive plugging formula can effectively plug the changing seam width of 1mm-6mm with less leakage and pressure bearing capacity of 6 MPa.
