The Development Of Technology Of Double Two Countermeasures Research On The Northwest Margin Of Moliqing Oilfield

Yitong Basin is complex fault basin, is characterized by complex structures, reservoir sedimentary stability of underwater fan, oil properties of plane, vertical difference. Moliqing fault depression through the exploration practice in recent years, according to the problems in the exploration and development of complex faulted basin is facing, effectively carry out management innovation, strengthen the geophysical, geological logging, multi-disciplinary joint research, combined with the importance of experimental study and field practice in a relatively short period of time, the formation of the complex fault depression basin of fine technology research reservoir and effective practice, carry out fine reservoir description, characteristics of petroleum geology in Moliqing area clear. Accelerate the pace of Yitong Basin in Jilin oilfield exploration and development can alleviate the ultra low permeability reservoir development and poor efficiency of the actual situation, Jilin oilfield is important to assure the production.Y59 block is located in the northwestern margin of Moliqing fault depression, complex geological conditions, the two sand group of Shuangyang Formation oil bearing is controlled by tectonic factors, different tectonic position of oil reservoir with a full degree, reservoir conditions, the oil and gas production, oil content was mainly affected by the lithology, reservoir physical factors, according to the description of reservoir space control and fault block 59, double two period of Iranian oil water layer recognition, the establishment of oil water layer identification standard of well area, combined with the reservoir controlling factors, complete fault containing oil reserves, overall implementation of 1667×104t, clear the development potential and direction of adjustment. The geological reserves of order 943 ×104t, step outside the geological reserves of 687.6 ×104t, five sand group of geological reserves of 36 ×104t.Moliqing fault depression has 45 pair of strata,located in the northwestern margin of the basin and the southeast, steady well test and production test data of these two blocks are, at the same timeTherefore, Shuangyang Moliqing Oilfield Group, two sets of oil-bearing series in order to determine the efficient development.
