Thesis For The Graduate Candidate Test The Development Program Optimization Of Horizontal Well In Liaohe Oilfield Jin 45 Block

Reservoir in Liaohe Oilfield Jin 45 Block is thin, physical characteristics is bad and stratum heterogeneous is acute, so there is no economic efficiency to exploit straight well. Using the drilling and well logging data to process stratum comparison with 36 drilling and completion wells in work area. on this basis, to divide Jin 45-32-18 blocks Sha3.2 section Da Linghe reservoir. Using the 3d seismic data interpretation, fine earthquake and combining with drilling data to research structure, analysis and describe the structural and fracture characteristics. According to the analysis data and logging data of the core, analyzing and researching the reservoir distribution, physical, heterogeneous characteristics and barriers development from lengthways to plane, from macroscopic to microcosmic and from the quantitative to qualitative. Defining the main influence factor of reservoir physics , then fundamentally revealing the inherent characteristics of the reservoir.This paper researches on oil and water distributing character which based on structure research and reservoir characteristic research. Using logging- data, test oil and test producing information to research reservoir portrait development, plane distributing status, reservoir type and liquid character. Beating out distributing rule and control factor of reservoir, spreading oil reserve estimation of petroleum geology according to sandstone group unit, and using numerical value simulation carry forecast of residual oil distribution on potential area. Researching on deployment of horizontal well and economic estimate which is based on structure researching, reservoir character and distributing researching, oil and water distributing character and economic estimate, through program optimization, then deploying a horizontal well in the work area.
