    Abstract
  • In order to solve the prominent problems of high salinity and serious scaling of formation water in Lingshui 25-1 gas field, through the scaling trend calculation and experimental evaluation, the scaling risk of Lingshui 25-1 gas field is analyzed, the quantitative evaluation indexes of scaling degree such as adhesion coefficient are established, the experimental research on its influence law is carried out, and the scale inhibitor with good scale inhibition effect is optimized. The results show that there is a serious scaling risk in Lingshui 25-1 gas field under the conditions of formation temperature and pressure. The core test results show that the scale sample has a small adhesion coefficient and is easy to migrate with the fluid. The critical flow rate is 0.25 cm3/min. with the increase of displacement time, the core permeability gradually decreases and reaches equilibrium at about 1200 min. the maximum permeability change rate is 82.17%. With the increase of temperature, the scaling trend of formation water will be exacerbated, and the maximum permeability change rate is 81.86%; The preferred scale inhibitor ethylenediamine tetramethylene phosphonic acid (EDTMPA) has a good scale prevention effect on the static and dynamic scale prevention of formation water in different layers of Lingshui 25-1 gas field through strong metal chelation and lattice distortion.
