Channeling Flow

Channeling flow frequently occurs during the high pressure water injection of low permeability reservoir. The injection process is complex and covers so many parameters of which the contribution to channeling flow is necessarily to be studied. In this paper, numerical simulation is combined with sensitivity analysis method to calculate the significance of the weight of parameters to the channeling flow. First the values of different parameters are produced by using Latin hypercube method; second, by using these parameters, finite element model have been established and simulated, and the quantity of channeling flow has been calculated; then Spearman rank relation is applied to measure the relation of parameters and channeling flow. The results states that, in 10 years continuous injection, the well spacing and injection pressure have significant impact on the channeling flow. This states that during the application of high pressure water injection, the pressure and well spacing should be controlled especially.

High Pressure Water Jet

Concrete crushing of the municipal engineering by traditional broken tools has flaws of inefficient, high dust pollution, high noise, high labor intensity. Hydraulic crushing equipment with ultra-high pressure water jet is designed, which includes the ultra-high pressure five-plunger pump unit and its control system. Engineering applications show the equipment owns characteristics of high efficient, cold state, security, and cannot produce stratified thermal aggregation, heat-affected zone in concrete and dust pollution. Then qualities of concrete hydraulic crusher in a complex environment are improved effectively. It provides an effective method to solve the problems of concrete hydraulic crushing.

To prevent threaten of impact disaster, high-pressure water is injected into coal face, which is most widely used in impact-type mine. In such cases, by analyzing the rock burst tendency of a particular type of deep mining pit and occurrence of the mining process, rock samples drilled from the coal mine were taken for the conventional mechanical properties test and rock burst tendency test respectively under dry and wet state. Cuttings volume indicator affected by injection has been optimized to improve the prediction sensitivity. "One shift anti-impact, two-shift production "patterns labor organization model, adjusted development system layout and cut drilling index optimizations, as well as the allocation of high-pressure water injection drilling means, greatly improving the water injection effect, which probably provide a reference for similar mines to safe and efficiently mining.
