Study On Optimization And Deployment Of Development Objectives Of Horizontal Wells In MLQ Area

The proven reserves submitted in the S2 section of the MLQ area of the YT Basin are currently only produced in part of the well area,and both the proved unproduced and unproved areas have great potential.The fine structural interpretation method is used to carry out fine well-seismic calibration on the basis of the pre-processed 3D seismic data,to clarify the corresponding relationship between reservoirs and earthquakes,and to establish a reasonable geological model.Carry out targeted characterization of the fan body,clarify the plane distribution law and the vertical superposition relationship,and use the reservoir prediction method on this basis to identify the effective fan body and the reservoir within the fan body,and determine the plane distribution range and reservoir characteristics of the oil layer.Use seismic attribute analysis methods to detect the oil and gas properties of the target area,carry out research on the distribution law and effectiveness of the barriers,calculate the reserves of each reservoir unit,and synthesize the structure,sand body thickness,sedimentary facies,oil layer thickness,and reserves.The size is rated for each reservoir unit.Using the numerical simulation method,the optimal design of the horizontal wells in the MLQ block is carried out from the six aspects of development mode,horizontal well direction,well spacing,row spacing,initial production of a single well,and well pattern selection.Hirai's optimization design work.Through the systematic evaluation and research on the tertiary reserves in the MLQ area,the large-scale development and production of the benefit area are optimized;the research on the optimization and deployment of the horizontal well development target is carried out,and the difficult-to-recover reserves production method is solved,so as to realize the continuous construction of production capacity in the MLQ area.Lay a reliable foundation for selecting the best development plan in this area and provide a basis for steadily expanding the development scale.
