Xingshugang Oilfield Apricot Three Districts, Injection Wells And Augmented Injection Measures To Optimize The Design Method

The method for increasing production is not effective enough because there are a lot of low water injection well and various water injection stratum in Daqing oil field, especially father more water injection method was executed one by one. And now increasing injection workload that is beneficial for cost is limited. It is very important that benefit can be gained with effective method of increasing production without repeating workload in Daqing oilfield.There are three problems about work of more water injection: first problem is how to confirm water injection quantity for some wells; second problem is the relation between the method of water injection and the quantity of water injection; third problem is how to confirm the type of water injecton.In this paper the author do great hard research in order to solve these problems. Fortunately these problems were solved mensurablly with math geology and reasonable geological informations by author. The reasonable water injection is controlled by stratum, the connectivity of sand bodies, stratum pressure and so on. So it is the key work that how to describe the seep coefficient, accumulate coefficient and connectivity of sand bodies mensurablly. The water injection quantity can be simulated with new parameters by analyzing these wells that are not polluted. Then the reasonable water injection upper limit well be confirmed by careful calculating. At last a lot of statistic work shoud be done about all kinds of methods of water injection in order to confirm the reasonable styel during these years. In a word some effective methods of water injection were put forward in this paper by author, and it is clear that these methods is important to water injection with most limited cost.
