Yingcheng Group Volcanic Rock Reservoir Characteristic Research And Exploration Target Selection In Shengping Gas Field

Shengping gas field is located within the boundaries of the Heilongjiang Province Anda city north, the structure position is in southeast fault subsidence of Song liao northern deep structure unit, Yingcheng group volcanic rock reservoir is main reservoir.This article first reflects the characteristic according to the regional geology characteristic and the characteristics of the volcanic rock seismic reflection , the development volcanic rock three dimensional earthquake traces the explanation, through the position fine demarcation and the wave resistance characteristic contrast analysis, the union coherent body, the inclination angle examination and the entire three dimensional explanation technology, completes Yingcheng roup volcanic rock to go against the bottom surface tracing to explain, is clear about the research area volcanic rock and the sedimetary rock distributed characteristic, and determines the break the mop direction and the scale. Completes the entire area structure to become the chart, clarifies the conformation and the break mop characteristic.The full use core sample, the logging, the log information, have carried on Yingcheng group volcanic rock lithic facies the division based on the lithological character and the electrical characteristic, Analyzes in the single well facies foundation, the union seismic characteristic and the reservoir forecast result, has established the volcanic rock seismic deposition phase diagram. Technical methods and so on attention utilization seismic attribute analysis, describe the research area volcanic rock lithological character, the lithic facies distribution rule characteristic and the evolved characteristic accurately, and analyzes the volcanic rock lithological character, the lithic facies distribution gets a light from another light the precipice gas pool control action.Take the log information as the foundation, take theseismic structure explanation as the restraint, used the bore log restructuring technology, the inversion wave impedance, the density, gamma and so on the data bodies, forecast volcanic rock reservoir thickness and effective reservoir thickness.This article mainly obtained three aspects to know that,Structure framework understanding, volcanic rock lithic facies division, oil gas collecting band understanding.
