Study And Experiment On The Technology Of Increasing Injection Technology Of Injection Wells In Yanchang Oil Field

At present, the extension of the oilfield has entered the stage of waterflood development scale, injection Wells in owe injector occupies than columns, although in the augmented injection measures implemented some augmented injection technology, however, due to the lack of targeted technology leads to its application effect is poorer. Therefore, according to current situation of augmented injection prolong oilfield, will owe injector division classification analysis, research owe note the reason, mechanism and corresponding augmented injection technology, improve the effect of augmented injection measures. Reservoir characteristics, the combined with extended oilfield water injection well percolation theory analysis and research, determine appropriate water injection parameters. Second, increasing water injection in low permeable oil fields, carry out to improve pore water injection capacity augmented injection technology research; In the aspect of increasing water injection technology, the multi-functional composite processing technology of treating agent and slug processing technology experiment analysis; In single augmented injection technology, the physical augmented injection technology to increase the radius direction, chemical augmented injection technology develops to respect of multi-functional treatment agent. By optimizing the augmented injection technology, improved technology, select the appropriate augmented injection technology, and field experiments, through field experiment, the effect tracking analysis, has been clear about the suitable for different horizon and extend oilfield owe note cause different well conditions and augmented injection technology and construction technology. To further improve augmented injection measures are effective, extend the augmented injection effect, realize the stable oil field production has important significance.
