摘要
针对涠洲12-1S-2井的储层特点,国内首次构建了储层保护的甲酸盐水力喷射完井液体系,其基本配方为:海水+3%防水锁剂HFS+2%防乳破乳剂HFR+2%防垢剂HFG,甲酸钾加重。室内实验结果表明,该体系具有较好的防膨性、防水锁性、配伍性以及储层保护性等。径向射流甲酸盐喷射液于2011年7月在WZ12-1S-2井流一段进行了现场试应用。
In view of the reservoir characteristics at Weizhou 12-1S-1 Well,a hydraulic jet completion fluid of formate for reservoir protection was prepared for the first time. Its basic formulation is as follows: sea water + 3% anti water lock agent HFS + 2% emulsion proof and breaking agent HFR + 2% scale inhibitor and some potassium formate. The results of laboratory test have shown that this system is of good swelling inhibition,anti water lock,compatibility and reservoir protection properties. Field application test was carried out with radial jet completion fluid at No. 1 Flow Section of WZ12-1S-2 Well in July,2011.
