Aiming at the problem that the water intrusion control factors of multi-stage fracturing horizontal wells in tight gas reservoirs in edge and bottom water are not clear, the linear supply boundary is used to characterize the water intrusion characteristics and derive the mathematical characterization formula, considering the stress sensitivity and diffusion mechanisms of tight gas, and the water intrusion flow model of multi-stage fracturing horizontal well in tight gas reservoirs in edge and bottom water is established, and the bottom pressure and its derivative curves are obtained by Laplace and perturbation transformation. Furthermore, the influence of water intrusion strength, matrix-fracture channeling capacity, storage capacity coefficient, fracture segment spacing, fracture conductivity and other factors on the degree of water intrusion and water exposure time were analyzed. By fitting the well test data of the established model, the water intrusion intensity parameters can be obtained, and the water intrusion control of gas wells can be guided according to this parameter. The data analysis of two typical wells in the western oilfield was carried out by applying the established model, and the analysis results were well matched with the actual production, which verified the reliability of the model, and according to the analysis results, the treatment measures of the two wells were proposed, and the two wells obtained good production results.

The chemical paraffin removal agent QLJ-1 was developed by analyzing the composition of crude oil, the wax content and the point of paraffin removal in the wellbore of an oilfield in northwest China. The orthogonal test was used to determine the formula as follows: mixed organic solvent (70% aromatics, alkane volume ratio of 2:2:1) + mixed surfactant (7% Tween-80, AEO-9, fatty acid salt mass ratio of 1:2:1) +23% pure water. The results of kinetics and emulsion stability study show that the saturated wax dissolution amount of QLJ-1 is 1.62 g, the wax dissolution rate is 0.0263 g/min, the wax dissolution equilibrium time is about 1h, and the emulsion stability time is 6 d. The wax dissolving effect of QLJ-1 is better than that of the current paraffin remover. The research results of this paper can provide technical support for improving the chemical paraffin removal process in an oilfield in Northwest China.
