Oil Recovery Technology Project Design Of Baolige Oilfield Ba â…  Structure

Baolige oilfield in Bayindulan depression is a key productivity construction area of Erlian oildom in HuaBei oilfield. The main blocks of Baâ… structure includes Ba-10 block and Ba-48 block, in the basis of successful development and construction of Ba-19 block in Ba-II construction, according to the problem that low permeable sublayer,minor production,low reservoir energy,serious paraffin underground,poor natural conditions on the ground in the two fault blocks of the Ba-I construction, with the beginning of adaptability assessment of the current oil testing, in this paper, we commit some technical research by combining field investigation and indoor test,numerical simulation and the actual data fitting,theory and production experience in order to improve the liquid producing capacity of the oil well,optimization effective wax removal and inhibition technology,optimizing matching injection-production strategy. On this basis, we complete the oil production technology design of Ba-I construction by further analysis and appraisal, multi-program,multi-index contrast optimization. In the testing well-group,we have taken measures by commiting drop dosing, washing well and optimizing pumping parameters and other measures, interrupted pumping before the measures had been changed to continuous pumping for the two wells,the increase production of half a year is 115t which is a very good result.
