JIN 45-32-18 Block Development Scheme Design And Economic Estimate

In this paper, JIN 45-32-18 block in Liao He oil field is researched. Reservoir in this block is thin, physical characteristics is bad and reservoir heterogeneous is acute, so there is no economic efficiency in straight-hole. As many advantages and adaptive capacity in horizontal well development, so we consider designing and deploying a horizontal well at JIN 45-32-18 block Da Ling He reservoir.The research work of the paper contains five parts as follows.1.Stratigraphic correlation and structural researchAt the base of utilizing drilling information and log data, then, constructing stratiaraphic correlation on thirty-six completed drilling well, we divide JIN 45-32-18 block S32 Da Ling He reservoir into layers and block.Applying three-dimensional seismic data and seismic explanation, on the basis of drilling data, we analyze and describe the structural feature and fracture feature.2.The research of depositional featureBased on core information and different sedimentation types, the research of sedimentation condition sedimentary facies of this reservoir are carried on deeply and in detail, in order to know the sedimentary environment and depositional feature.3.The research of reservoir characteristicBased on core analysis information and log data. We carry the analysis research on reservoir distribution, physical characteristics, reservoir heterogeneous characteristic and development distribution of intermediate from portrait to plane, form macro to microcosmic and from fix quantify to fix character, to ascertain mostly factor affecting reservoir physical characteristics and post radically inherence character of this reservoir.4.Oil and water distributing characterBased on structure research and reservoir characteristic research, using logging data, test oil and test producing information, reservoir portrait development, plane distributing status, reservoir type and liquid character are studied, to beat out distributing rule and control factor of reservoir, to spread oil reserve estimation in place, according to sandstone group unit and using numerical value simulation carry forecast of residual oil distribution on potential area. 5.Horizontal well deployment and economic estimateBased on structure research, reservoir character and distributing research, oil and water distributing character and economic estimate, a horizontal well is deployed in the work area.
