锦州油田化学防砂技术综述

A Review on Chemical Sand Control Methods Used in Jingzhou Oil Fields

简介了锦州油田投入开发15年来不同时期主要用于热采稠油井的化学防砂技术原理和使用效果：以长效黏土稳定剂为主的稀油油藏固砂剂FSH-901（1992～1995，施工136井次，有效率78．7％）；无机钙／有机硅高温固砂剂BG-1（1992～1995，79井次，79．7％）；Ca（OH）2／CaCO3/机硅单体高温“三氧”固砂剂（1996～1997，98井次，82．7％）；高温泡沫树脂固防砂剂（1997，4井次，50．0％）：改性呋喃树脂防砂剂（1997-2005，99井次，94．9％）；氟硼酸综合防砂剂（1998-2002，130井次，81．5％）；有机硅固砂剂YL971（1998～2002，89井次，85．4％）；高强度有机硅固砂剂LH-1（2005，11井次，100．0％）。报道了防砂施工中出现的问题：出砂套变井逐年增多；多层舍采长井段井化学防砂难度大；出砂粒径逐年变细，表明油层骨架受到破坏。提出了化学防砂技术发展方向：研发常温固化的耐高温固砂剂；完善分层防砂工艺。参2。

The technologic principles and the field results of applying chemical sand control methods in Jingzhou oil fields, Liaohe, are presented briefly mainly for steam enhanced heavy oil production wells in 15 year＇s exploitation. These are： long term clay stabilizer based sand consolidation agent （SCA）, FSH-901, used in 1992-1995 136 well-times with effectiveness （Eff） 78.7% ; inorganic Ca/silicone SCA, BG-1, for high temperature use （HTU）, 1992-1995, 79 well-times, Eft 79.7% ; Ca（OH）2/CaCO3/monomeric silicones SCA for HTU, 1996-1997, 98 well-times, Eff 82.7% ; fouming resin SCA for HTU, 1997, 4 well-times, Eff 50.0% ; modified furan resin SCA, 1997-2005, 99 well-times, Eff 94.9% ; fluoroboric acid composite SCA, 1998-2002, 130 well-times, Eff 81.5% ; silicone SCA, 1998-2002, 89 well-times, Eft 85.4% ; high strength silicone SCA, LH-1, 2005, 11 well-times, Eff 100.0% ）. The trouble problems appeared in sand control operations are： continuous increase in the number of sand producing wells with casing deformed and/or injured; complicated sand control operations in commingled production wells with long sections of multiple pay layers; gradual reduction in the particle size of produced sands, indicating matrix being destroyed. Further researches in this field should be aimed at developing thermally resistant SCAs curable at low temperatures and improving technologies of zonal sand control.
