Abstract

​

In conditions of abnormally low reservoir pressures (ALRP), when the bottom-hole pressure of the fluids pumped into the well is significantly higher than the reservoir pressure in the intervals of highly permeable rocks, various complications arise in the technological processes of drilling and well repair. Due to the absorption of washing fluids, violations of the stability of the well bore and other complications, the quality and cost of the work performed is reduced.

At the same time, it is not always possible to reduce the repression on the bottom-hole zone of the reservoir to the required values.  In the article, based on the analysis of a large experience of drilling and repair of gas wells in the conditions of anpd, the conditions of the state of the well-formation system at different values of the anomaly coefficient of low reservoir pressure ( ) are shown. It is established that the value of relative repression on the formation increases by hyperbolic dependence when decreases from 0.85 to 0.061.

Key words:

​

process fluids, gas-liquid systems, gas wells, abnormally low reservoir pressures, opening of a productive reservoir, well repair
