Study On Logging Interpretation Technology For Waterflooded Zone In Sapu Oil Layer Of Long Hupao Oil Field

Longhupao oil field is the early exploration important block by Daqing placanticline outskirts west, and entering high water cut stage, Sapu petroleum reservoir water flooding degree is high, must increase water flooding regime dynamics regulation. Because present well network oil layer use condition divergence larger, existence a great quantity of oil remaining, moreover subsurface profit distribute complex changeable, insufficiently is not deep enough also thorough to the reservoir flooding characteristic. in view of Daqing placanticline outer-ring west Sapu oil layer key sub-area development flooding level well logging interpretation engineering research.This paper in to studies the area reservoir characteristic multidisciplinary analysis in the foundation, will discuss using the graph theory clustering procedure to study the area reservoir division will be three kinds, through the development hydrocarbon reservoir condition under electric conduction mechanism experiment, will clarify in the different rock physics facies reservoir flooding process the electrical property answer change regular pattern. In the water flooded layer determine the nature recognition method research, through the introduction curve relative core, ellipticity, parameter and so on plump factor, the application porosity and resistivity logging curve deconvolution, has established four type of different rhythm oil layers waterflooding model, thus realizes to the reservoir contains oil/gas the disposition or contains water the natural information determine the nature judgement; In the flooding level oil well logging quantitative evaluation, take the degree of saturation appraisal as the core, the innovation mud character develops the blend to contain the calcium sandstone effective medium current specitic resistance model. This article through to the Daqing placanticline outer-ring west the Sapu oil layer development swept layer well logging interpretation technical research, has analyzed middle/low penetration oil field reservoir flooding rule, has established the flooding level recognition method and the standard. In view of reservoir the building store height mud to contain the calcium the characteristic to carry out the degree of saturation quantitative evaluation engineering research with emphasis.
