１．用途针对辽河油田稠油注汽井出砂严重的实际情况，辽河油田采油工艺研究院防砂中心研制了ＰＲ－ＳＣ／ＬＨ－Ｖ高强度固砂剂。其施工简单，成本低廉，防砂效果好，适用于井温高于１２０℃的油井防砂。２．基本原理ＰＲ－ＳＣ／ＬＨ－Ｖ高强度固砂剂粒度为２５０～４００目
1. Purpose In view of the serious actual situation of heavy oil injection well in Liaohe Oilfield, PR-SC / LH-V high-strength sand-fixing agent was developed by Sand Control Center of Oil Production Technology Research Institute of Liaohe Oilfield. The utility model has the advantages of simple construction, low cost and good sand control effect, and is suitable for oil well sand control with a well temperature higher than 120 DEG C. 2. PR-SC / LH-V high-strength sand-fixing agent particle size of 250 to 400 mesh
