洛带构造蓬莱镇、遂宁组储层孔隙度和渗透率都较低,属于低孔低渗储集层,储层比较容易受到损害.本项目通过对该地区储层地质特征、现有射孔液存在的问题以及对储层的损害机理进行全面研究的基础上,通过对射孔液基液的确定和增粘降失水剂、粘土稳定剂、助排剂、缓蚀剂的优选,形成了一套适合于洛带地区蓬莱镇、遂宁组储层的优质射孔液体系.实验结果表明,新型射孔液对储层的损害率为30.36.2%,比原有射孔液对储层的平均损害率降低55%以上；缓蚀率在90%以上,缓蚀率较高,与原有盐水射孔液相比能够明显减轻对现场设备的腐蚀；新型射孔液与洛带气田现有钻井液、压裂液体系配伍性良好；其性能在常温、50℃、80℃条件下经过30天的陈化后总体性能保持稳定.为了避免射孔液使用后返排液对洛带气田环境造成安全环保问题,这里通过对射孔液返排液组分进行分析,探索研究射孔液的回收再利用,最终获得了一套射孔液的回收再利用方法,射孔液返排液回收利用后可节省60%以上的处理剂费用,并减小了对环境的污染程度,使洛带构造射孔液存在的技术和安全环保问题得到较好的解决.

Penglai Town, Suining Luodai Construction Group reservoir porosity and permeability is low, belongs to the reservoir of low porosity and low permeability, reservoir is vulnerable to damage. The project to conduct a comprehensive study on the mechanism of the existing characteristics, geological reservoirs of this area the existing problems and the perforating fluid to reservoir damage, by identifying and viscosity reducing agent, clay stabilizer, help the preferred agent, corrosion inhibitor for perforating fluid medium fluid, formed a set to suit in the Luodai area, Penglai town of Suining formation reservoir quality perforating fluid system. The experimental results show that, the reservoir damage model of perforation fluid rate was 30.7~36.2%, the average reservoir damage than the original perforating fluid rate decreased by more than 55%; the inhibition rate was above 90%, the corrosion rate is higher, can obviously reduce the corrosion of the equipment on the spot compared with original brine perforating fluid; new perforating fluid and gas fields in Luodai the existing drilling fluid, fracturing fluid system has good compatibility; its performance at room temperature, 50 ℃, 80 ℃ after 30 days after aging performance remained stable. In order to avoid perforation fluid cleanup liquid caused by security problems of environmental protection in Luodai gas field, here the perforating fluid flowback fluid component analysis, recovery of perforating fluid recycling, finally got the recycling utilization method of a perforating fluid, perforating fluid flowback fluid recycling can save processing agent over 60% of the cost, and reduce the pollution degree to the environment, make Luodai construction perforating fluid technology and safety and environmental protection problems be solved.
