增大单井出水量和保持高质量的水质及延长水井服务寿命是提高完井质量的主要指标。通过解淤实验和实地开挖的观测探明泥浆的渗透率和泥皮性能及流变学对出水通道的影响并得出改善这方面问题的主要技术措施。 选择含有害离子低的含水层进行开采和避免外界污染源。如对洗井液和下入井内的滤料进行卫生监测是提高水质的二个主要方面。 利用电化学原理防止滤水管的结垢和解垢处理,可以延长水井的寿命,系用氯化物及盐酸处理往往可以达到解垢疏通的目的。
Increasing single well water output and maintaining high quality water quality and extending well service life are the main indicators for improving well completion quality. Through the silting experiment and field excavation observation, we can see the influence of mud permeability and mud skin property and rheology on the water outlet channel and get the main technical measures to improve this aspect. Select low aquifer containing harmful ions for mining and avoid external pollution sources. Hygienic monitoring of washout fluids and filter media entering the well is the two most important aspects of improving water quality. The use of electrochemical principles to prevent the scaling of the filter pipe and the scale removal treatment can extend the life of wells, the Department of chloride and hydrochloric acid treatment can often achieve the purpose of cleaning dirt.
